Tamika and Joel, who are both 17, said they were concerned about the impact new peer passenger laws, which restrict red P-platers to just one passenger after 11pm, may have on young drivers.

"I live just out of town and use my car to travel to school, work, TAFE and whatever else I want to do," Tamika said.

"When a group of my friends are going to the movies or something late at night it's going to make it hard, it's going to mean loads more cars on the road for starters."

As well as the peer passenger restrictions, the new laws include a ban on all mobile phones, including hands-free, and a zero-tolerance approach to speeding.

Red P-platers who are caught going over the speed limit stand to lose their license for at least three months.

"It's only really the curfew law that I don't agree with," Joel said.

"It's blown the NRMA's designated driver program right out of the water for P-platers.

"There's going to be more cars on the road and it could lead to more P-platers driving without their P's late at night."

New restrictions have also been brought in for L-plate drivers.

Previously L-platers had to complete 50 hours of driving with a licensed passenger.

With the introduction of the new legislation that has now increased to 120 hours of driving, with a minimum of 20 hours night driving.

Learners will also have to stay on L-plates for at least 12 months, rather than the previous six months, regardless of their age.
