The ‘additional measures’ recommended in the 20mph Review refer to extra signage that will help raise awareness of the 20mph speed limits and increase driver compliance to them. Roads put forward for additional measures will be reviewed to make sure signage is positioned as effectively as possible (subject to suitable locations with existing infrastructure).

The 20mph speed limits are signed by large 20mph signs as you enter an area with a different speed limit (legally required) and you will see smaller repeaters signs saying ‘20’ as you continue to drive through this area. These are sometimes accompanied by 20 roundels painted on the road. As you exit a 20mph speed limit you will see a large speed sign showing the new speed limit you are now entering.


In some locations, a Vehicle Activated signs (VAS) may be recommended. These are electronic signs which only become triggered (visible) when approaching motor vehicles are exceeding a certain speed.
