Learners would be able to get behind the wheel six months earlier than is currently allowed, but they would also have to take lessons for up to a year.

After passing the test strict new restrictions, including the compulsory display of P-plates for six to 12 months, would apply in a bid to cut road accidents.

It is thought the shake-up would reduce the number of deaths caused by inexperienced drivers by up to 1,000 a year and the total number of crash casualties by 7,000.

Engine size

In all 18 proposals are being considered in the government's review of the way licences are awarded.

The restrictions for new drivers could include:

• Tougher drink-drive rules
• Lower speed limits
• Limits on night-time driving
• Maximum engine size on cars
• Compulsory professional tuition for learners and accompanying drivers
• Compulsory skid and motorway training
• Minimum waiting period for re-tests
• Probationary licence code for two years
• A second practical driving test

'Impractical'

Announcing the plans Road Safety Minister David Jamieson said: "Too many new drivers are being injured on our roads because they are not getting enough experience before they take the driving test.

"We want to prepare them for their driving career, not just to pass the test."
