The Automobile Association wants the $100 million revenue generated from traffic fines to be spent on road safety.
It says more than 16,000 people were injured or killed in road crashes last year, costing more than $4.5 billion.
The AA says New Zealand's record could be improved if the fines paid by motorists for traffic infringements, was spent on road safety engineering and education.
Both National and Labour say they have reservations about the idea, as overseas experience shows motorists view the policy as a revenue generating exercise.
