Road safety: UK set to adopt vehicle speed limiters

Speed limiting technology looks set to become mandatory for all vehicles sold in Europe from 2022, after new rules were provisionally agreed by the EU.

The Department for Transport said the system would also apply in the UK, despite Brexit.

Campaigners welcomed the move, saying it would save thousands of lives.

Road safety charity Brake called it a “landmark day”, but the AA said “a little speed” helped with overtaking or joining motorways.

Safety measures approved by the European Commission included intelligent speed assistance (ISA), advanced emergency braking and lane-keeping technology.

The EU says the plan could help avoid 140,000 serious injuries by 2038 and aims ultimately to cut road deaths to zero by 2050.

EU Commissioner Elzbieta Bienkowska said: “Every year, 25,000 people lose their lives on our roads. The vast majority of these accidents are caused by human error.

“With the new advanced safety features that will become mandatory, we can have the same kind of impact as when safety belts were first introduced.”

What is speed limiting technology and how does it work?

Under the ISA system, cars receive information via GPS and a digital map, telling the vehicle what the speed limit is.

This can be combined with a video camera capable of recognising road signs.

The system can be overridden temporarily. If a car is overtaking a lorry on a motorway and enters a lower speed-limit area, the driver can push down hard on the accelerator to complete the manoeuvre.

A full on/off switch for the system is also envisaged, but this would lapse every time the vehicle is restarted.

How soon will it become available?

It’s already coming into use. Ford, Mercedes-Benz, Peugeot-Citroen, Renault and Volvo already have models available with some of the ISA technology fitted.

However, there is concern over whether current technology is sufficiently advanced for the system to work effectively.

In particular, many cars already have a forward-facing camera, but there is a question mark over whether the sign-recognition technology is up to scratch.

Other approved safety features for European cars, vans, trucks and buses include technology which provides a warning of driver drowsiness and distraction, such as when using a smartphone while driving, and a data recorder in case of an accident.
