Quick FAQs
Under latest laws with increased fines in 2025, vehicles owners are liable for $300 to $550 fine for each separate offense. Business owners or installers who violate tint laws must pay from $700 to $1,200 for each separate offense.
Also introduced in 2025’s law amendment, drivers and passengers with tinted windows must always roll down windows when stopped by law enforcement. Failure is a noncriminal traffic infraction.
Visible light transmission (VLT) measures how much visible light passes through a vehicle window. Law enforcement often uses a tint meter device to measure VLT. However, tint meters are not always perfectly accurate, and readings can vary slightly due to the equipment or measurement conditions.
To account for these small differences, Hawaii allows a variance of 6% when measuring window tint. As tint meters are not 100% accurate, the tolerance should never be used to apply darker than legally permitted tint.
