SAM2 Speed Signs
What is a SAM2?
It is a vehicle activated sign that displays the speed of an approaching vehicle. If the vehicle exceeds the speed limit a ‘SLOW DOWN’ message is shown, once the limit is exceeded by 10mph the speed is no longer shown and the ‘Slow DOWN’ message remains, this removes the temptation for some drivers to see what speed they can register!​
Who owns the SAM2 Signs?
The Parish Council purchased one SAM2 sign and the Community Speed Watch group manages this on behalf of the parish. ​
Where can SAM2 be placed?
The sign is deployed in the 30mph limit, on stretches of road that are of concern. We will not place the sign where it will cause an obstruction or be an inappropriate distraction. The current specific sites have been agreed between the Parish Council and an officer of Norfolk County Council’s Highways department.​
​How can the data be used?
Although the police have 'no capacity' to look at the data and the Safety Camera Partnership only responds to the data from their own cameras, parish and/or town councils based on their own reading of their data, can flag up patterns and concerns, to see if police action could be taken. The sign also encourages drivers to be more mindful of the speed limit and reduce their speed when travelling through the village.
