AS-1 line typically extends between 4 and 6 inches parallel to the top of your windshield. AS-1 designation line is typically marked by glass manufacturer on the top edge of your windshield.

Depending on vehicle, your AS-1 strip may already be tinted. In most states windshield tint must not have any reflectiveness, and illegal colors typically include blue and red.

Some state tint laws specify exact number of inches you are allowed to tint on front windshields. Other states define this windscreen area simply as an AS-1 line. Learn more about AS-1 Line.

Federal vehicle ID label found on driver's front door frame will tell you whether your vehicle is classified as passenger or multi purpose vehicle.

• Passenger vehicles include: sedan, coupe, convertible, station wagon, hardtop and hatchback vehicles.
• Multi-purpose vehicles include: SUV, pickup, van, truck, RV, trailer, bus and minibus.

In most states vehicles fall under these two categories.

Violating tint laws in New Hampshire is considered a violation, not a misdemeanor.

Under New Hampshire law (RSA 262:41 and the New Hampshire DMV’s Uniform Fine Schedule), window tint violations are treated as non-moving traffic infractions subject to general penalty fines:

• First Offense: $62.00 fine (plus any local surcharges or fees depending on the specific municipal enforcement).
• Subsequent Offense (within a calendar year): $124.00 fine.

Additional penalties & consequences:

• Inspection Failures: Driving a vehicle with illegal aftermarket tint will cause the car to fail its annual New Hampshire state safety inspection.
• Local Enforcement: Local police departments (such as in towns like Londonderry or Merrimack) may issue specific citations or escalate tickets depending on the darkness of the tint (e.g., very dark 5% or 20% tints).

The last meaningful legislative change to New Hampshire tint laws was made in 2024.
