POLICE will be using unmarked cars to target drivers speeding on East Yorkshire's roads.
Humberside Police are launching a month-long campaign to crackdown on drivers breaking the speed limit.
Officers say "excessive and inappropriate speed" is one of the most common cause of fatal and serious crashes.
Traffic officers in the East Riding will be concentrating on the A165 between Brandesburton and Bridlington and the A614 between Goole and South Yorkshire.
PC Simon Carlisle, casualty reduction officer for the East Riding, said: "These are the two routes where we have identified speeding and inappropriate overtaking as a key factor in collisions.
"We will be using both marked and unmarked vehicles on these routes to enforce the speed limit."
Dedicated officers will be working shifts dedicated to enforcing the speed limit in the East Riding and Hull. PC Keith Ward, casualty reduction officer for the city, said they will be focusing on five roads where speeding is a problem.
Safer Roads Humber has provided extra funding to pay for more officers to be out on the streets with speed guns.
PC Ward said: "These officers won't be doing anything but enforcing the speed limit. They won't be going to crashes or doing any other jobs, they will be dedicated speeding patrols.
"We are looking at the sites where we know speed has been an issue and a factor in collisions. I have identified five sites, which we will not be telling drivers about in advance.
"Most drivers will admit to regularly travelling a few miles over the speed limit, but even that increases the risk you will seriously injure or kill someone."
Drivers who are caught could be given a £60 fine and three penalty points, offered the chance to go on a speed awareness course, or summonsed to court.
Both officers hope the campaign will encourage drivers to stick to the limit.
PC Carlisle said: "We do have an issue with overtaking and speeding on those roads, so I would urge drivers not to get frustrated if they find themselves behind a slow- moving vehicle.
"If they are involved in a collision, it will not only ruin their day and possibly their life, but also someone else's."
