"Dear Ms. Stewart: This responds to your letter of October 16, 1992, t this office regarding the installation of a 'silent monitor' on school buses. You stated in your letter that you made a presentation to Mr. Maurice Hicks and Mr. Rich Van Iderstine of this agency at a meeting on October 2, 1992, and you asked how our standards apply to installation of this device on school buses. You described the silent monitor as a six-inch cube of welded steel designed to house a video camera to monitor the interior of school buses. You explained that the device is installed in the interior access panel above the bus windshield facing the passenger compartment. The box protrudes into the interior of the bus by three to four inches. The front of the box, which swings open for installation of a video camera, contains a reflective solar glass window to prevent glare on the inside of the box. By way of background information, NHTSA does not provide approvals of motor vehicles or motor vehicle equipment. Under the National Traffic and Motor Vehicle Safety Act (Safety Act), it is the responsibility of the manufacturer to ensure that its motor vehicles or equipment comply with applicable Federal safety standards. The following represents our opinion based on the facts provided in your letter. NHTSA does not have any safety standards specifically covering silent monitors. However, it is possible that the installation of a silent monitor could affect the compliance of a vehicle with some safety standards. All new motor vehicles manufactured for sale in the United States must be certified by their manufacturers as complying with the applicable Federal motor vehicle safety standards. If your silent monitor is installed in a new school bus prior to its first sale to a customer, the person making the installation would be considered a vehicle alterer. Under our certification regulation (49 CFR Part 567), a vehicle alterer must certify that the vehicle as altered continues to comply with all applicable Federal motor vehicle safety standards. Manufacturers, distributors, dealers, or motor vehicle repair businesses modifying a used vehicle are prohibited by Section 108(a)(2)(A) of the Safety Act from knowingly rendering inoperative any safety device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard. Thus, if your silent monitor is installed in a used school bus, any businesses, including your own, making such installations cannot render inoperative the vehicle's compliance with any of our standards. We also note that manufacturers of motor vehicle equipment have responsibilities under the Safety Act regarding safety defects. Under Sections 151, et seq., of the Safety Act, such manufacturers must notify purchasers about safety-related defects and remedy the product free of charge. In order to determine how installation of your silent monitors could affect the compliance of school buses with applicable Federal safety standards, you should carefully review each standard, including but not limited to those addressing school bus body joint strength, crash protection, and windshield intrusion. In that regard, I am enclosing for your information a fact sheet entitled Information for New Manufacturers of Motor Vehicles and Motor Vehicle Equipment, and a booklet entitled Federal Motor Vehicle Safety Standards and Regulations. As indicated above, you stated that your silent monitor would be installed in the interior access panel above the bus windshield facing the passenger compartment. Given the added weight that would be on the panel, we suggest that you carefully evaluate whether additional securement of the panel is needed to ensure that the panel and silent monitor do not come loose during a crash. We also note that the silent monitor appears to have sharp edges. You may wish to consider adding padding to prevent injury to an occupant who comes in contact with the monitor. I hope this information is helpful. If you have any further questions, please feel free to contact Walter Myers of my staff at this address or at (202) 366- 2992. Sincerely, Paul Jackson Rice Chief Counsel Enclosure";
