South Mimms

The country’s network of motorways and major A roads – the Strategic Road Network operated and maintained by Highways England – is one of the safest road networks in the world yet there are still thousands of avoidable incidents each year. South Mimms is home to the Highways England Regional Control Centre just off the M1. We’ll look at the rules for driving on motorways and the incidents that have to be dealt with.

Safer driving on motorways

Whatever part of England’s motorway network you’re using, we want you to stay safe, follow the signs and keep us all moving.

England’s motorways connect people to families and friends, workers to jobs and businesses to their customers, which helps our nation thrive.

We want all drivers to have a safer, smoother journey. How you can help:
