TEXT: Dear Ms. Byron:

Thank you for your recent letter on behalf of your constituent, Mr. Joseph L. Ciampa, Jr., who received a citation from the Maryland State Police, Automotive Safety Enforcement Division, for noncomplying window tinting. You asked us to review Mr. Ciampa 's letter and provide you with our comments and appropriate information. I am pleased to have the opportunity to do so.

Mr. Ciampa suffers from diabetes, which makes his eyes extremely sensitive to sunlight. Because of this, the side windows on his passenger automobile apparently were tinted such that the tinted glazing no longer complied with State of Maryland requireme nts. There is no indication whether Mr. Ciampa did the tinting on his own or had an aftermarket business do it. According to Mr. Ciampa's letter, he was previously given a medical exemption by the State of Maryland that permitted him to drive with wind ows tinted differently than Maryland law permits. However, Mr. Ciampa stated that Maryland officials have now told him that the Federal government will not allow Maryland to grant any more medical exemptions. This information is inaccurate.

Some background information on the Federal requirements in this area may be helpful. Our agency, the National Highway Traffic Safety Administration (NHTSA) is authorized, under the National Traffic and Motor Vehicle Safety Act, to issue safety standards applicable to new motor vehicles and certain items of motor vehicle equipment. The safety standard that specifies performance and location requirements for glazing used in vehicles is Standard No. 205, Glazing Materials (49 CFR 571.205). These require ments include specifications for minimum levels of light transmittance (70 percent in areas requisite for driving visibility, which includes all windows in passenger cars). Under Standard 205 no manufacturer or dealer is permitted to install solar films and other sun screen devices in a new vehicle, without certifying that the vehicle continues to be in compliance with the light transmittance and other requirements of the standard.

Federal law does not permit States to grant any exemptions, including medical exemptions, from the safety standards. Thus, we assume that Mr. Ciampa's car as delivered to him complied with Standard No. 205's requirement for at least 70 percent light tra nsmittance in all of its windows, including the side windows that are now the subject of dispute.

The requirement that a car comply with all applicable safety standards applies only until the car is first sold to a consumer. After a vehicle is first sold to a consumer, any modifications to the vehicle's windows, including the tinting performed on th e side windows of Mr. Ciampa's car, are affected by section 108(a)(2)(A) of the Safety Act. That section prohibits any manufacturer, dealer, distributor, or repair business from "rendering inoperative" any device or element of design installed in a vehi cle in compliance with any safety standard. In the case of windows in a passenger car, this means that no manufacturer, dealer, distributor, or repair business could install a sun screen device or window tinting that would result in a light transmittanc e of less than 70 percent for any window of the car, or otherwise cause the car to no longer comply with the other requirements of Standard No. 205. Violations of this "render inoperative" prohibition can result in Federal civil penalties to the manufac turer, dealer, distributor, or repair business of up to $ 1000 for each noncomplying installation.

Again, Federal law does not permit States to grant any exemptions, including medical exemptions, from the "render inoperative" prohibition in Federal law. Thus, the State of Maryland does not have any authority to permit manufacturers, distributors, deal ers, or repair businesses to install tinting on the side windows of passenger cars if such tinting causes those windows to have less than 70 percent light transmittance. Instead, the manufacturer, distributor, dealer, or repair business that installed s uch tinting on Mr. Ciampa's side windows would be liable for the civil penalty discussed above.

Please note that Federal law does not affect vehicle owners. Vehicle owners may alter their own vehicles and operate them on the highways as they please, even if the vehicle's windows no longer comply with the requirements of Standard No. 205. Hence, n o provision of Federal law or this agency's regulations prevents Mr. Ciampa himself from tinting his side windows.

However, each of the individual States has the authority to regulate the modifications that may be made to vehicles by their owners and to establish requirements for vehicles to be registered or operated in that State. It would seem that the State of Ma ryland has exercised its authority to prohibit windows being tinted in the way that Mr. Ciampa's are. The wisdom and fairness of applying that prohibition to individuals with Mr. Ciampa's condition is something to be decided by the State of Maryland, no t the Federal government. Contrary to the statement in Mr. Ciampa's letter, we have never told Maryland or any other State how to administer their laws and regulations with respect to the operational use of vehicles in the State.
