No, radar detectors are illegal for use in Massachusetts vehicles. State law prohibits the operation of any device designed to detect police radar signals, classifying them as prohibited equipment under MGL c. 90 § 19B. Violations carry fines up to $250 and potential equipment confiscation. Local enforcement by the Massachusetts State Police and municipal departments remains consistent, with no 2026 regulatory shifts altering this prohibition.
Key Regulations for Radar Detectors in Massachusetts
- Statutory Ban: MGL c. 90 § 19B explicitly bans the use, possession, or operation of radar detectors in vehicles on public roads. The law applies to all drivers, including commercial operators.
- Enforcement Practices: The Massachusetts State Police Traffic Division and local law enforcement agencies actively cite violators, with penalties enforced through district courts statewide. Confiscation of devices is discretionary but common in repeat offenses.
- Exemptions: No exemptions exist for commercial vehicles, out-of-state drivers, or personal use. Even passive detection devices (e.g., GPS-based alerts) may be scrutinized under broader “distraction” or “obstruction” statutes if deemed to interfere with law enforcement operations.
