Likewise, a child moving out of the parent's house may reduce the premium.

Most auto insurance companies recognize this drop in annual driving as a reduction in risk and willadjust premiums accordingly.

It's true that when some people retire, they hit the road to see the world. In such cases, they mightput more miles on their vehicle than they did when driving to work every day. However, the averageperson drives less. The core question should always be: "Will you be driving less as a result of thechange?" Baisden says.

According to Barry, risks increase in urban areas compared with more rural ones. Rates ofvandalism, theft and even accidents increase with greater traffic density and all figure into premiumcosts.

Changes in the structure of your household should spark an auto policy review and perhaps increaseor lower premiums.

According to Barry, 12,000 miles per year is the typical mileage of a commuter going to and fromwork, as well as general traveling and errand running.

Elaine Baisden is a vice president at Travelers Insurance. She says a simple rule of thumb for olderdrivers is that any change impacting vehicle use should trigger a car insurance review.

Although the following five events could apply to a driver of any age, older drivers aremore likely to experience them because of the normal issues of aging.

Just as with the price of real estate, auto insurance premiums are heavily influenced by location,location, location. Barry says where the car will "live" is a key factor in premium cost.

"For a 10-year-old, or older, car, it doesn't make sense to have collision coverage," he says. He saysthat wrecking a 10-year-old car might cause $4,000 in damage on a car that's worth only $5,000 or$6,000. At some point, collision coverage won't pay for itself. On the other hand, Barry encouragesolder drivers to maintain their comprehensive coverage -- insurance that pays for damage to yourcar caused by something other than a wreck -- regardless of the vehicle's age.

Adult children might move into and out of your home with some regularity. If such an adult child isgoing to drive a parent's car, he or she should be added to the parent's car insurance, increasing thepremium. "An adult child living in the house and on your policy will affect the premium," Barry says.

Retiring and moving to a fixed income could well affect an older driver's credit worthiness andability to pay his bills. Older drivers should be keenly aware of changes in their credit score. Thisisn't something car insurance companies typically check, but other changes, such as an accident ortraffic ticket might cause an insurer to investigate more comprehensively. A significant drop incredit score that turns up in such a check could negatively affect an auto policy premium.

According to Barry of the Insurance Information Institute, dropping collision coverage -- insurancethat pays for damage to your car from a wreck -- on an older car may be the fiscally smart action totake.

Divorce or death of a spouse was another auto insurance review trigger listed by Barry.
