From tomorrow, double demerit points will be applied for a number of states around the country. But in many other jurisdictions it will be business as usual, even as our roads get busier. Here's a state by state breakdown of when or if double demerits start in your area.

Double demerit points apply for motorists in the ACT from Friday, December 22 until Monday, January 1, 2024.

The same applies for NSW if you’re heading down the coast or whereever.
