How much light should be allowed through the side windows?

In Ohio, the law specifies that the side windows of a vehicle must allow at least 50% light transmittance. This regulation is in place to enhance visibility for both the driver and law enforcement. Having sufficient light penetration through the side windows helps ensure that the driver can see outside clearly and that others can see inside the vehicle. This contributes to overall safety on the road by minimizing blind spots and improving interaction with pedestrians and other drivers.

While a higher percentage of light transmittance could be beneficial in terms of visibility, the minimum standard set at 50% strikes a balance between light filtration for comfort and maintaining safety standards. Therefore, allowing 50% light through the side windows is the legal requirement in Ohio.
