A study has shown that drivers aged 17 and 18 are six times as likely to have an accident as those older than 50.
Insurers Admiral said the young drivers were twice as likely to have a road accident as motorists in their 30s and three times more likely than those in their 40s
Around 10% of drivers aged 17 and 18 had been involved in a crash - compared with 4.5% of drivers in their 40s.
It was also revealed that accidents involving young drivers in the same age group cost twice as much as those with other motorists.
The study of two million motorists tabled an average cost of £3,500 for an accident involving someone aged 17 or 18. This was compared with an overall average of £1,741.
The higher average cost led the insurer to claim that young drivers were involved in more serious crashes at high speed.
Admiral managing director Sue Longthorn said: "From our point of view, driving experience makes a huge difference and is the main reason older motorists have lower premiums."
