Drunk driving law by country

The laws of driving under the influence vary between countries. One difference is the acceptable limit of blood alcohol content before a person is charged with a crime.

Asia

Central Asia

• Kyrgyzstan: 0.05%^[1]
• Mongolia: 0.05%^[1]
• Turkmenistan: 0^[1]

East Asia

• China: 0.02%. Over 0.02% but under 0.08%: 元 1000–2000 fine, 6 months licence suspension; Over 0.08%: up to 3 years imprisonment,^[2] 5 years licence suspension. If the driver causes serious injuries or death, the license will be suspended for life.^[3]
• Hong Kong: 0.05% or BAC 0.22 mg/L or urine 0.067%. Driving under the influence of alcohol beyond legal limit is punishable with a monetary fine and up to three years imprisonment, with 10 driving-offense points and mandatory Driving Improvement Course.^[4]
• Japan: BrAC 0.15 mg/L (equivalent to 0.03%). Additionally, regardless of alcohol readings, police may also determine the driver to be "driving drunk", which is punished more severely than exceeding the designated alcohol limits.^[5]
• Republic of Korea: 0.03%^[6]
• Taiwan: 0.05% (BrAC 0.15 mg/L). Over 0.05% but under 0.11%: TWD 15,000 to 90,000 fine, and license suspension for 1 year. 0.11% and above: license suspension for 1 year, and charge of offences against public safety with possible prison sentence up to 2 years as the maximum penalty. If the driver is convicted of causing accidents, the penalty shall be increased by half. If the driver causes serious injuries or death, the license will be suspended for life or even face the death penalty.

South Asia

• Afghanistan: 0^[1]
• India: 0.03%. This is according to section 185 of Motor Vehicles Act 1988. On a first offence, the punishment is imprisonment of 6 months and/or fine of 2000 Indian Rupees (INR). If the second offence is committed within 3 years, the punishment is 2 years and/or fine of 3000 Indian Rupees (INR). The clause of 30 mg/dL was added by an amendment in 1994. It came into effect beginning 14 November 1994.
• Nepal: 0%. Breathalyzer testing is regularly used in major cities like Kathmandu, Pokhara, Biratnagar and Highways. For more verification, driver will be taken to nearest hospitals for blood and urine test (if demanded by the driver). Licence will be seized instantly. Driver will get the licence back after attending anti-alcoholic classes run by Nepal Traffic Police and fine will be charged NRS 1000.
• Pakistan: Falls under Drink and Drugs, S. No 14. No Set limit. 8 Penalty Points.^[7]
• Sri Lanka: 0.06%. Breathalyzer testing is not used routinely. If suspected by police the driver is produced before the closest government medical officer who examines and determines whether the driver is under influence. If the driver refuses examination by the medical officer he is considered to have been under influence by default.

The Criminal Law Amendment Act, 1968–69 made it a per se offence to drive with a BAC in excess of 80 mg/100 ml of blood. Refusal of a police officer's demand to provide a breath sample was made an offence at the same time and both began as summary conviction offences, with a mandatory minimum $50 fine.^[20]

Mexico

• Mexico: 0.04–0.10%.^[21]

Foreigners with recent (in the past 10 years) drunk-driving criminal convictions are generally refused entry at the border. Mexico's Immigration Act section 36 considers any foreign drinking and driving outstanding charge or conviction as an Indictable offense (similar to a felony).

United States

• United States: 0.08% BAC by volume

Some states now have two statutory offenses.^[22] The first is the traditional offense, variously called driving under the influence of alcohol (DUI), driving while intoxicated/impaired (DWI),^[23] operating under the influence (OUI), or operating while intoxicated/impaired (OWI). The second and more recent is the so-called illegal per se offense of driving with a blood alcohol concentration (BAC) by volume (mass of alcohol/volume of blood) of 0.08% (previously 0.10%) or higher. In most states, the timing of the chemical test is important because the law mandates a result within a given time period after the driving stopped, usually two hours. The first offense requires proof of intoxication, although evidence of BAC is admissible as rebuttably presumptive evidence of that intoxication; the second requires only proof of BAC at the time of being in physical control of a motor vehicle. An accused may be convicted of both offenses, but may only be punished for one.^[24] The differences between state penalties still varies. Wisconsin, for instance, is the only state that continues to treat first offense drunk driving arrests as forfeiture.^[25]

