NHTSA Calls on Motorists to Observe Vehicle Safety in Hot Weather

June 2, 2008

WASHINGTON - The National Highway Traffic Safety Administration (NHTSA) has urged motorists to take safety precaution before going out to drive in hot weather. NHTSA administrator Nicole Nason also advised vehicle drivers to check the condition of tires in their vehicles.

The agency issued the advisory in the light of rising incidents of serious vehicle crashes during summer and hot weather. According to studies conducted by the agency, the risk of crash during summer can be heightened by old, worn-out and under-inflated tires.

The research also showed that hot weather and overloading may subject tires to significant stress, especially if it is not properly inflated. Old tires are also subject to greater stress, which increases the likelihood of catastrophic accidents.

In addition, tire condition is also important and critical for vehicles prone to rollover, when tires fail, especially sport utility vehicles (SUV’s), pickups and other vehicles with higher center of gravity.

The agency further urged motorists to check tire pressure by using a tire gauge and following the manufacturers’ recommended pressures, which are found on the driver’s side door pillar or in the owner’s manual.

On the other hand, tire age can be determined by checking the identification number on the sidewall that begins with the letters "DOT". The last four digits represent the week and year the tire was manufactured.

To ensure safety, tires that are six to tern years old must be replaced based on the recommendation of tire and vehicle manufacturers. Consumers are also advised to check with their tire or vehicle manufacturer for specific guidance.
