Three new mobile speed camera sites have started operating in West Lothian to ensure drivers stick to the speed limit.
Armadale, Livingston and Longridge will have either the mobile safety camera van or motorbike units visiting on a regular basis.
The new zones are in residential areas with a speed limit is 30 mph.
Sites only become eligible for a speed camera if there has been a history of crashes and speeding.
It is unacceptable that people still continue to drive well above the speed limit
Safety Camera Partnership
In Armadale, from 2002 to 2004, there had been two crashes resulting in people being killed or seriously injured and seven crashes with people receiving injuries.
Colin McNeil, Lothian and Borders safety camera partnership manager, said: "It is unacceptable that people still continue to drive well above the speed limit.
"In a residential area where there are so many potential hazards 30 mph really is the maximum.
"At 35 mph a driver is twice as likely to kill a pedestrian as they are at 30 mph.
"It is the aim of the partnership to reduce crashes so I hope that the presence of the mobile camera at the three new sites will act as deterrent and slow drivers down."
West Lothian Council joined Lothian and Borders Safety Camera Partnership in July 2004 and now has a total of 10 mobile safety camera sites.
The three new sites are at the A89 West Main Street in Armadale, the B7015 Howden South Road in Livingston and the A706 Longridge Village.
