Severity: Few Restrictions · Light Restrictions · Some Restrictions · Significant Restrictions · Heavy Restrictions
Window Tint Limits
The visible-light-transmission percentage each window may be tinted to, which differs for the windshield strip, front sides, rear sides and back glass, plus reflectivity caps, the medical-exemption process, and how the tint is measured at inspection or roadside.
Underglow & Auxiliary Lighting
Which aftermarket light colours and placements are legal on a moving vehicle, the near-universal ban on forward-facing red and on blue light reserved to emergency vehicles, flashing and oscillating restrictions, and whether underglow may be lit in motion or only when parked.
Studded Tire & Chain Rules
The calendar window during which studded tires are permitted, the states that ban them year-round, stud material and projection limits, and the chain requirements that apply when a mountain pass or highway is placed under a traction restriction.
Lane Splitting & Filtering
Whether a motorcycle may ride between lanes of traffic, the newer lane-filtering statutes that permit it only at low speed and at a stop, the speed differentials written into those laws, and the states where it remains unlawful or simply unaddressed.
Plate Covers & Obstruction
Whether a licence plate may sit behind a clear cover or frame at all, the rules against obscuring the state name, registration stickers or any character, plate-flipping and reflective-spray prohibitions, and mounting height and angle requirements.
Dash Cam & Windshield Mounting
Where a camera, phone mount or GPS unit may legally sit on the windshield, the size and corner-placement allowances states carve out of their windshield-obstruction statutes, and the separate audio-consent question when a dash cam records passengers.
