Dear Mr. Tanaka:

This responds to your FAX of August 4, 1991, to Ms. Delmas Johnson of this agency concerning Standard No. 208, Occupant Crash Protection. Your questions and the answers to each follows.

Is it true that the belt fastening law now goes into a part of the federal law?

The National Traffic and Motor Vehicle Safety Act authorizes NHTSA to issue motor vehicle safety standards that apply to the manufacture and sale of new motor vehicles and new items of motor vehicle equipment. The Federal requirements do not, however, regulate the use of vehicles. While there is no Federal requirement mandating safety belt use, a recent final rule will impose penalties on states which do not have both a safety belt and a motorcycle helmet use law by 1994. Currently, all the states and territories have some type of mandatory belt use law except Kentucky, Maine, Massachusetts, New Hampshire, North Dakota, and South Dakota.

Is it true that the cars with airbag do not need to perform "Roll Over Test"?

Passenger cars manufactured on or after September 1, 1989, are required to be equipped with automatic crash protection at the front outboard seating positions. "Automatic crash protection" means that a vehicle is equipped with occupant restraints that require no action by vehicle occupants. The two types of automatic crash protection currently offered on new passenger cars are automatic safety belts (which help to assure belt use) and air bags (which supplement safety belts and offer some protection even when safety belts are not used). The performance of automatic crash protection is dynamically tested, that is, vehicles equipped with automatic crash protection systems are required to comply with certain injury criteria as measured by test dummies in a barrier crash test at speeds up to 30 mph. In addition, the automatic crash protection must either meet the lateral and rollover crash protection requirements or have a Type 1 (lap) or Type 2 (lap/shoulder) seat belt assembly. A passenger car equipped with an air bag does not have to comply with the rollover test if it has a Type 1 or Type 2 seat belt at that position. To our knowledge, all vehicles currently being manufactured are certified to the automatic crash protection requirement by installing Type 1 or Type 2 seat belt assemblies.

A new Federal statutory requirement will make air bags and Type 2 seat belts mandatory in all cars and light trucks by the late 1990's. I am enclosing a copy of the recently published final rule implementing these requirements. These requirements will make the option of complying with the lateral and rollover crash protection requirements moot.

I hope you find this information helpful. If you have any other questions, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992.

Sincerely,

John Womack Acting Chief Counsel
