How Soon After Buying A Car Does It Need To Be Insured? 
Your state probably requires that you have auto insurance before you drive out the dealers driveway . Your current policy may well provide coverage for a specified period of time -LRB- usually 30 days . -RRB- Many consider that free coverage . That is not the case as the policy on the newly acquired car will revert back to the date of purchase . The best idea is to provide the dealer with evidence of current coverage and then call your insurance agent with all the details including the VIN , the date of purchase , the price of the car and any coverage changes that are necessary . That way you are covered and that is really the issue .
