Most modern car windows have a subtle factory tint, even without third-party tint. The factory tint is typically very light and works to guard the window construction adhesives and materials from UV damage. This factory tint usually meets legal window tint limits in Ontario California but does not give significant heat rejection, glare reduction, or privacy benefits like additional tint. For additional tinting in Ontario California, consider the combined Visible Light Transmission (VLT) of the factory and aftermarket tints to confirm compliance with window tint laws. Some cars, such as Tesla, already have a factory-installed subtle tint in the glass.

If you need an exception for a medical reason, check the current rules with the responsible state authority before selecting film.
