WASHINGTON - Two developments late last week make clearer what automakers and suppliers must do to comply with the federal safety law passed after the Firestone tire disasters.
First, Bush administration officials said they had largely resolved their differences over a rule requiring tire pressure monitors on new cars and trucks. It is to be completed within weeks and effective in two years. Automakers will be allowed to install systems with sensors in each wheel or systems that piggyback on antilock brakes.
Second, the National Highway Traffic Safety Administration on Friday, March 1, issued proposed rules to implement the law's mandate that tire testing and performance standards be improved.
NHTSA said it is concerned about costs, estimated at $282 million a year.