Some states also include a lesser charge of driving with a BAC of 0.05%; other states limit this offense to drivers under the age of 21. All states and DC also now have zero tolerance laws: the license of anyone under 21 driving with any detectable alcohol in their bloodstream (BAC limits of 0.01% or 0.02% apply in some states, such as Florida.) will be suspended. In 2009, Puerto Rico joined these states, setting a limit of 0.02 for drivers under 21, despite maintaining a legal drinking age of 18.^[26]

The blood alcohol limit for commercial drivers is 0.04%.^[27] Pilots of aircraft may not fly within eight hours of consuming alcohol, while under the impairing influence of alcohol or any other drug, or while showing a blood alcohol concentration equal to or greater than 0.04 grams per decilitre of blood.^[28]

Caribbean

• Bahamas: 0.08%^[1]
• Cuba: 0 for young or inexperienced drivers and professional or commercial drivers, 0.05% for all other drivers.^[1]
• Dominican Republic: 0.03%^[1]
• Jamaica: The law states that the legal alcohol limit is 35 μg/100 ml alcohol in breath or a blood alcohol level of 80 mg/100 ml alcohol in blood.^[29]
• Trinidad and Tobago: 35 μg/100 mL BrAC, 80 mg/ml BAC^[30][31]

Central America

• Belize: 0.08%^[1]
• Costa Rica: 0.05%^[1]

South America

• Argentina: 0% for public transport and commercial vehicles, 0.02% for motorcycles, and 0.05% for all others.^[33]
• Bolivia: 0.05% for professional drivers only.^[34]
• Brazil: Any BAC up to 0.06% results in a fine and 12-month suspension of the driver's license. Anything above 0.06% is considered a criminal offense.^[35][36]
• Chile: From 15 March 2012, 0.03–0.08% the driver is considered to be driving under the influence and carries a three-month suspension and a fine of US$82–410 (as of 19 March 2012); over 0.08% the driver is considered to be drunk and carries a prison term of 61 to 301 days, a fine of US$164–820 (as of 19 March 2012) and a two-year suspension for the first offense, a five-year suspension for a second offense, and a life suspension for a third offense.^[37]
• Colombia: Colombia is known to have the toughest penalties against those driving under the influence in all of Latin America and practice a zero tolerance policy on DUIs. If a driver is found to be driving with 20–39 mg/100 ml ethanol in blood (equivalent to 0.02–0.039% BAC), the driver is to have their license suspended for a year, pay a fine of US$914 (as of 22 December 2013), and serve 20 hours of community service. In the most extreme cases, if a driver is found to be driving with grade three alcohol (150 mg/100 ml ethanol in blood), the driver is to have their licence confiscated for 10 years, pay a fine of US$7,314 (as of 22 December 2013), and serve 50 hours of community service. If the driver gets in an accident and causes injuries and or deaths, the driver is to face between 2.5 and 18 years of prison sentence.^[38]
• Ecuador: 0.01% for commercial or professional drivers, 0.03% for all other drivers.^[1]
• Guyana: 0.08%^[1]
• Paraguay: 0
• Peru: Drivers below a 0.05% BAC will be given a warning. At a 0.05% and over, the driver will be given a fine and a license suspension of no less than 6 months and no more than 2 years. If the driver is involved in an accident without causing death or severe injury to another individual, he or she may possibly face jail time. If the driver's causes an accident with a BAC over 0.101%, involving death or severe injury to another party, he or she will receive a mandatory prison sentence of 3 to 5 years. The driver's license will also be permanently revoked.
• Suriname: 0.05%^[1]
• Uruguay: 0.03% for amateur drivers (since March 2009) and all other drivers and 0 for professional drivers.^[1] The driver will have to pay a fine of US$464 (as of 29 April 2015) and will have their licence suspended. Depending on the concentration of alcohol in blood and the times the driver was found guilty the suspension goes from a minimum of 6 months to a maximum of 2 years.^[39] If the driver causes an accident involving death, he or she will be charged with negligent homicide and will face a minimum of 6 months in prison.
• Venezuela: 0.08%^[1]

