A. You'll generally get a discount if your auto and homeowners or renters insurance are with the same company, and you may get an additional discount on all of your policies for adding umbrella coverage. Most insurers give you a break if you are insuring more than one car, or for remaining accident-free for a given number of years.
You may get a break for taking a defensive-driver course (although some insurers offer these discounts only to senior drivers or teenagers). If your child is a full-time student and maintains at least a B average in high school or college, a discount of about 15 percent is typical. Most insurers give you a discount if your child moves more than 100 miles away from home for college and doesn't take a car, but the insurer will still provide coverage while your child is home for vacations.
Several insurers offer discounts for members of the military, and some have special breaks for some professionals (such as teachers) or members of certain groups (such as alumni associations). Most also give you a discount for paying your premium in a lump sum rather than monthly, and for using paperless billing and automatic payments.
