North Dakota requires 50% VLT on front sides but both sedans and SUVs get any darkness on rear glass. The intense glare off snow in winter and flat open terrain in summer both make a case for tint even in a cold-climate state. The 50% front side limit is stricter than average but the open rear helps balance things out.

Front side windows need a minimum of 50% VLT. Back side windows require any darkness, and the rear window requires any darkness.
A first offense is typically $20 noncriminal. Repeat offenses can cost $20–$50. Fix-it tickets are available, giving you time to remove or replace the film.
Your car's factory glass already blocks some light (usually around 70-80% VLT). When you add tint film, the combined VLT is lower than the film alone. For example, 35% film on 75% factory glass gives you about 26% combined VLT. The calculator above does this math for you.
