No. Radar detectors are illegal for all vehicles on Hawaii’s public roads. The state prohibits their use under Hawaii Revised Statutes §291-11.5, enforced by the Department of Transportation and county police departments. Violations may incur fines up to $300, with repeat offenses escalating penalties.
Key Regulations for Radar Detectors in Hawaii
- Statewide Ban: HRS §291-11.5 explicitly prohibits the possession or use of radar detectors in vehicles operating on public highways, regardless of vehicle type.
- Commercial Vehicles Prohibited: Federal Motor Carrier Safety Administration regulations align with Hawaii’s ban, applying to all commercial motor vehicles, including rental trucks and tour buses.
- Enforcement & Penalties: County police departments (e.g., Honolulu Police Department) issue citations, with fines ranging from $100 to $300 for first-time offenses. Subsequent violations may lead to higher fines or mandatory court appearances.
Local enforcement agencies, including the Hawaii Department of Transportation’s Traffic Safety Section, conduct periodic crackdowns, particularly in high-traffic corridors like H-1 and Nimitz Highway. The 2026 legislative session may introduce stricter penalties, including potential license suspension for repeat offenders. Out-of-state drivers are not exempt; rental car companies may impose additional administrative fees for violations.