For aggravated, also a prison sentence (60 days to 2 years) is possible,^[46] usually as a suspended sentence. Routine breath testing without a probable cause is permitted and often practiced. Penalties vary by level of intoxication.
• France: 0.05% or 0.02% for new drivers (under 3 years of driving license) and bus drivers (€135 fine and 6 demerit points on the driver's license, which can be suspended for 3 years maximum),^[12] 0.08% (aggravated, criminal offense, license suspension for 3 years, €4500 fine, and up to 2 years imprisonment)
• Germany: Zero for beginners (less than 2 years' experience or under the age of 21), professional drivers, bus drivers, truck drivers, and drivers transporting passengers commercially; 0.03% in conjunction with any other traffic offense or accident; 0.05% otherwise. For cyclists, the limit is set at 0.16%, where not in conjunction with any other traffic offense or accident. From 0.16%, cyclists face the same penalties as driving a car at that limit.^[47]
  Penalties start at a €500 fine and 1-month license suspension. From 0.11%, the penalty is a €500 fine and the withdrawal of the driver's licence for at least 6 months, but usually about 1 year (penalty is set by the court); from 0.16%, reissue of the licence requires a successful Medical Psychological Assessment (MPU).^[48] From 0.11% within 10 years of an offence from 0.05%, there is a minimum €7003100000000000000♠1000 fine and a 1-year licence withdrawal; the driver has to successfully pass an MPU and is required to prove to the court that they have been sober for the last 12 months, before they can get their licence back. For repeat offenses, the fine is multiplied by the ordinal of the offence (doubled, tripled, etc.), regardless of the amount by which the driver was over the limit. These minimum penalties are usually exceeded by the German courts. From 0.11%, the courts usually also require the DUI offender to do unpaid community service.
• Gibraltar: 0.05%^[49]
• Greece: 0.05% (BrAC 0.25 mg/L),^[12] reduced to 0.02% (BrAC 0.10 mg/L) for unlicensed or new drivers who have held a license for less than 2 years, motor cycle and professional drivers. Above 0.11% (BrAC 0.60 mg/L) it's considered a flagrant misdemeanor punishable with up to 2 years of imprisonment and a hefty fine in the court plus the revoking of the drivers licence for 6 months. Routine breath testing without a probable cause is permitted and practiced by the traffic police, especially on weekends and major holidays.

Being convicted of drunk driving usually carries a 2-year ban as well as a €1500 fine.^[51]
• Italy: From 0.05% to 0.08% (€500-2000 fine, 3–6 months license suspension), from 0.08% to 0.15% (aggravated, €800-3200 fine, 6–12 months license suspension, up to 6 months imprisonment), over 0.15% (aggravated, €1500-6000 fine, 1–2 years license suspension, 6 to 12 months imprisonment, vehicle seizure and confiscation), zero for drivers with less than 3 years experience and professional drivers (bus, trucks, etc.). License is always revoked in case of: professional drivers, second offence committed within two years or in case of an accident. If the driver refuses examination he is considered to have been under influence by default applying the over 0.15% rules.^[52] Limit is zero for newly qualified drivers (those who have their license for less than three years).

Further rules in the United Kingdom (UK)

In the UK, driving or attempting to drive whilst above the legal limit or unfit through drink carries a maximum penalty of six months' imprisonment, a fine of up to £5,000 and a minimum 12 months' disqualification. For a second offence committed within ten years of conviction, the minimum ban is three years. Being in charge of a vehicle whilst over the legal limit or unfit through drink could result in three months' imprisonment plus a fine of up to £2,500 and a driving ban. Causing death by careless driving when under the influence of alcohol or other drugs carries a maximum penalty of 14 years in prison, a minimum two-year driving ban and a requirement to pass an extended driving test before the offender is able to drive legally again.

It is an offence to refuse to provide a specimen of breath, blood or urine for analysis. The penalties for refusing are the same as those for actual drunk driving.

