A lapse in coverage for a week up to 30 days will hike your car insurance rate by an average of 9%, or about $130, a year. A 60-day lapse gets you a 13% increase, about $190 more a year. But you'll see in the chart below that in some states a 60-day lapse can cost as much as 20% to 48% more. If you still want to suspend coverage, keep in mind that even if you follow the law and submit your plates, you still may be charged more for insurance after youâve had a lapse of, say, more than 30 days. Insurers say their statistical models show that drivers who havenât carried steady, uninterrupted insurance coverage tend to file more claims, and so cost the insurance company more.
