Drivers face double-demerit points if they break the road rules across the King’s Birthday long weekend.

Double demerits apply in NSW and the ACT from Friday and will continue across the long weekend until Monday, April 8.

Drivers face double demerits for speeding, illegal mobile phone use, not wearing a seatbelt or wearing a seatbelt incorrectly or riding without a helmet.

Additional penalties could apply for offences committed in NSW school zones on Friday.

“You’ll face double the points, not double the fine. You can stop it or cop it,” Transport for NSW warns on its website.

In Queensland, double-demerit points apply year round if a driver has committed a previous offence within 12 months.

Double demerits are applied after a second speeding, mobile phone, seatbelt or motorcycle helmet offence.

Victoria, South Australia, Tasmania and the Northern Territory do not have a double-demerit point scheme.
