What is the penalty if you have a gap from time you purchase a car from a dealer until you obtain auto insurance?

Temporary Dealer Gap insurance is considered the same as having no insurance at all. Most companies don't recognize dealer gap insurance because they are only excess secondary coverage policies, No Liability coverage is generally included in them. Generally if you have a lapse of 30 days or more, or if you have had continuous coverage for less than 6 months, then you will pay 5 to 10 percent more on premium. Beware of GAP Insurance, I've seen more than a few people who got burned on these after they discovered the gap only covered a portion of the vehicle and offered no liability coverage for the driver. * As a Broker, I can tell you it really depends on: the length of time, WHY the gap, your past record, and the individual underwriting policy for each insurer. Be SURE to tell any prospective broker/company of this gap or you could be without in the end!
