Speed Reduction

Grimston Parish Council with a grant from Norfolk County Council purchased a  mobile Speed Activated Sign (SAM2) in 2020 with the aim of reminding drivers to keep within the speed limit in those areas where residents have reported issues with speeding vehicles.   The unit also records the volume of vehicles and the speeds at which they are travelling.  A SAM2 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.

Pedestrians stand a much better chance of survival if your speed is lower.
If you hit a pedestrian:

      • at 40 mph there is a 90 percent chance they will be killed.
      • at 35 mph there is a 50 percent chance they will be killed.
      • at 30 mph there is a 20 percent chance they will be killed.
      • at 20 mph there is a 2.5 percent chance they will be killed.

The SAM2 is deployed at sites that have been approved by Norfolk County Council.  The unit can be at one site for up to 4 weeks but must not return to that site within 8 weeks. The movement of the sign ensures that regular drivers do not become over-familiar with the warning.  The Parish Council has a small team of volunteers who safely move the sign from each location.
