A Community Speed Watch scheme allow volunteers to monitor the speed of passing vehicles using a speed detection device.
The volunteers record the details of vehicles which are exceeding the speed limit. These details are passed to the Police, who will issue a letter to the vehicle owner, advising them of the dangers of speeding, and reminding them of the law. If three letters are issued to the same vehicle owner, the Police carry out further investigation.
As Community Speed Watch volunteers are highly visible and make use of a speed detection device, it is usually clear to vehicle drivers their speed is being monitored. This may be enough for many motorists to slow down. Some motorists may mistake the volunteers for police officers.
The ‘community’ element of Community Speed Watch could have a more positive effect on some vehicle driver’s attitudes compared to engineering schemes.
Community Speed Watch may only reduce vehicle speeds when the volunteers are present at the road side. However, there should be a significant effect on vehicle drivers who receive letters as a result of exceeding the speed limit. Other drivers may continue to reduce their speeds at all times, as they might expect Speed Watch to return to the same place, or appear in another area.

Mobile Vehicle-activated signs (MVAS) are an electronic sign which only become visible when approaching motor vehicles are exceeding a certain speed. The signs normally display the speed limit, however they can also display the actual speed on the sign and these are called Speed Indicating Devices (SID).
MVAS are formed of many bright lights which only turn on when the target motor vehicle is in plain view of the sign.
MVAS have a short-lived effectiveness in reducing speeds. Unfortunately drivers become too familiar with them when they are situated in one particular location for long periods of time. Can be most effective when positioned near downhill gradients reminding drivers who may be inadvertently speeding.
When MVAS are relocated regularly around different parts of the village or town this can increase effectiveness as drivers will be unaware of where the sign will be next time they travel.
| || |
- Parish/Town Council’s would be required to maintain and relocate the signs going forward in accordance with Cambridgeshire’s Highway Asset Management Policy.
- Location of the MVAS needs careful consideration as light pollution can cause concerns with residents
- MVAS must be placed on a straight stretch of road to allow the radar device to accurately judge the speed of approaching motor vehicles
|Equipment||£3,000 - £4,500|
|Works||£1,000 - £2,500|
|Total||£4,000 - £7,000|
|Costs above are to supply the MVAS, associated mounted equipment, spare batteries and supply and install a number of posts for the device to be moved around.|
We recognise that MVAS can be a popular speed educational tool. Should you wish to apply for permission to use them on the highway please complete this application form and return by post to the address specified or by email to [email protected].
You will be required to agree to a Memorandum of Understanding to ensure the MVASs correct use on the highway.
There are three national speed limits; 30mph on roads with street lighting, national speed limit of 60mph on single carriageway roads and national speed limit of 70mph on dual carriageways and motorways. These national limits are not appropriate for all roads.
The speed limit regime enables traffic authorities, like Cambridgeshire, to set local speed limits in situations where local needs and conditions suggest a speed limit which is different from the standard national speed limit. Buffer zones are becoming ever popular around Cambridgeshire and generally offer a short section of 40mph approaching a village or town’s 30mph limit. This can help to ensure that a driver is travelling more slowly on the approach to the lower limit.
Changing the speed limit and introducing nothing but a change in sign is very unlikely to ensure driver compliance on its own. If all speed limit signage were taken away, the driver should instinctively know what the speed limit is from the environment: a driver will choose different speeds for a rural road through open countryside and a built up road through a town centre.
Alternatively, the road environment should be such that higher speeds are difficult to achieve because of the nature of the road, e.g. traffic calming is present.

Gateways are designed to highlight the entrance to a Parish, Town or Village and/or change of speed limit. In Cambridgeshire the most common method is through installing gates and village name plates at the entrances to villages, often in combination with the speed limit terminal sign.
Drivers tend to notice and accept the distinction between the two speed limits when there is a more obvious presence on the entrance.
The speed reducing effect is highest when gateways are first installed. Many drivers subconsciously adjust their speed according to the surroundings, driving more slowly in built up areas and faster in rural areas with open fields. A gateway feature signals that a driver is leaving a higher speed area and entering residential area. However, the benefit can reduce over time as drivers become used to them.
These gates are made from a blend of wood fibre, recycled thermoplastics and adhesive resins. They give the appearance of wood with all the longevity of plastic so they will not rot or require varnishing or painting.

- These gate features will become the Parish/Town Council’s asset and Cambridgeshire County Council will not maintain or replace them.
- Sizes of gates will be restricted by the width available in the verge.
