Safety Standards


Don’t take chances with a broken windshield

It is imperative that a broken windshield be replaced properly. All of the following Federal Motor Vehicle Safety Standards (FMVSS) must be met for a proper installation and Auto Glass of America will guarantee that they will be.




Federal Motor Vehicle Safety Standards

The Federal Motor Vehicle Safety Standards (FMVSS) that are referenced in the National Traffic and Motor Vehicle Safety Act of 1966 are special requirements for the OEMs to follow to insure a safe vehicle. There are hundreds of these standards that each OEM must meet, from mechanical to structural strength. For auto glass installation, you can concentrate on these:

FMVSS 205 (Glazing Materials)

This standard governs all glazing materials for the vehicle including high penetration resistance windshields. The standard was implemented in 1968 with the goal of preventing occupant penetration through the windshield and projectile intrusion into the passenger compartment.


This standard describes the safety standards regarding occupant crash protection. Although this standard primarily describes the tests for the seat belts and their use, it does mention airbags as an option for a passive restraint system. The government will probably expand this standard to include more detailed requirements regarding both driver’s side and passenger’s side airbag deployment.

FMVSS 212 (for passenger vehicles and trucks under 10,000 lbs.)

This standard is a windshield retention test. The standard requires every model passenger vehicle weighing less than 10,000 pounds to be tested by crashing it into a fixed barrier at 30 miles per hour. The windshield must have a minimum retention around the periphery of its edges of not less than 50 percent on each side of a longitudinal centerline for vehicles equipped with passive restraint systems and 75 percent for vehicles without passive restraints. The vehicle being tested is equipped with two 50th percentile dummies, located in the two forward passenger seats.

FMVSS 216 (for passenger vehicles and trucks under 10,000 lbs.)

The standard is a roof crash resistance test. The test forces a rigid block downward on the side of the forward edge of the passenger vehicle (not a convertible) roof. The windows must be closed and the doors locked. The force increases until it reaches a force 1½ times the vehicle weight or 5,000 pounds, whichever is less. The resistance force must be reached before the block moves downward five inches.

The aftermarket does not have the working conditions of the OEMs, but the ARG industry does meet the FMVSS requirements in a wide variety of working conditions. Although neither the adhesive nor windshield retention is specifically mentioned in FMVSS 216, the windshield might help to support the roof in some makes and models, thus requiring a certain strength of the adhesive used.


This standard specifies the requirements for the performance and location of exterior rearview mirrors. It applies to passenger cars, multipurpose passenger vehicles, trucks, buses, school buses, and motorcycles. Basically, this standard:

  • Makes it illegal to replace a convex mirror with a non-convex mirror if the overall size is less than 19.5 square inches in area.
  • Requires permanent and indelible marking on the rearview mirror.
  • Requires the statement that “objects in mirror are closer than they appear.”
