20mph speed limits and zones for residential areas

Tackling speeding vehicles in residential areas

Speeding vehicles in residential estates is a safety concern and so MK Council have some measures to help.

There are two types of method we can use in residential areas which are: speed reduction such as a 20mph speed limit or zone, and traffic calming such as speed humps. 

If you and other local residents believe there is a problem with speeding vehicles in your local area there are some things we can do to help.


Regulations for introducing 20mph restrictions.

There are two approaches that may be used when implementing restrictions either through a 20mph limit or a 20mph zone

  • 20mph speed limits can be introduced through a Traffic Regulation Order (TRO) and supported by signing only. These are used where vehicle speeds are already relatively low and therefore compliance is easy to achieve.
  • 20mph speed limit zones can also be introduced through a TRO but are supported by both signing and physical speed control measures. This approach is used where vehicle speeds are higher and helps to achieve compliance.

In new estates, roads can be designed to naturally support a 20mph speed restriction. 

Before you make an application, read through the guidance notes. There are two petition templates for you to use if you wish, one for each type of 20mph application. Applications for new 20mph restrictions which are supported by a majority of local residents will be positively considered.

Applications must be received by 31 August for consideration each year.


After your application is received

On receipt of an application the following options will be looked at: 

20mph speed limit with terminal and repeater signing only

Where mean speeds are already below 24mph the introduction of a 20mph speed limit using terminal and repeater signing only.

20mph speed limit with signing and speed control measures

To help achieve compliance, where mean speeds are 25mph or above, it could be necessary to include additional speed control measures in addition to the terminal and repeater signing.

20mph speed limit zone with signing and speed control measures

To ensure drivers stick to the limit, additional speed control measures may be included in addition to the terminal and repeater signing. This means that no point within the zone is more than 50m from speed control measures.

Do Minimum

Some recently constructed estates already have mean vehicle speeds that lie within 20mph and we could consider a signing only approach at minimal costs.  

Complex Sites

For older existing estates which have 30mph speed limits and would be complex to alter, we would work with the Police and stakeholders to consider options to help support the introduction of a new 20mph restriction.

How we choose which schemes will go ahead

All applications for 20mph schemes will be looked at to see if there is local support and a need for a speed reduction scheme. This list will be then be prioritised based on our annual budget for these schemes. 

We'll then carry out further consultation with the local communities on the scheme design and to agree how it will be implemented and monitored.

The aim will always be to achieve a scheme that is self-enforcing and/or where maximum encouragement is provided to achieve compliance without the need for enforcement.
