A local lawmaker is taking a closer look at a company that keeps highway construction workers safe.

Congressman Charlie Dent visited Royal Truck and Equipment in Coopersburg.

The company makes trucks and Truck Mounted Attenuators -- or TMAs.

These devices are able to absorb impacts from wayward vehicles keeping construction workers out of harm's way.

"This company really does play a vital role in making sure our construction sites are safe," said U.S. Representative Charlie Dent (R- PA). "And there's a lot of road construction going on. This company is absolutely essential."

Dent also wants to see how Royal Truck fits in on Capitol Hill.

Congress is working on a "Service Transportation Bill."

The bill is expected to generate money for highway road improvements and safety.
