Drink and drug driving

Provisional drink drive casualty stats for 2013 published in February 2015 by the DfT show a potential increase in drink drive deaths – to an estimated 260 in 2013 from a confirmed 230 in 2012. The figures show that around 15% of all deaths in reported road traffic collisions involved at least one driver over the limit.

By drinking and driving, you risk your life, those of your passengers and others on the road.

Morning After Campaign

Transport for Buckinghamshire are supporting The ‘Morning After campaign’.

The morning after campaign, which has been running for several years, is designed to help normally responsible people avoid the risk of a drink drive conviction - or worse still, cause a collision or casualties while ‘over the limit’ - by highlighting how long it takes for alcohol to pass through the body.

To download the ‘Morning After’ Calculator app and for more information about the campaign visit:

On average it takes around one hour per unit of alcohol, though this can vary depending on a number of factors. Nearly one in five people who are convicted of drink driving are caught the morning after and do not realise that they can still lose their licence if they are over the legal alcohol level.

The Morning After Calculator App has been designed by Stennik and developed by SoftApps.

Drug Driving

It is illegal to drive if your driving is impaired by drugs or if you have certain drugs above a specified level in your blood.

If the police stop you and think you’re on drugs they will either test you at the roadside using a drug screening device or a "Field Impairment" test to assess your ability to drive.

You don't have to be on illegal drugs to be impaired to drive – prescription or over-the-counter medicines can also impair your ability to drive. If you’re taking medicines, talk to your doctor, pharmacist or healthcare professional before driving.

Changes to the drug driving law

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 certain drugs above a specified level in your blood - just as it is with drink driving. Sixteen legal and illegal drugs are covered by the law, including cannabis, cocaine, ecstasy and ketamine. The limits for all illegal drugs are extremely low – taking even a very small amount of an illegal drug could put you over the limit.

The new offence will work alongside the existing offence of driving whilst impaired through drink or drugs.
