Tinted windows: the law, yes, but for whom?

Tinted car windows are everywhere on the island: a common practice, an offence that has become invisible. The regulations exist, they are clear, and so are the penalties. So why do we feel that they are not really being enforced?

In some vehicles, it's a complete mystery. Outside, it's an offence that no longer shocks anyone. Tinted windows are becoming increasingly common, and not just at the rear. Some cars have such high levels of opacity that it is impossible to tell if there is only one driver on board. This situation raises questions about both road safety and compliance with the law.

What the law says

However, French regulations are unambiguous. All windows in the driver's direct field of vision, including the windscreen and front side windows, must allow at least 70% of visible light to pass through, i.e. a maximum opacity of 30%. Any vehicle exceeding this threshold exposes the driver to a fine of €135 and a loss of 3 points on their driving licence, if the latter was not issued by the Collectivité of Saint-Martin. During technical inspections, non-compliant vehicles are simply refused, with a mandatory re-inspection. Please note: rear windows are not subject to any particular restrictions, provided that the vehicle is equipped with functional exterior mirrors.

Two rooms, two atmospheres

The Dutch part of the island has settled the issue in its own way. The police regularly carry out targeted operations: removing non-compliant films, immobilising offending vehicles, and making arrests. The checks are visible, unapologetic and intended to be a deterrent. Is the same rigour applied in the French part of the island? Are checks carried out? Are operations planned? When asked about this, the local authorities did not respond to our requests. In the absence of a response, the question remains unanswered, and the windows remain opaque.
