Here is a link to an excellent article from Kiplinger’s about the effect on a ticket on your car insurance rates.
Here are some numbers that grabbed my attention:
A DUI boosts premiums by 93%, on average, and reckless driving hikes rates by an average of 82%…
Even a citation for a less serious moving violation can cause a big increase. For example, premium hikes average 18% for driving in a carpool lane and 19% for failure to yield to pedestrians. The impact of a speeding ticket depends on the speed. On average, rates increase 21% for driving 1 to 15 miles per hour over the limit, 28% for 16 to 30 mph over the limit, and 30% for more than 30 mph over the limit. (In some states, excessive speed is considered reckless driving.)
The specifics can vary a lot by insurer and state.
