Can you drive with a cracked windshield ?
Because it is a source of insecurity for the driver and their passengers, as well as for other road users, including pedestrians, a damaged windshield can lead to a possible fine, depending on the extent of its deterioration, potentially resulting in a class 4 penalty. The law stipulates that "all windows" of a motorized vehicle must be sufficiently resistant to foreseeable incidents of normal traffic, as well as atmospheric and thermal factors, chemical agents, and abrasion"" (Article R316-3 of the Highway Code). The text adds that a car must be designed or equipped in such a way "that the driver's field of vision, to the front, right, and left, is sufficient for safe driving."
The cost of the financial penalty is 135 euros if the fine is fixed, and up to 375 euros in the case of an increased fine (95 euros if it is reduced).
The assessment of the infraction is based notably on the rules prevailing during the vehicle's technical inspection: from now on, the examination is carried out in the "visibility zone" of the windshield, meaning the very large area swept by the windshield wipers. An impact with a diameter larger than a two-euro coin, and any crack longer than 30 cm within this perimeter, especially if located at the driver's eye level, constitutes a "major defect." This finding will require a reinspection within 2 months.
Is it dangerous to drive with a cracked windshield ?
The answer is yes. Besides protecting the driver from projections, the windshield is an element that contributes to the vehicle's stability, particularly through its ability to withstand the dynamic pressure of the air. It also helps reinforce the mechanical strength of the bodywork, with which it forms a cohesive unit. Thus, damaged glazing at the front or rear weakens the very structure of the car and jeopardizes the safety of its user in the event of a violent impact.
Another risk obviously concerns reduced visibility while driving. The slightest crack in the windshield obscures potential obstacles on the road and increases the risk of an accident. The danger is even greater when the crack is in the driver's central field of vision, directly in front of them. By reflecting external light, it can also impair the driver's perception and become a focal point that diminishes their alertness and responsiveness.
