Road safety charity Brake is backing the National Police Chiefs Council summer drink and drug driving campaign, urging drivers to enjoy themselves responsibly. 

The charity is asking drivers to pledge not to drink any alcohol or take any drugs before getting behind the wheel.

The enforcement campaign will see police across England and Wales stepping up roadside alcohol and drug checks, and warning the public about the risks. For the first time, the summer crackdown will see the use of roadside drug screeners, following the introduction of a zero-tolerance drug drive law in March 2015.

As part of last summer's campaign, 63,688 drivers were breathalysed, of who 4,108 failed the test - a slightly increased failure rate on the year before, possibly due to increasingly targeted enforcement.

As the weather improves over the summer, some people may be tempted to have a drink as they travel to and from BBQs, festivals and other events. Brake is urging everyone to leave the car at home or ensure they have a completely sober designated driver for summer festivities, and to look out for friends and family by making sure they plan ahead to get home without putting lives at risk.

Julie Townsend, deputy chief executive at Brake, said: "We believe drink driving is becoming more and more socially unacceptable in the UK, further aided by the lowering of the drink drive limit in Scotland at the end of last year. The new drug drive law introduced in March was also an important step in catching risky impaired drivers. However, there is a long way to go to stamp out this menace completely, as a selfish minority continue to get behind the wheel after drinking alcohol or taking drugs. We urge all drivers to ensure they are not part of that minority; instead we can all be part of the solution by making sure we can get home safely from summer festivities, and looking out for friends and family and ensuring they stay sober behind the wheel.

"Even one small drink or small amounts of drugs make you a danger on the road, so the only safe policy is not to drink or take drugs at all if you're driving - not a drop, not a drag. Feeling fine does not mean you're safe to drive. That's why Brake continues to campaign for a zero-tolerance drink drive limit, and greater priority to be given to roads policing, to make clear drink and drug driving won't be tolerated."
