Emergency Stop Signal

It means a signal to indicate to other road users to the rear of the vehicle that a high retardation force has been applied to the vehicle relative to the prevailing road conditions. The emergency stop signal shall be given by the simultaneous operation of all the stop or direction-indicator lamps fitted as described in corresponding paragraphs.

However, if any of the lamps of the emergency stop signal to the rear of the vehicle use filament light sources the frequency shall be 4.0 +0.0/-1.0 Hz.

-> The emergency stop signal shall operate independently of other lamps.

-> The emergency stop signal shall be activated and deactivated automatically.

-> The emergency stop signal shall be activated only when the vehicle speed is above 50 km/h and the braking system is providing the emergency braking logic signal defined in Regulations Nos. 13 and 13-H.

The emergency stop signal shall be automatically deactivated if the emergency braking logic signal as defined in Regulations Nos. 13 and 13-H is no longer provided or if the hazard warning signal is activated.
