Will a Cracked Windshield Pass Inspection in Mo?
Understanding Missouri’s Vehicle Inspection Regulations
In the state of Missouri, vehicle inspections are mandatory for all vehicles with a gross vehicle weight rating (GVWR) of 6,001 pounds or more. This includes cars, trucks, buses, and RVs. The Missouri Department of Revenue is responsible for enforcing the vehicle inspection regulations. The primary purpose of these inspections is to ensure that vehicles on the road are safe and meet minimum safety and emissions standards.
The Missouri vehicle inspection process involves a comprehensive examination of the vehicle’s brakes, suspension, steering, exhaust system, tires, and emissions control systems. The inspection also includes a visual examination of the vehicle’s windshield for any signs of damage or impairment.

According to Missouri law, a vehicle with a cracked windshield can pass inspection if the crack is less than 6 inches in length and does not compromise the driver’s view. However, if the crack is longer than 6 inches or obstructs the driver’s view, the vehicle will fail inspection.
Factors to Consider When Determining Whether a Cracked Windshield Will Pass Inspection
Size and Location of the Crack
The size and location of the crack on your windshield can play a significant role in determining whether it will pass inspection. If the crack is less than 6 inches in length and is located in an area that does not obstruct the driver’s view, it may be acceptable. However, if the crack is longer than 6 inches or is located in an area that affects the driver’s visibility, it may be considered a safety hazard and result in a failed inspection.
Some common locations where a crack may be more likely to be tolerated include the upper corners of the windshield, where it is less likely to obstruct the driver’s view. However, if the crack is located in the driver’s line of sight or obstructs the view in any way, it may be considered a safety hazard and result in a failed inspection.
It’s also worth noting that some insurance companies may have specific requirements or recommendations for windshield repair or replacement. If you’re unsure about whether your cracked windshield will pass inspection, it’s a good idea to check with your insurance company to see if they have any specific requirements or recommendations.
Driver’s View and Visibility
The primary concern when it comes to windshield cracks is whether they obstruct the driver’s view. If the crack is located in an area that affects the driver’s visibility, it may be considered a safety hazard and result in a failed inspection.
Some common signs that a windshield crack may be obstructing the driver’s view include:
- Distorted or blurry vision
- Visible cracks or chips in the windshield that affect the driver’s line of sight
- Cracks or chips that are located in the driver’s direct line of sight
Repair or Replacement Options
Repairing vs. Replacing a Cracked Windshield
When it comes to a cracked windshield, there are two main options: repair or replacement. The decision to repair or replace your windshield depends on the size and location of the crack, as well as your personal preferences and budget.
Windshield repair is a cost-effective option that can be completed in a matter of minutes. During the repair process, a special resin is injected into the crack to fill it and restore the windshield’s original strength and clarity. However, windshield repair is only suitable for small cracks that are less than 6 inches in length.
Windshield replacement, on the other hand, is a more extensive process that involves replacing the entire windshield with a new one. This option is more expensive than repair, but it provides a more permanent solution and can be completed in a matter of hours.
Some common signs that a cracked windshield may need to be replaced include:
- A large crack or chip that affects the driver’s view
- A crack or chip that is located in an area that is difficult to repair
- A windshield that is already showing signs of wear and tear
Cost Considerations
The cost of repairing or replacing a cracked windshield can vary depending on several factors, including the size and location of the crack, the type of windshield, and the location of the repair or replacement shop.
On average, the cost of windshield repair can range from $50 to $200, while the cost of windshield replacement can range from $200 to $1,000 or more. It’s worth noting that some insurance companies may cover the cost of windshield repair or replacement, so it’s a good idea to check with your insurance company to see what is covered.
Insurance Coverage and Requirements
Insurance coverage for windshield repair or replacement can vary depending on your insurance policy and the state you live in. In Missouri, some insurance companies may cover the cost of windshield repair or replacement, while others may not.
Some common insurance requirements for windshield repair or replacement include:
- A comprehensive insurance policy that covers windshield damage
- A deductible that must be paid before the insurance company will cover the cost of repair or replacement
- A requirement that the windshield be repaired or replaced by a certified repair shop
Understanding Missouri Vehicle Inspection Regulations
