NSW Police has launched an operation to target drink, drug, dangerous and distracted driving in an attempt to prevent road trauma over the Christmas-New Year period.

Operation Christmas-New Year 2021 will commence on Christmas Eve and conclude at 11.59pm on Monday, January 3.

Double demerit points will apply for the duration of the operation for speeding, mobile phone, seatbelt, and motorcycle helmet offences.

Deputy Premier, Minister for Regional NSW and Minister for Police Paul Toole said police would have a strong presence in the regions, with more people than usual leaving Sydney to reunite with family and friends.

"For many, it will be the first time they've hit the road since COVID restrictions eased, so please plan ahead, take your time and be patient," Mr Toole said.

"No one wants to get a fine or worse still, lose their licence at Christmas, but we make no apologies for taking a tough stance so everyone can be reunited with their loved ones safely."

Traffic and Highway Patrol Commander, Acting Assistant Commissioner Paul Glinn, said police are expecting the roads to be busy with the easing of COVID-19 restrictions and more people travelling to see loved ones.

"Keeping the public safe is our top priority - and we're asking for you to help us protect yourselves, loved ones and the community on NSW roads," Assistant Commissioner Glinn said.

"If you see or know anyone who is drink, drug, dangerous or distracted driving, please report it to Crime Stoppers and we will investigate.

"Our message to motorists breaking the law is clear: someone is watching you now and you will get caught," Assistant Commissioner Glinn said.
