TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letter of September 26, 1972, to Mr. Douglas W. Toms, in reference to our restraint systems and other standards for motor vehicles which may be purchased for use by law enforcement agencies.

Our Federal motor vehicle safety standards regulate new motor vehicles up to the sale to the purchaser. Accordingly, a law enforcement agency or other purchaser is not restricted by Federal law from removing or modifying required vehicle safety equipment once delivery is taken.

In the case of restraint systems, an aircraft or racing type safety harness with double shoulder belts would probably be superior to the standard automotive safety belts. However, our testing with human volunteers and baboons has demonstrated that the air cushion provides better crash protection than either aircraft or automotive safety belt systems. Thus, while we would not have reservations about replacing the standard automotive safety belts with the aircraft or racing type harness, we would not recommend replacing an air cushion system with any type of harness system. Rather, we would recommend relocating shotguns, communications, or other equipment to a location compatible with air cushion function if at all possible. In most cases, the vehicle manufacturers should be able to provide assistance in this regard.

I appreciate your interest in our motor vehicle safety programs. We would be pleased to provide whatever advice or assistance we may be able to give in assuring that law enforcement officers are afforded the safest vehicles suitable for their planned application.

SINCERELY,

DEPARTMENT OF CALIFORNIA HIGHWAY PATROL

September 26, 1972

File No.: 1.A2711.A997

Douglas W. Toms, Administrator National Highway Traffic Safety Administration U. S. Department of Transportation

Dear Mr. Toms:

There are few who are more concerned with highway safety than the members of the California Highway Patrol. The members of this Department spend most of their waking hours striving for the reduction of injuries and deaths on the roadways of California. Certainly Departmental policy has supported all governmental regulations aimed at the reduction of highway accidents. However, some present and proposed automotive design features hinder the effectiveness of the traffic officer in performing his duties. In fact, some regulations will actually result in a reduction of safety for the patrolman or police officer.

A restraint system which will slow an officer's exit from or entry into the car can be dangerous in some situations. Could not law enforcement agencies be allowed some leeway in the ordering of their cars? An aircraft-type quick release belt/harness arrangement would be effective yet would not create the problems of entry and exit inherent to the proposed sequential system to be introduced on 1974 model cars.

Shotguns are presently mounted in a vertical position to the right of the transmission hump and are attached to the dash. The vertical mounting provides visibility of an enforcement item, the muzzle is aimed in the safest direction, and the near center location provides accessibility to each front seat occupant. If the manufacturers supply air bags to comply with passive restraint regulation, will qualified law enforcement agencies be allowed to deactivate the system until the car is sold following its useful life? The convenient and safe installation of the shotgun and communications equipment will be most difficult in a car equipped with an armed air bag system.

It would seem that some consideration must be given to the needs of law enforcement agencies. Exemptions would not be requested just for the sake of reducing problems but rather in those few instances where a design requirement in the name of occupant safety actually increases the hazard to a police officer on duty.

The problems heretofore related are only a few of the many which face those who must use basically standard production automobiles for law enforcement adaptation. It is hoped that some action can be taken in those instances where regulations may actually make the car more dangerous and ineffective for enforcement work.
