Since summer is the season for long road trips, both personal and business related, the National Highway Traffic Safety Administration recently issued a press release reminding motorists of the importance of preventive vehicle maintenance.

Regular maintenance such as tune-ups, oil changes, battery checks and tire rotations go a long way toward preventing breakdowns. You may want to pass along these tips to your drivers.

NHTSA reminds motorists that it’s important to perform the following basic safety checks before a trip:

Tires — Air Pressure, Tread Wear, Spare

The best way to avoid a flat tire, or the even more frightening experience of a blowout, is to check the vehicle’s tire pressure at least once a month — and don’t forget to check the spare. A tire doesn’t have to be punctured to lose air. All tires naturally lose some air over time. In fact, under-inflation is the leading cause of tire failure.

If your vehicle is a truck, van or SUV, monitoring your tire pressure is critical to your safety. These vehicles have higher centers of gravity and are more prone to rollover than cars when their tires fail. If your vehicle, tires or both are older, you need to exercise special care with regard to tire inflation and tire condition (including worn out treads or obvious damage), particularly in warm weather.

When towing a trailer, it’s important to know that some of the weight of the loaded trailer is transferred to the towing vehicle. If you are towing, make sure you inflate your tires to the recommended pressure. You can check the tire information placard or the owner’s manual for the vehicle’s maximum recommended load and for the correct tire pressure.

Check the air pressure in all your tires, including the spare. To get an accurate reading, check pressure when tires are cold, meaning they haven’t been driven on for at least three hours. It’s a good idea to keep a tire pressure gauge on hand in your vehicle for this purpose. You can find the correct pressure for your tires listed on a label inside the driver’s doorframe or in the vehicle owner’s manual — the correct pressure is not the number listed on the tire itself.

Also, take five minutes to inspect your tires for signs of excessive or irregular wear. If the tread is worn down to 1/16 of an inch, it’s time to replace the tires. Use the Lincoln’s head penny test, or look for the built-in wear bar indicators to determine when it’s time to replace the tires. Place a penny in the tread with Lincoln's head upside down and facing you. If you can see the top of Lincoln's head, you are ready for new tires. If you find irregular tread wear patterns, it means your tires need rotation and/or your wheels need to be realigned before you leave.

Belts and Hoses — Condition and Fittings

Look under the hood and inspect all belts and hoses to make sure they are in good shape with no signs of blisters, cracks, or cuts in the rubber. High summer temperatures accelerate the rate at which rubber belts and hoses degrade, so it’s best to replace them now if they show signs of obvious wear. While you’re at it, check all hose connections to make sure they’re secure. 

Wiper Blades — Wear and Tear on Both Sides


After the heavy toll imposed by winter storms and spring rains, windshield wipers are likely to be ragged from use and ready to be replaced. Like rubber belts and hoses, wiper blades are susceptible to the summer heat. Examine your blades for signs of wear and tear. If they aren’t in tip-top condition, get new ones before you go. 

Cooling System — Coolant Levels and Servicing

Carefully check your coolant level to make sure it’s adequate. If it’s time to have your cooling system flushed and refilled (or even nearly time), make sure it’s done now. On a long road trip in summer heat, you’ll want your cooling system functioning at peak performance to avoid the possibility of your engine overheating.

Fluid Levels — Oil, Brake, Transmission, Power Steering, Coolant and Windshield Washer Fluids

Periodically you’ll want to check your vehicle’s oil level. And as with coolant, if it’s time or even nearly time to have the oil changed, now would be a good time to do it. In addition, check the following fluid levels: brake, automatic transmission, power steering,

windshield washer and coolant. Make sure each reservoir is full and if you see any sign of fluid leakage, take your vehicle in to be serviced. 

Lights — Headlights, Brake Lights, Turn Signals, Emergency Flashers, Interior Lights, and Trailer Lights

Make sure all the lights on your vehicle are in working order. Check your headlights, brake lights, turn signals, emergency flashers and interior lights. Towing a trailer? Be sure to check your trailer lights including brake lights and turn signals too. Failure of trailer light connections is a common problem and a serious safety hazard.

Air Conditioning — AC Check

Check AC performance before traveling. If you’re traveling with someone sensitive to heat, you may also want to make sure your AC system is functioning properly. Lack of air conditioning on a hot summer day affects people who are in poor health or are sensitive to heat, such as children and seniors. If the air is not blowing cold, have the system repaired before you go because emergency on-the-road repairs can be more costly than those you plan in advance.
