TITLE: FMVSR INTERPRETATION

TEXT: Thank you for your letter of November 2, 1971, to Secretary Volpe, in reference to our occupant crash protection program.

I am enclosing a copy of the proposed amendment to Federal Motor Vehicle Safety Standard No. 203, Occupant Crash Protection, which would allow an ignition interlock system as an option to front seat passive systems from August 15, 1973, to August 15, 1975. I am also enclosing an explanatory press release.

In regard to your question number one, we require that the interlock system be acquentially linked to the seat switch, such that a person would have to fasten the belt, after being seated, each time he attempted to start the car.

With regard to your questions numbers two and three, the National Traffic and Motor Vehicle Safety Act of 1966 gave us authority to set safety requirements for new motor vehicles. Under this authority, we cannot prevent an owner from tampering with or modifying his vehicle once purchased. Such authority would indeed require additional Congressional legislation. However, the Highway Safety Act of 1966 permits us to establish standard which serve as guides for individual state safety programs. It is possible for the states to(Illegible Words) such anti-tampering regulations. We will certainly be considering such actions once we determine the magnitude and effect of tampering in vehicles which have been produced to meet the Federal standards.

In regard to your question number four, I am not presently aware of any plans by insurance companies to require seat shoulder belt usage in order to be(Illegible Word) for collision coverage in case of an accident.

You are certainly correct in that the present shoulder belt designs often make it difficult to have a properly adjusted shoulder belt and still be able to have a reasonable degree of freedom of movement during normal vehicle operation. We are attacking this problem on two fronts. Federal Motor Vehicle Safety Standard No. 101, Control Location, Identification and Illumination -- Passenger Cars, requires that most critical controls, such as the steering wheel, headlamp switch, etc., be within reach by a person restrained by a lap and shoulder belt system. The present version of this standard does not include the parking brake or its release mechanism. The second action, which we are taking, is to propose a requirement that shoulder belt systems in cars manufactured after August 15, 1973, shall be equipped with inertia reel retractors that allow freedom of movement except in a crash situation.

I appreciate your thoughtful comments and your intense interest in our motor vehicle safety programs. It is very helpful to our efforts to improve highway safety when concerned citizens, such as yourself, take the time to bring their comments and suggestions to our attention.

November 2, 1971

Honorable John A. Volpe Secretary, Department of Transportation

SUBJECT: Automobile Safety/Air Bags

I have been waiting to write you until I had time to think a bit more about your recent decision to defer the requirement for installation of air bags in the front seat of cars from August 1973 to August 1975.

I have followed the development activities of the air bags and am aware of certain shortcomings such as their present inability to protect occupants from side collisions and "second collisions." It is my understanding that the noise problem (while very loud) was tolerable, especially preferable to death if the air bag saved the person's life. I also have no doubt that suitable sensors can be developed (if they are not already available) which do not trigger accidentally.

I must add that I feel DOT has been negligent in not pushing the development of the passive air bag system with greater effort so that your decision could not be partially based on the lack of development of the device. With over 50,000 human lives being lost each year, too much is at stake for such a situation to exist. As a former resident of Massachusetts, I remember (and I am sure you remember) the "Boston Strangler" which I believe accounted for some eight lost lives and caused considerable furor. The entire Boston community was alarmed. You seem to pay less attention to the loss of 50,000 lives by failing to provide a passive restraint system but instead provide what I believe is a seat/shoulder belt system that can easily be by-passed with some wiring jumpers.

Now for some constructive comments: I am aware that the new alternatives to the air bags are the seat/shoulder belts with a switch built in the seat so the car will not start unless the seat belt/shoulder strap is fastened. I believe that the seat/shoulder belt system is an excellent system (even better than air bags) if you can require that all persons use them at all times.

In order to understand better your new ruling, I would appreciate receiving answers to the following specific questions:

1. What means are being taken to prevent a person from merely by-passing (or shorting out) the seat switches which would simply negate your recent decision?

2. Are you now or do you plan to push for a federal law that prevents tampering (by-passing) the seat switch and which will make it mandatory that the front seat occupants wear these devices at all times while the car is in motion?

3. Does the federal government (DOT) have the perogative to issue an anti-tampering regulation, or does it require a federal law passed by Congress, or will it require each state to take separate action?

If this is a law or regulation that must be passed by each state, what measures are you encouraging the states to take in order to continue to receive certain federal highway funds?

4. Do you know of any plans by insurance companies to require occupants to wear seat/shoulder belts in order to be reimbursed for collision coverage in case of an accident?

Due to the very small acceptance by the public of seat/shoulder belts installed in cars since 1968, I believe that unless you take some very specific actions such as mentioned in items 1-4 above, the public will continue to refuse to employ the belt system and you likely will not make your agency goal of cutting automobile fatalities in half by 1980.

Now that you have taken the seat/shoulder belt route, I encourage you to see that the automobile manufacturers correct certain present obvious deficiencies in these systems which you should never have allowed to exist. The deficiencies are as follows:

In many cars (I regularly use rental cars) I cannot reach the emergency brake release after latching the shoulder belt, nor can I reach the open car door to close it. I quite often leave the car door open while I figure out the particular belt system and get it properly adjusted. I have a 1968 Delta 88 Oldsmobile in which neither of these deficiencies exist so it is certainly possible to design around this problem. I believe the inability to

reach the emergency brake release can be considered a safety hazard since one might find it necessary to perform a modulated stop if the dual braking system should suffer a catastrophic failure.

I would appreciate receiving detailed information on what specific actions you have taken to overcome the deficiencies listed above.

I also would appreciate receiving a copy of the latest regulations that spell out the requirements of the various seat/shoulder belt or passive restraint systems.

I will continue to support a strong and broad-based automobile/highway safety program. The tremendous loss of life, suffering, and monetary losses of car accidents are so large that anything short of a most serious effort on your part to correct this national problem would be totally unfair to all citizens.
