Ohio law specifies restrictions on the darkness and reflectivity of aftermarket window tinting. These regulations exist to ensure driver visibility and safety. The permissible darkness is measured by Visible Light Transmittance (VLT), which indicates the percentage of light allowed to pass through the tinted window. For example, a lower VLT percentage signifies a darker tint.
Adherence to these regulations promotes safer driving conditions by preventing excessively dark window tints that can obstruct the driver’s view, particularly at night or in adverse weather. Furthermore, compliance helps law enforcement officers easily identify vehicle occupants, contributing to overall public safety. Historically, regulations evolved due to concerns about traffic accidents and officer safety related to heavily tinted windows.
