The 20mph speed limits are not advisory. They are legally enforceable speed limits just like 30mph speed limits.


The 20mph speed limits are signed by large 20mph signs as you enter an area with a different speed limit 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.

Speed Management

Speed limits are only one element of speed management and other measures include engineering, visible interventions and landscaping that raise the driver’s awareness of their environment together with education, driver information, training and publicity.

The council and police have been working together to ensure all resources are used effectively in responding to community speeding priorities.

20mph speed awareness course

Avon and Somerset Police enforce speed limits including the 20mph and are one of four constabularies to pilot the 20mph speed awareness course: www.ttc-uk.com/police-referred-courses/speed-awareness-course-20mph/

Community Speed Watch

If driving speeds are too high along your road and in your neighbourhood, and drivers regularly exceed 20mph; work in partnership with the police to address the issue.

Motorists who speed through residential neighbourhoods are very often unaware of the impact their actions have on local residents, or the danger they pose to other road users and pedestrians and this is something we are working with communities to address. Community Speed Watch gives local people the ability to actively get involved in road safety.

  • A Speed Watch consists of local residents, who are willing to volunteer a small amount of time each week to monitor speeds with speed detection equipment.
  • Offenders will receive warning letters, and if they persist in speeding further action is taken by the police
