POLICE in Hampshire have launched their annual Christmas drink- and drug-driving campaign.

Operation Holly started on December 1 and will run for a month.

A spokesperson for Hampshire Constabulary said: “We can now test on the roadside for certain drugs and only a trace amount of an illegal drug is a person’s system could lose their licence like drink driving. We don’t have to prove you are impaired.”

Members of the public are asked to report drink or drug drivers by calling 999 if they believe the person is an immediate risk. Otherwise, people can call 101 with details of the last seen location of the vehicle, make and colour and registration if known.

The force's summer drink- and drug-drive campaign saw a total of 545 people arrested. Some 3,327 motorists were tested.
