New drivers aged under 21 should be banned from carrying passengers of a similar age in their cars for six months after passing their test, the AA has claimed.

The motoring organisation said it also wants those motorists to be handed six penalty points for not wearing a seatbelt during the same period, which would mean they lose their licence.

To aid police enforcement a “G” plate should be displayed on young drivers’ cars, to highlight that they are a “graduate” driver, the AA proposed.

These measures would be a form of graduated driving licensing (GDL), which is used in several countries, including the US, Canada, Australia and Sweden.

The AA estimated that introducing GDL in the UK would save at least 58 lives and prevent 934 people being seriously injured in road crashes each year.

Department for Transport (DfT) figures show 290 people were killed and 4,669 were seriously injured in crashes on Britain’s roads last year involving at least one driver aged 17-24.

AA chief executive Jakob Pfaudler said: “Not only is this a tragic waste of life, but it contributes to the burden of high insurance premiums for young drivers.

“These premiums should fall when there is evidence of a reduction of young drivers and passengers killed and seriously injured.

“Graduated driver licensing has been proven in other countries to significantly reduce road deaths and serious injuries.

“We are calling on the Transport Secretary to make simple, pragmatic changes to the licensing process so young people are better protected in their first few months of independent driving.”

The most popular element of the AA’s proposal, according to an online survey of 10,566 of its members, was passenger restrictions, with 33% of respondents saying they would support them.

Last week, senior coroner for north-west Wales Kate Robertson raised concerns about young, newly qualified drivers carrying passengers after an inquest into the deaths of four teenagers who drowned when their car rolled into a ditch in November last year.

A DfT spokesperson said: “Every death on our roads is a tragedy and our thoughts remain with the families of everyone who has lost a loved one in this way.

“Whilst we are not considering graduated driving licences, we absolutely recognise that young people are disproportionately victims of tragic incidents on our roads, and we are considering other measures to tackle this problem and protect young drivers.

“That’s why we are committed to delivering a new road safety strategy – the first in over a decade – and will set out next steps on this in due course.”
