Beds Police are cracking down on drink-driving and driving under the influence of drugs during the festive period.
Police officers will be carrying out breath tests and where necessary field impairment tests to any motorists who have been involved in road collisions.
They will also be on the lookout for any suspicious driving and will stop and check anyone who is suspected of committing a driving offence.
Chief Inspector Richard Hann, from the joint Beds, Herts and Cambs Roads Policing Unit said: “We are supporting this campaign to raise awareness in drivers that any alcohol in your system can impair your judgement, cause difficulty assessing road conditions and ultimately cause a serious collision.
“Individuals’ reaction times will be slower and they will be less likely to observe what is going on around them.”
