Police have launched a Christmas crackdown on drink and drug-drivers. 

Around 300 Sussex Police officers are now fully qualified to test motorists for drugs at the roadside, in addition to the hundreds more officers already trained to test drink-drivers.

The investment in the crackdown coincides with the launch of Surrey and Sussex Police's Christmas campaign which runs from Thursday December 1 to Sunday January 1. 

The Christmas campaign will see Surrey and Sussex Roads Policing Units carry out dedicated patrols 24/7 across the two counties to put the brakes on motorists who take to the road while under the influence of intoxicating substances.

Superintendent Chris Moon, Head of Surrey and Sussex Roads Policing Unit, said: "There is no safe limit for driving under the influence of drugs or alcohol. Our advice is simple – go cold turkey or do not drive. If you're tempted just think of the consequences; you could lose your job, your home or your life. And remember even if you opt to take the sensible way home at night you may still be over the limit the following morning.

"Driving with drink or drugs in your system impairs your judgement and ability to drive safely. Not only can you cause injury or death to others, being caught drink or drug-driving can also have other consequences such as a criminal record, a heavy fine, losing your job and your licence, an increase in your insurance premiums and trouble travelling to certain countries.”

Drivers caught drink or drug-driving can expect to face a minimum 12-month disqualification, up to six months imprisonment and a fine of up to £5000. If a death is caused through dangerous driving while over the limit, a sentence of up to 14 years behind bars can result.

Officers no longer have to prove that a motorist is fit to drive; only that the driver has an illegal level of drugs in their system when on the road.

Supt Moon added: "If you have or are planning to drink alcohol, plan your journey home without driving. Don't offer an alcoholic drink or drugs to someone you know is planning to drive. And don't accept a lift from a driver who you know has drunk alcohol or taken drugs."
