Radar Detectors in North Carolina: Illegal for All Vehicles

The Law: Clear Prohibition

Under North Carolina General Statute § 20-138.1(c), it is unlawful to operate a motor vehicle on any highway or public vehicular area while equipped with a radar detector (or laser jammer). This applies to all vehicles — passenger cars, commercial trucks, motorcycles, out-of-state vehicles.

Penalties

• Infraction: Not a misdemeanor; no license points.
• Fine: Up to $100 + court costs (~$190 total).
• Seizure: Officer may seize the device as evidence; returned after adjudication.

Exceptions

• Law enforcement vehicles.
• Commercial vehicles >26,001 lbs GVWR engaged in interstate commerce — federal law (49 CFR 392.71) prohibits radar detectors in these vehicles nationwide, but NC law does not exempt them; they are doubly prohibited.

No exception for GPS-based camera/red-light alerts (e.g., Waze, Garmin database) — those are legal. Only active RF/laser detection/jamming is banned.

Neighboring States Comparison

• Virginia: Illegal (only other state + DC with total ban).
• South Carolina, Georgia, Tennessee: Legal for passenger vehicles.
• Federal: Illegal in commercial vehicles >10k lbs interstate (49 CFR 392.71). Illegal on all military bases.

Practical Advice

• If driving into NC (I-95, I-85, I-77, I-40, US-74, etc.), remove and stow your radar detector before crossing the state line.
• Laser jammers / "shifters" are also illegal (same statute).
• Radar detector detectors (VG-2, Spectre) are used by NC State Highway Patrol.
