What is the minimum light transmission percentage allowed for tinted windows?

In North Carolina, the minimum light transmission percentage allowed for tinted windows is set at 35%. This means that the tint must let at least 35% of light pass through the window. This regulation is designed to ensure visibility for both the driver and law enforcement, as overly tinted windows can obstruct the view into the vehicle and create safety concerns.

The specific requirement of 35% balances the benefits of window tinting, such as reducing glare and heat, with the need for safety and security. Ensuring a certain level of light transmission helps law enforcement officers identify occupants in vehicles during traffic stops and contributes to overall road safety.

While options with percentages lower than 35%, such as 25%, 30%, and higher than 35%, such as 40%, do not meet the legal requirements established in the state, the selection of 35% aligns with North Carolina's motor vehicle regulations regarding window tinting. Understanding these regulations is crucial for compliance and avoiding potential penalties.
