Check the horn, windshield wipers, and all the interior and exterior lights in your vehicle before setting out on a road trip. Put a few extra fuses and bulbs in your toolbox in case something goes out on the road. You don't want to waste valuable beach time looking for an auto parts store. Get someone to stand outside of the car while you try out the brake lights. A ticket is not a vacation souvenir you'll cherish. Change the wiper blades, too -- you know it's been awhile. Make sure the air conditioner is working at peak performance, and take the vehicle to the shop if it seems to be a little sluggish. That road trip will seem much longer if you're sweltering on the highway.
