A study of car insurance prices has found that young drivers can pay more than a quarter of their salary for a car policy. The study, by Confused.com, reveals that the average premium for a 17-20-year-old is £2,499, while the average salary for an 18-21 year old is £13,972. That makes the average policy around 18% of the average salary – although the average premium for a young man is a massive £3,635, well over a quarter of the average salary.
