Fill up with gasoline before you leave town. It's smart to keep your tank full during hurricane season.
Check your vehicle's fluid levels and ensure there is adequate coolant in the radiator.
Don't forget your tires. Check for proper air pressure because hot road surfaces are rough on tires. Be sure that your spare tire has air and that you have the proper equipment to charge your tire. Ensure you have a jack and lug wrench in your vehicle and know where they are in the vehicle. Your owner's manual should have instructions for changing tires and flats.
Make sure to carry water and non-perishable food for you and your passengers in case you become stranded.
If you are stranded, stay with your vehicles and use emergency flashers. Tie a wash cloth on antenna or door handle and raise the hood.
Carry a cell phone. You may need assistance. DPS help line is 800-525-555 or *DPS (on certain wireless carriers).
Have a working flashlight and extra batteries in your vehicle.
