Motorists traveling in Rush Township may soon see signs alerting them of their speed.

On Monday, township supervisors approved the purchase of three “speed alert” mobile trailers from All Traffic Solutions for $32,181.

The trailers contain signs that digitally display drivers’ speeds as they’re clocked by radar. The sign flashes the speed until the motorist slows to or below the posted speed limit.

They will be placed on Routes 309 and 54, along with Ben Titus Road.

“We will move them around every few weeks according to PennDOT rules,” Supervisor Robert Leibensperger said.

The signs, he said, are a way to reduce motorists’ speed and possibly save lives or serious injuries caused by speed-related crashes.

Leibensperger said a recent serious accident occurred on Route 309 near Ben Titus Road, a spot where other crashes have occurred.

There have been fatalities near the site, he said.

Board Chairman Shawn Gilbert noted that the speed alert trailers may also aid police.

“Rush Township cannot afford a full-time police department,” he said. “We can afford a chief and part timers.”

The signs, he believes, will help slow down drivers when officers aren’t on duty.

“We have to do something,” Leibensperger added.

Supervisor George Gerhard said that there is a problem with speeding in the township.

But he said he wasn’t sure if police would agree that the speed trailers could help solve the problem.

“I don’t believe that three of these in Rush Township is warranted,” said Gerhard, who voted against the purchase.

Gerhard also asked whether PennDOT had approved the speed trailers’ use in the township.

Leibensperger said he would contact PennDOT — after the purchase — to get approval for their locations and movement.

Gilbert said that if the signs save just one life, the purchase “is worth it.”

The sign that will be placed on Ben Titus Road will be moved in the winter, likely to Route 309, since the road is not wide enough to support the sign while snow plowing is underway.

Neighboring Ryan Township recently purchased similar sign trailers, which it employs on Route 54 and other state roads in the township.
