Understanding Windshield Inspection Regulations and Standards
Overview of Windshield Inspection Regulations
In the United States, the National Highway Traffic Safety Administration (NHTSA) sets the standards for windshield inspection. The Motor Vehicle Safety Act of 1966 established the NHTSA, which is responsible for ensuring that vehicles meet minimum safety standards. The Federal Motor Carrier Safety Administration (FMCSA) and the Department of Transportation (DOT) also play a crucial role in setting regulations for windshield inspection.
When it comes to windshields, the NHTSA sets the standards for the minimum requirements that a windshield must meet in order to be considered safe for driving. These standards include the size, shape, and materials used to make the windshield. The NHTSA also sets the standards for windshield wipers, defrosters, and other windshield-related components.

Windshield Inspection Requirements
The NHTSA requires that windshields meet certain inspection requirements in order to pass. These requirements include:
The windshield must not have any cracks or chips that are larger than 1 inch in diameter.
The windshield must not have any damage that affects the windshield wipers or defrosters.
Chip Size and Location: What Matters Most
When it comes to windshield chips, the size and location of the chip are critical factors in determining whether it will pass inspection. A chip that is smaller than 1 inch in diameter may be considered minor and may not require replacement. However, a chip that is larger than 1 inch in diameter may be considered major and may require replacement.
The location of the chip is also important. A chip that is located in a critical area, such as the driver’s line of sight, may be considered a major defect and may require replacement. On the other hand, a chip that is located in a non-critical area may be considered minor and may not require replacement.
Chip Size and Location: Examples and Cases
Here are some examples of how chip size and location can affect the outcome of a windshield inspection:
A chip that is 1.2 inches in diameter and located in the driver’s line of sight may be considered major and may require replacement.
