Damaged Windshield or Rear Window: What Does the Law Say?

Driving with a cracked windshield or damaged rear window is more common than you might think. Thermal shock, flying gravel, attempted theft... the causes can be multiple. But beyond the visual discomfort or the safety risk, the question arises: is it legal to drive with damaged glass? And what could be the consequences? YES GLASS explains what French law says on the subject, and tells you the best course of action to adopt to avoid trouble.
1. A Damaged Windshield: What Does the Highway Code Say?
The windshield is an essential safety element . It not only guarantees good visibility, but also contributes to the structure of the vehicle and the proper functioning of the airbags.
According to article R316-3 of the Highway Code :
"Every motor vehicle must be equipped with devices allowing sufficient visibility for the driver."
An impact or crack in the driver's field of vision is therefore considered an offense if:
- The impact exceeds 2.5 cm (about the size of a 2 euro coin)
- The impact is located in the direct field of vision
- The windshield has more than 2 visible impacts
🚨 In the event of an inspection, you risk:
- A fixed fine of €68
- A second visit to the technical inspection
- Possible immobilization of the vehicle in the event of immediate danger
💡 YES GLASS offers you a rapid intervention that complies with manufacturer standards to avoid any penalties.
2. And for the Rear Window: What are the Legal Risks?
The rear window allows the driver to see what is happening behind the vehicle , especially when reversing. It is therefore also subject to legal requirements.
Even though the law does not mention the rear window as strictly as the windshield, a window:
- Crack
- Partially broken
-
Covered with a deteriorated or opaque film
may constitute an offense under the heading of reduced visibility and non-compliance of the vehicle .
🚨 Possible consequences:
- Refusal of technical inspection
- Fine for traffic checks
- Loss of rear visibility which may incur your liability in the event of an accident
💡 A damaged rear window cannot be repaired, it must be replaced , because it is made of tempered glass.
3. Insurance and Glass Breakage: What You Need to Know
If you have insurance with glass breakage cover , you can benefit from:
- Free replacement or repair (depending on the glass concerned)
- A refund without excess , according to the terms of the contract
- Rapid support by approved professionals
🚗 With YES GLASS:
- No advance payment (if your contract includes glass breakage cover)

4. Technical Inspection and Damaged Glass
During the technical inspection , the windows are carefully checked.
Windshield case:
- An impact in the field of vision = mandatory re-inspection
- A through crack = vehicle not compliant with safety regulations
Rear window case:
- If the lens is cracked or broken = reason for major failure , therefore a follow-up inspection is required
💡 Don't wait until the inspection date to take action: YES GLASS saves you additional costs by replacing the glass before the due date.
5. Why Should We Not Wait to Act?
Driving with damaged glass, even slightly, can quickly deteriorate:
- A small crack can become larger due to vibration or cold
- A weakened window can suddenly shatter , especially in high heat.
- In the event of an accident, you may be held liable if non-compliant glazing played an aggravating role
📍 And above all, it is prohibited by law !
