New study raises concerns about big rigs on the roads

CHARLOTTE, NC (WBTV) -

When you leave your home and drive along the interstate, you will most likely see dozens of tractor trailers alongside of you.

A new study finds under-ride guards on the back of trucks do a great job of keeping vehicles from going underneath them.

However, experts find problems arise when a vehicle hits a truck from the side.

The Insurance Institute for Highway Safety finds many companies use under-ride guards that are stronger than the law requires. The agency says the number of tractor trailer-related has dropped in the past ten years because of them.