The offence of driving whilst under the influence of alcohol is one to which there is no defence, as such (although defences such as duress or automatism, which are not specific to the offence of driving with excess alcohol, may apply in certain rare circumstances). However, it may be possible to argue that special reasons exist which are such that you should not be disqualified from driving despite having committed the offence. Special reasons are notoriously difficult to establish and the burden of proof is always upon the accused to establish them. Such reasons may include:

• shortness of distance driven
• unintentional commission of the offence (i.e., laced drinks)
• emergencies

Magistrates' sentencing guidelines

In England and Wales when DWI offenders appear before a Magistrates Court, the magistrates have guidelines they refer to before they decide on a suitable sentence to give the offender. These guidelines are issued by the Sentencing Guidelines Council^[72] and cover offences for which sentence is frequently imposed in a magistrates' court when dealing with adult offenders.

Offences can either be tried summarily which means they can only be heard in the magistrates court or they can be either way offences which means magistrates may find their sentencing powers are insufficient and indict the case to crown court. The majority of drunk driving offences are summary only offences which can only be tried in a magistrates court. Only the most serious offences such as a collision and/or death/injury involved are indicted to crown court. The maximum sentence magistrates can usually impose is a £5000 fine and/or a six-month prison sentence.

As with England and Wales, road traffic law in Scotland is in the main framed within the Road Traffic Act 1988 as amended. Prosecution and disposal of drink-drive offences is broadly similar to England and Wales with less serious cases prosecuted on complaint through the sheriff summary courts. Cases involving aggravations, life-changing or fatal injuries are prosecuted on indictment via the sheriff solemn or high court. As with most UK-wide legislation, the penalties and sentencing guidelines for drunk driving in Scotland mirror those in effect in England and Wales.

Oceania

Australia

Road laws are state or territory based, but all states and territories have set similar rules.

Australian law allow police officers to stop any driver and perform a random breath test without reason. Roadblocks can be set up (for example, leading out of town centres on Friday and Saturday nights and after football matches or other major events), where every single driver will be breath-tested.

This differs from UK and US laws, where police generally need a reason to suspect that the driver is intoxicated, before requesting a breath and/or sobriety test. It is an offence to refuse to provide a sample of breath when requested, with severe penalties including prison.^[73]

Australian Capital Territory

• 0 for drivers or riders holding a learner, provisional, restricted or probationary license and for drivers operating heavy vehicles over 15t GVM or driving a public vehicle for hire or reward (for example taxi and bus drivers).^[74]
• 0.05% for all other drivers.

New South Wales

• Zero for Learner and Provisional licences.^[75]
• 0.02% for drivers of vehicles of "gross vehicle mass" greater than 13.9 tonnes, vehicles carrying dangerous goods or public vehicles such as a taxi or bus.
• 0.05% for all other drivers
• 0 limit for methamphetamine, Cannabis and MDMA.

Northern Territory

• 0 for provisional (probationary) licence holders and all motorcyclists.
• 0.05% for all other drivers.

Queensland

• A 0 limit applies to the drivers of trucks, buses, articulated vehicles, vehicles carrying dangerous goods, pilot vehicles, taxis, all learner drivers and provisional drivers and RE class licensed motorcyclists in their first 12 months.^[76]
• 0.05% for other drivers.^[77]
• 0 limit for methamphetamine, Cannabis and MDMA.^[77]

South Australia

• 0 limit for learner, provisional, probationary, heavy (greater than 15 tonne) vehicle, taxis, licensed chauffeured vehicles, dangerous goods, and bus licenses.
• 0.05% for all other drivers.
• 0 limit for methamphetamine, Cannabis and MDMA.

Tasmania

• 0 limit for learner, provisional, truck, bus, and taxi licences.
• 0.05% for all other drivers.
• 0 limit for methamphetamine, Cannabis and MDMA.

Victoria

• 0 limit applies for unlicensed drivers, holders of learner permits and probationary licences, "professional" drivers, and certain relicensed drunk-drivers.
• 0.05% for all other drivers.
• 0 limit for methamphetamine, Cannabis and MDMA.

