LITTLE ROCK, Ark. (KTHV) – Tractor-trailers and 18-wheelers are common place on Arkansas roads, as the Natural State have a lot of goods to ship out and a lot coming in. But who's in charge of making sure all is well on those trucks?

That would be the Arkansas Highway Patrol. On Tuesday, agents participated in the 30th annual International Roadcheck Safety event.

All eastbound commercial vehicles were directed off Interstate-30 to the inspection station, where the Arkansas Highway Patrol randomly selected vehicles for a "North American Standard Level I Inspection."

So, what are they looking for?

“We're checking pretty much the overall operation of the trucking industry as far as on the road side,” said Jeff Bickerstaff with the highway patrol. “It's been conducted on a national scale at the same time to get an accurate depiction of what's going on with the trucking industry as far as how they're operating.”

The 37-step procedure, called the "most thorough roadside inspection,” includes an examination of both the driver and the vehicle’s mechanical fitness.
