Wherever you go on your next road trip or family vacation, you may want to avoid some common roadblocks to a pleasant trip. Here are a few pointers on preventing breakdowns and driver fatigue:

• Do you need that? Make a list before packing the car.

• Check Your Tire and Your Tire Pressure.

Tires can lose pressure quickly, and proper inflation helps prevent blowouts. It also helps to improve fuel economy.

• Check Your Car's Fluids and Wiper Blades.

Have your oil changed. Also, check the coolant/antifreeze mixture in your vehicle's radiator. Inspect the wiper blades. Also, check the windshield washer fluid reservoir. Don't forget your car's battery. If it is more than three years old, have it tested at a certified automotive repair facility.

• Prepare for Roadside Emergencies.

Create a kit that contains a flashlight, flares and first-aid basics. Bring along jumper cables, a mat or blanket and some basic tools to help change a tire. Also, add some water and nonperishable food in case of a breakdown.
