Dear Mr. Carraway:

This responds to your letter in which you follow-up on our earlier correspondence regarding belt minder systems. In your recent letter, you requested that the agency require vehicles to be equipped with a belt minder system which relies on a voice synthesizer to provide an audible alarm. As explained below, the agency does not have authority to require a system as you have described.

In your letter, you requested that the agency require vehicles to be equipped with a belt-minder system developed by your company. You explained that the system would transmit a message through a vehicle’s audio system when a vehicle’s ignition is turned to the “on” position. Additionally, you stated that your system would use a voice synthesizer to state, “Thank you for fastening your seat belt.” You further explained that the duration of the message would be 4 or 5 seconds, and would repeat after a period of approximately 100 seconds. From your letter, it appears that the audible warning would sound regardless of whether the safety belt at the driver’s seat is buckled.

I want first to thank you for your continued interest in motor vehicle safety. As explained in our previous letter to you, Congress has provided the agency with specific direction with respect to certain types of vehicle-based safety belt incentives. 49 U.S.C. § 30124 states that:

A motor vehicle safety standard … may not require or allow a manufacturer to comply with the standard by using a safety belt interlock designed to prevent starting or operating a motor vehicle if an occupant is not using a safety belt or a buzzer designed to indicate a safety belt is not in use, except a buzzer that operates only during the 8-second period after the ignition is turned to the “start” or “on” position. (Emphasis added.)

Under this provision, the agency is prohibited from establishing a standard based on the system you described. Specifically, the agency is prohibited from requiring a belt minder system that sounds after the initial 8-second period. As your system has a second audible alarm 100 seconds after a vehicle’s ignition is turned to the “on” position, a standard mandating your system would not comply with the congressional directive.

While the agency is unable to mandate your system, we continue to encourage vehicle manufacturers to consider voluntarily introducing belt-minder systems and other innovative technologies that could increase seat belt use in ways acceptable to their customers. As explained in our previous letter to you, manufacturers may provide a voluntary audible signal that sounds after the 8-second period specified in S7.3 of Federal Motor Vehicle Safety Standard (FMVSS) No. 208, Occupant crash protection, so long as they provide some means for differentiating the voluntarily provided signal from the required signal. Further, i n a previous interpretation letter to MMC Services, we stated that an audible “voice” signal would be permitted under the standard (January 13, 1981; copy enclosed).

However, we have concerns with a system such as you described, in which the audible signal operates regardless of whether an individual is buckled-up. Under your system, an occupant that has not fastened his/her safety belt would still be “thanked” for buckling-up. This may minimize the incentive to buckle-up that a belt-minder system is intended to provide. Further, it could both confuse and aggravate drivers and passengers because an occupant would receive the same signal no matter what action is taken.

If you have any further questions, please contact Chris Calamita of my staff at (202) 366-2992.

Sincerely,

Jacqueline Glassman
Chief Counsel
