Cumbria Police are launching their annual Christmas drink/drug-driving campaign today (Monday).
Officers have been trained how to administer drugs wipe tests, which test saliva to see if a driver has taken drugs such as heroin or cocaine.
They're also trained in other tests to see if a driver is under the influence of substances which a traditional alcohol or drug wipe test wouldn't pick up.
Chief Inspector Andy Wilkinson said: “We are committed to getting as many officers as we can trained in the use of drug wipes and administering Field Impairment Tests. Every time one of our officers stops a drug or drink-driver and gets them of the road has the potential to save that person’s life and the lives of other road users and pedestrians.
“We have reached a point, in 2017, that everyone knows that drink-driving is wrong. Yet there are still those who decide to do it.
“It may be that they think it is worth taking the chance because they might get away with it. Well, the training we are putting our officers through mean the chances you will be caught are increasing all the time.
“And those who are caught are the fortunate ones. All they lose is their licence and, maybe, their livelihood. Those we don’t get to in time could lose their life or face many years in prison for taking someone else’s.”
Cumbria’s Police and Crime Commissioner Peter McCall said: “As hard as it is to believe in this day and age, there are still too many irresponsible people out there who will risk their lives, and those of innocent victims, by getting behind the wheel under the influence of drugs or alcohol; I was out in the early hours with our roads police this morning and saw evidence of this for myself.
"For that reason I welcome this campaign, and be assured, officers are now better equipped to catch those that defy the law. The simple message is just don’t do it, but if you do, you will be caught.”
