AI gone mad, I do wish people would look up regulations without SHOUTING AI!
“The regulation ECE R13H (as my previous comment) mandates that if the rate of deceleration reaches a specific threshold, the vehicle must signal its intent to slow down. This threshold is typically set at a rate of deceleration equivalent to light conventional braking, often around [latex]1.3 meters per second squared (m/s^2) [/latex], which is approximately [latex]0.13 g [/latex] of force. If the regenerative braking force alone causes the car to slow down at or above this intensity, the brake lights must turn on. This regulation ensures that the energy-saving benefits of regeneration do not compromise established road safety protocols.”
Approval E11-13HR012439
The above approval mark affixed to a vehicle shows that the vehicle type concerned has, with regard to braking, been
approved in the United Kingdom (E 11) pursuant to UN Regulation No 13-H under approval number 012439. The first
two digits of the approval number indicate that the approval was granted in accordance with the requirements of the
01 series of amendments to UN Regulation No 13-H.
