Estimated premium increase: 10 percent
As with repeat drunken driving violations, multiple speeding tickets will bring you ever-increasing insurance costs. Get enough of them, and you can bet your insurance will be canceled, say the experts.
Insurers initially may waive one speeding ticket if it's within 10 mph over the limit, Hunter says. Some states won't even record the ticket if you take a safe-driving class.
But if your insurer doesn't want to cut you any slack, or you were far over the limit, speeding can raise your car insurance premium by about10 percent, according to Hunter's research.
Chronic lead-foots also pay higher traffic fines with each ticket -- up to $2,000 or more, depending on the state. And some states impose jail time.
NHTSA estimates that speeding is involved in more than 30 percent of all fatal crashes -- and costs the economy more than $40 billion a year.
