The average car insurance premium rose by 8% in the past year to £462, says the Association of British Insurers.
The ABI said the £34 rise had pushed average premiums to their highest level since its records started in 2012.
The main reasons were higher repair bills, increases in insurance premium tax and the continuing issue of whiplash claims.
However, the figures are much lower than those recently published by the price comparison site Confused.com.
Earlier this month it said the average premium had risen by £110 in the past year, to the much higher level of £781 for a comprehensive policy.
