FMVSS stands for Federal Motor Vehicle Safety Standards. They are standards set by the National Highway Traffic Safety Association relating to vehicle safety. A number of these standards set minimum requirements for windshield retention in vehicle accidents. Because the windshield is the most important safety restraint system in a vehicle, it’s critical that the windshield not come out in an accident. If that were to occur, the passenger compartment would be compromised, occupants could be ejected and the roof could collapse. Any of these scenarios would result in serious injury and possibly death. As a result, FMVSS must be adhered to with every windshield installation. The only way to meet these standards is by strictly following the vehicle manufacturers’ preferred installation methods. These include, performing full cutout procedures, utilizing OEM glass, applying the necessary primers and using only the approved adhesives that provide the proper safe drive-away times. FMVSS were created and are in place to save your life. Unfortunately, not all glass companies comply. It’s up to you to make sure your glass replacement company adheres to them. No one else will.
