Big Rigs to Blink SOS Lights? FMCSA Seeks Truck Safety Input
Published Date: 8/26/2025
Notice
Summary
Emergency Safety Solutions wants permission to use a special flashing light system on big trucks during emergencies, making their warning lights pulse faster to grab attention. This change affects truck drivers and safety rules, and the government is asking for public feedback before deciding. If approved, this could last five years and help keep roadside workers and drivers safer without extra costs.
Analyzed Economic Effects
1 provisions identified: 1 benefits, 0 costs, 0 mixed.
Faster Flashing Truck Rear Lamps Allowed
If you operate or own a commercial truck, the applicant asks to let rear clearance, identification, and brake lamps pulse faster during emergency stops or breakdowns — increasing from the standard 1–2 hertz to 4–5 hertz. The request would exempt certain rules about placing warning devices, the requirement that exterior lamps be steady burning, and requiring specific types of warning devices, and the exemption (if granted) would run for five years.
