Avon and Somerset Police publish a weekly schedule of locations where it will be carrying out speed enforcement.
The force uses two types of mobile speed cameras which are approved by the Home Office.
Both types are operated by trained staff and use laser light pulses to measure the changing distance between the speed gun and the vehilce being checked.
The force says the system can then accurately calculate the vehicle’s speed.
The force warns that "enforcement may take place at any location within the Avon and Somerset Constabulary area."
Here is the schedule of locations for Somerset West and Taunton in the week starting Monday, January 2.
