The recently released earthquake forecast and map by the U.S. Geological Survey serves as a reminder to prepare homes for the eventual earthquake, but Southern Californians, who drive a total average of about 300 million miles daily, should remember to be ready for an earthquake while driving, too, according to the Automobile Club of Southern California.

"Most of us are familiar with the techniques of responding to a quake while indoors, but we may not be aware of how to react if an earthquake occurs while driving," said Steve Mazor, manager of the Auto Club's Automotive Research Center. "Given the amount of time spent traveling, motorists should be prepared for major emergencies."

Experiencing an earthquake while in a moving vehicle has been compared to driving on four flat tires.

The Auto Club offers these tips to better prepare car owners if an earthquake occurs while they are driving:

Gradually decrease speed

Pull to the side of the road when safe to do so

Do not stop on or under overpasses or bridges

Do not drive until it's safe to do so

Avoid parking near trees, downed power lines and buildings

Stop the car and keep your seat belt fastened

Remain in your car until the shaking stops

Keep in mind that aftershocks follow the initial earthquake

Turn on your car radio and listen for advisories (most radio stations are prepared to broadcast emergency information)

If driving on the freeway, and if it's safe to do so, exit at the first opportunity

Cooperate with public safety officers because they are trying to ensure your safety and that of others

Be prepared by stocking the following items in your vehicle:

Fully equipped first aid kit

First aid manual (comprehensive)

Bottled water

Non-perishable foods

Blanket or sleeping bag

Flashlight with extra batteries and bulb

Fire extinguisher (CO2)

Pocket radio with extra batteries

Tissues and pre-moistened towels

Tools (screwdriver, pliers, wire, pocket knife, can opener and duct tape)

Extra clothes and sturdy shoes

Short rubber hose for siphoning

Sealable plastic bags

Local maps

Matches

Toiletries

Gloves

Prescription medicine

Note: Motorists should keep their vehicle's gas tank at least half-full at all times, and should not carry spare gas in the trunk.
