YORKSHIRE drivers are the worst in the country, says a survey.
One in six Tykes has a motoring conviction, says online car insurance search engine Confused.com
Law-abiding Northern Ireland is top of the UK league, with just 5% of people having points on their licence.
One conviction puts an average of £74.60 on insurance premiums, with two adding £182.92 and three leading to an extra £301.84.
Confused.com spokeswoman Debra Williams said: "These figures can look daunting, but it's important to realise not all insurers penalise in the same way.
"If you have points on your licence shopping around can bring back major savings."
A spokeswoman for Huddersfield-based road safety pressure group Brake said dangerous driving could end up hurting you a lot more than your pocket.
She said: "While the high level of driving convictions in Yorkshire is of real concern, risk-taking on the road brings tragedy to families across our country.
"We need drivers to put safety first every time they get behind the wheel.
"But we also need the Government to get tough with drivers who laugh in the face of the law, putting lives at risk when they drive.
"Brake is urging the Government to make road policing a priority.
"We want the Government to ensure there are enough traffic police to catch dangerous drivers and get them off our roads before they kill and maim themselves or others."
