Northern Ireland car insurance customers have been reminded of the costly effect that speeding convictions can have on the price of their premiums, though the region pales in comparison to other parts of the UK when it comes to housing boy racers.

In its analysis of almost three million motor insurance quotes over a year from people with driving convictions, comparison site Money Supermarket found that Scotland, Swindon and Sheffield are home to the most speeding convictions across the nation. Their research revealed that over half of speeding convictions in East Dunbartonshire, Scotland belong to male motorists aged between 17 and 21.

"It is telling there are no female drivers anywhere near the top of the table in our analysis of speeding convictions, and unfortunately this is reflected in the price of premiums for men when compared to women," said the site's Steve Sweeney, who warned that motorists in Northern Ireland and the wider UK convicted of speeding could see their car insurance costs almost double.

Furthermore, he noted, "serial speeders" will eventually find that fewer car insurance providers are willing to offer them cover at all, and if they do it will be at an increasingly high cost.
