But prices are still on average 9% lower than a year ago.
Comprehensive car insurance premiums rose by 1% (£8) in the third quarter of 2018, according to research by Confused in association with Willis Towers Watson.
The findings suggested a stabilisation after previously falling at their fastest rate compared to the last time prices dropped in 2014.
According to the Car Insurance Price Index the small increase ends the series of significant price cuts across four consecutive quarters, which saw premiums fall to £752 from a price peak of £847 in the second quarter of 2017.
The index revealed that UK motorists are now paying an average of £760, which is 9% less than they were paying this time last year.
