The campaign is co-ordinated by TISPOL (the European Traffic Police Network), and involves officers conducting alcohol and drug checks at any time of the day and night.

TISPOL president Aidan Reid said: “Driving after consuming even a small amount of alcohol is dangerous. Drivers will experience slower reactions, poor judgement of speed, reduced co-ordination and concentration, even with low levels of alcohol in their system.

“No one else can force you to drive while under the influence of alcohol or drugs. It’s a choice you make, and we urge you to ensure you make the safe choice. So if you have had a drink, do not drive. If you need to drive, then do not drink.

“Also, don’t get into a car if you suspect the driver has been drinking alcohol or taking drugs. Instead, make a responsible decision and call the police immediately.”

The campaign is also warning drivers that it’s important to be aware of the continuing effects of alcohol the day after an evening of drinking and will also target drug driving.

Mr Reid added: “If you have used recreational drugs, then do not drive. If you are taking medicine, whether prescribed or purchased over the counter, then read the notes of advice that go with it. If these tell you not to drive after taking the medicine, then do not drive. The advice is there for a reason, to keep you and others safe. 

“If you are in any doubt about medicines and driving, then our advice is to consult a healthcare professional before you get behind the wheel.”
