Emergency Brake Signal (Flashing Brake Lights)
The emergency brake signal flashes the brake lights or hazards during hard braking.
What is Emergency Brake Signal (Flashing Brake Lights)?
It warns following drivers. It is common in Europe. Hazards may turn on after a stop. The function is regulated in the EU and in other markets, with defined deceleration and speed thresholds. Some cars also flash the hazard lights automatically after an emergency stop to warn traffic behind. Drivers do not need to activate it, and it switches off as soon as the car accelerates again.
How it works
The system detects strong deceleration.
Why it matters for your car
It is automatic. Faults are rare.
