Legal Limit for Alcohol

The current legal limit for alcohol is:

  • 35 micrograms of alcohol in 100 millilitres of breath
  • 80 milligrams of alcohol in 100 millilitres of blood
  • 107 milligrams of alcohol in 100 millilitres of urine

Remember - you can't guess your limit. The only safe drink to have before you drive is one with no alcohol in it.

On 2 March 2015, the drug driving law changed to make it easier for the police to catch and convict drug drivers.
It is now an offence to drive with any of 17 controlled drugs above a specified level in your blood. This includes illegal and medical drugs. The limits set for each drug is different, and for illegal drugs the limits set are extremely low, but have been set at a level to rule out any accidental exposure (i.e from passive smoking).
Officers can test for cannabis and cocaine at the roadside, and screen for other drugs, including ecstasy, LSD, ketamine and heroin at the police station. Even drivers that pass the roadside check can be arrested if the police suspect that your driving is impaired by drugs.
The consequences

The penalties for drug driving are the same as for drink driving. If you are convicted you could face:

  • A minimum 12-month driving ban
  • A criminal record
  • An unlimited fine
  • Up to 6 months in prison
  • An endorsement on your driving license for 11 years

The consequences of a drug drive conviction are far reaching and can include:

  • Job loss
  • Loss of independence
  • The shame of having a criminal record
  • Increase in car insurance costs
  • Trouble getting in to countries like the USA

Anyone who suspects someone is regularly drinking and driving should contact Crimestoppers with the details on 0800 555 111. Remember the call is free, you do not have to give your name and you may receive a reward.
