No. Radar detectors are illegal in Thailand under the Land Traffic Act B.E. 2522 (1979) and Radio Control Act B.E. 2558 (2015), enforced by the Royal Thai Police and National Broadcasting and Telecommunications Commission (NBTC). Possession or use risks fines up to ฿4,000 or confiscation, with stricter penalties for commercial distribution.
Key Regulations for Radar Detectors in Thailand
- Prohibition under Land Traffic Act: Section 47 explicitly bans devices that interfere with or detect police radar, classifying them as “illegal communication equipment.”
- NBTC Radio Control Act: Operating unlicensed radio-frequency devices (including radar detectors) violates Sections 27–28, subjecting users to NBTC enforcement actions.
- 2026 Compliance Shifts: The NBTC’s upcoming Radio Spectrum Management Master Plan will tighten penalties for unlicensed devices, including mandatory device registration for exempted categories (e.g., emergency services).
Violations are prosecuted under criminal rather than administrative law, with police empowered to seize equipment during traffic stops. Exceptions exist for licensed military or government use, but civilian ownership remains prohibited. Travelers should note that rental car companies may prohibit detectors under Thai law, risking additional contractual penalties.
