NHTSA to keep TPMS warning light requirement

July 13, 2007

The National Highway Traffic Safety Administration (NHTSA) has decided to retain its requirement that tire pressure monitoring system warning lights initiate a 60- to 90-second flashing sequence when an air pressure problem is found.

The decision was made in respone to a request by the Alliance of Automobile Manufacturers. The group believed NHTSA had insufficiently addressed the issue in its final TPMS ruling, which was made in 2005.
