IT is the season of Christmas work parties, having a drink while visiting your family and having a good festive time with your friends - but what do you do if you think someone might be about to get behind the wheel after a session in the pub? 

Avon and Somerset Police is taking part in Operation Tonic which takes place from December 1 2017 until January 1 2018. This sees officers carrying out vehicle stop-checks, targeted patrols and awareness-raising in pubs and bars.

If you are caught drink or drug driving, you will be disqualified. You will also receive a minimum 12-month driving ban, a criminal record, and a fine of up to £5,000.

The legally defined limits are:

35 micrograms of alcohol in a 100 millilitres of breath

80 milligrams of alcohol in a 100 millilitres of blood

107 milligrams of alcohol in a 100 millilitres of urine

So, how do you report someone? Avon and Somerset Police says if you believe someone is currently drink-driving, call 999. 

If it's just a suspicion, you can report a suspected drink/drugs driver:

By texting the word 'drunk' with brief details of the car, location and driver to 07400 279101

Online — fill in the Give us Information about suspected crime form on A&SP website

In person — at your local police station

On the phone — call 101

By email -

It's helpful to have the person's name and address, car model and registration, and where the person drinks or what drugs you believe the person has taken when reporting the incident.
