Get involved and support us to reduce speed limits to 20mph


Communities can support us by spreading information and messages through communication channels. Community support has proven integral to the successful implementation of 20mph sites elsewhere.

A good community support network will change behaviours and attitudes towards traffic speeds. This will increase the likelihood limits become self-enforcing.

While waiting for 20mph to be applied where you live, there are many ways that communities can help:

  • Community Speedwatch - this site tells you more about the scheme and how to get involved.
  • Operation Snap - you can provide photo or video evidence of driving incidents on this website.

Supporting traffic calming

We will not be applying traditional traffic calming. Delivery includes legal signage and low-cost gateway features, where required. Transition into a community needs to be clear to drivers.

Gateway features may include:

  • Enhanced signage
  • Road roundels (painted markings on road)

Targeted support will be provided to non-compliant sites with increased activity through our communications and engagement strategy.  As well as mobile speed activated signs and/or lining works.

We need communities to work with us through initiatives such as:

  • Community Speedwatch
  • Operation Snap
  • Deployment of mobile speed signs

Other committed 20mph schemes

There are other 20mph schemes advancing. The majority of these are through the Community Highway Scheme programme. We recognise communities want to see 20mph delivered as early as possible, but this change will not happen overnight. Delivery will take many years.

20mph speed limits can still be nominated through the Community Highway Schemes for early delivery. These will be designed with assessment criteria developed to ensure consistency across Cornwall.

20mph speed limit schemes progressed early via this route will not benefit from the coordinated programme of communications and engagement support that would otherwise be provided alongside the rollout.

Measures to support the 20mph rollout can also be nominated through this process.
