The legally permissible darkness of window film applied to vehicles in the state is regulated to ensure visibility and safety. These regulations specify different allowable levels of light transmittance for front side windows, rear side windows, and the rear window. Light transmittance is measured as the percentage of light allowed to pass through the film and glass combined.
Adhering to these stipulations is crucial for vehicle owners to avoid potential legal penalties, including fines and the requirement to remove non-compliant film. Historically, these regulations have been implemented and adjusted to balance driver privacy with law enforcement’s need to clearly view vehicle occupants. Properly installed window film, within the prescribed limits, can also provide benefits such as heat reduction and glare mitigation, enhancing driver comfort.
