Is Laser Jammers Legal in California After the 2026 Policy Reforms?

Yes, laser jammers occupy a legally ambiguous space in California, but their use is effectively prohibited under existing statutes.

Laser jammers—devices designed to disrupt police LIDAR speed detection—are classified as illegal interference with law enforcement equipment under California Vehicle Code § 28150. The California Highway Patrol (CHP) and local agencies enforce this prohibition, citing public safety risks. A 2023 amendment to § 28150 expanded penalties to include misdemeanor charges and fines up to $1,000, with potential vehicle impoundment for repeat offenses. Federal regulations under 49 U.S.C. § 502 prohibit tampering with vehicle safety equipment, further complicating interstate use. While no 2026 compliance shifts are imminent, enforcement has intensified in high-incident corridors like Los Angeles and San Francisco.

Key Regulations for Laser Jammers in California