There are also other restrictions for drivers in Victoria:

• Limits apply within 3 hours of driving - that is, police can require a person to submit to an alcohol or drugs test within 3 hours of driving and it is an offense to fail that test, unless the drug or alcohol use occurred after driving (see Road Safety Act 1986, ss. 49, 53 and 55E).
• Licenses canceled for certain serious drunk-driving offenses may only be reissued after obtaining a court order. This is the case for repeat offenders, and first offenders above 0.15% . In such cases, the relicensed driver is subject to a 0 limit for 3 years following relicensing, or for as long as the person is required to use an alcohol interlock.
• Alcohol interlocks must be imposed whenever a repeat drunk-driver is relicensed.
• A court also has discretion to impose an alcohol interlock when relicensing a first offender in certain serious cases, generally when the offense involves a BAC of 0.15% or higher.
• The law requires interlocks to be used for certain minimum periods, but the requirement to use an interlock does not automatically end at the completion of the minimum period. Once that period has expired, an individual may apply to a court to have the interlock condition removed from their driver's licence. The State Police must be given notice of the application and may make submissions to the court on whether the interlock condition should be removed. The court will also take into account data recorded by the interlock itself (e.g., whether any attempts were made to start the vehicle by a person who had been drinking).
• Driving without an interlock when one is required carries severe penalties, including imprisonment.
• If a doctor sees any patient who is aged 15 years or over as a result of a motor vehicle accident, the patient must allow the doctor to take a blood sample for testing for alcohol and drug content in a way that preserves the chain of evidence. If this process is skipped the doctor may not be able to discover the alcohol blood level. The results can be used as evidence in subsequent court proceedings.
• The law allows a police officer to require any driver (or any person who has driven a vehicle within the last three hours) to perform a random saliva test for methamphetamine, Cannabis or MDMA, all of which are subject to a zero limit (see Road Safety Act 1986: ss. 49, 55E & 55D)

Western Australia

• 0 for learner and probationary licence holders and persons convicted of driving under the influence and/or failing to comply with a request for breath, blood or urine (for three years after the offense).
• 0.05% for all other drivers.

Readings over 0.08% but under 0.15% BAC, and 0.15% BAC and above (legally defined as Drunk Driving) comprise separate offenses, the latter attracting heavier penalties. Persistent offenders may be barred from driving for terms up to and including life, and may also be imprisoned.

The law allows a police officer to require any driver to perform a random saliva test for methamphetamine, Cannabis or MDMA, all of which are subject to a zero limit.

New Zealand

New Zealand operates a program called Compulsory Breath Testing, which allows police to stop motorists at any time. CBT is usually carried out at roadside checkpoints but mobile patrol cars can also randomly stop motorists to administer a test. The police also carry out roadside drug tests upon motorists they suspect have used drugs.^[78]

The system in New Zealand is age-based.^[79] the limits are:

• 0 limit for persons under 20 years.
• 0.05% BAC or 250μg/L breath for persons 20 years and over.

The penalties for exceeding the limits are:

• Persons under 20 years, up to 0.03% BAC, 150 μg/L breath: instant NZ$200 fine and 50 demerit points.
• Persons under 20 years, 0.03–0.08% BAC, 150–400 μg/L breath: up to 3 months imprisonment and/or up to NZ$2250 fine; loss of licence for three months or more.
• Persons 20 years and over, 0.05–0.08% BAC, 250–400 μg/L breath: instant NZ$200 fine and 50 demerit points. 12 hour prohibition from driving immediately after^[80]
• All persons over 0.08% BAC, 400 μg/L breath (first and second offenses): up to 3 months imprisonment and/or up to NZ$4500 fine; loss of licence for six months or more.
• All persons over 0.08% BAC, 400 μg/L breath (third and subsequent offenses): 2 years imprisonment; NZ$6000 fine; loss of licence for one year or more.

Note that penalties apply to the lowest reading taken across both breath and blood tests. For example, if a driver 20 years or over has a breath test result of 426 μg/L but a subsequent blood test returns 0.077% BAC, then the driver is not charged with any drink driving offence despite the breath reading being over the breath alcohol limit. The penalty for injuring or killing someone when under the influences is the same as dangerous driving (up to 5 years imprisonment and/or up to NZ$20,000; loss of licence for one year or more).
