"National will also introduce a tougher restricted licence test early next year to encourage young people and novice drivers to spend more time practising their skills under supervision before they are able to drive solo."
Motorcycle licence testing would also be strengthened and a power-to-weight restriction introduced for novice motorcyclists, he said.
Mr Joyce said young drivers were disproportionately represented in fatal and serious crash statistics.
He said improving the safety of young drivers is a priority for National as young drivers are disproportionately represented in fatal and serious crash statistics.
"Last year 15 to 19-year-olds made up 7.4 per cent of New Zealand's population and 6.1 per cent of all licenced drivers, but they were involved in around 17 per cent of all serious injury crashes."
He said young drivers caused 60 deaths and 385 serious injuries in crashes in the last year alone.
The party also announced it would would invest $12.2 billion on improving the high-use highways - the Roads of National Significance programme - over the next 10 years.
The road safety policy includes spending $620 million a year from the National Land Transport Fund to improve road safety.
National Party Leader John Key said the party would spend $295 million on safety improvements over the next three years, and $300 million on road policing.
The party would make "common-sense law changes" to target groups and behaviours that have the most impact on our road toll, as well as making engineering improvements to make well-travelled routes safer, he said.
