Operation Holly is a month-long campaign to tackle drink and drug-driving.
Hampshire Constabulary and Thames Valley Police's Joint Operations Unit have started the combined campaign to raise awareness of the dangers of driving under the influence of alcohol or drugs.
Their slogan, "It's Not Worth the Risk" targets reckless drivers about the distress caused by road collisions.
The campaign starts today (1st December) until 1st January and officers will be carrying out breath tests, drug tests and field impairment tests at every opportunity.
Police are also encouraging the public to report drink and drug drivers.
On average, 20 percent of all fatal collisions involve drink or drug impairment.
In Hampshire and Thames Valley region around 400 drink drivers are caught every month.
Sgt Scott Kerr, Road Safety Sergeant for Hampshire and Thames Valley Police said:
“Every year officers deal with cases of drink or drug driving that directly result in families facing Christmas without loved ones.
“Even the smallest amount of alcohol or drugs in your system can affect your ability to drive safely.
“Friends, colleagues and family members can positively influence those around them.
"So we are calling on them to stop potential drink or drug drivers from getting behind the wheel and risking tragedy this Christmas.
“We’ll be running targeted operations across the region to enforce the law on drink and drug driving.
"If you drive under the influence, you can face a fine of up to £5,000, disqualification from driving, and a lengthy prison sentence.
“If you know someone who drink or drug drives you can help by reporting them on 101, or call 999 if they are driving or immediately about to drive under the influence.
“I am urging people to plan ahead during the festive season to think about how you’re going to get home and don’t forget about the impact alcohol & drugs can still have the morning after.”
Their message reads:
DON’T DRINK OR DRUG DRIVE - IT’S NOT WORTH THE RISK.
