AN ACT to amend and reenact subsection 4 of section 39-21-39 of the North Dakota Century Code, relating to motor vehicle window tint.

HB 1340 amends North Dakota's vehicle tint law to clarify light transmittance requirements for window tinting. It requires that front windshields and front windows allow at least 70% light transmittance (meaning the tint can't be too dark), while other windows must allow at least 35% transmittance. The law does not apply to rear windows if a vehicle has outside mirrors meeting standard requirements. This directly affects drivers who install window tint, ensuring visibility for safety while maintaining existing exceptions for rear windows with proper mirrors.
