Since the tragic accident that took the lives of their three children, Lori and Chris Coble have become active in the Virginia-based Truck Safety Coalition, a citizen’s lobby working for stricter regulation of the trucking industry, Chris told Today Show anchor Meredith Vieira during a live interview recently.

The Truck Safety Coalition is a partnership between The Citizens for Reliable and Safe Highways (CRASH) Foundation, and Parents Against Tired Truckers (P.A.T.T). You can visit the website at http://trucksafety.org.

According to the coalition, some 5,000 lives are taken in accidents with big rigs.

"This is an industry that’s based on payment on miles driven," Chris Coble told Meredith. "For a lot of truckers, if that truck isn’t rolling, they’re not getting paid, which really sets up an entire industry where it promotes danger and real safety concerns. These truckers are speeding and they’re tired and we’d like to get that changed."

The Cobles are trying to see laws enacted to further limit the hours truckers can be on the road. The man who rear-ended their minivan, Jorge Miguel Romero, 37, had been cited for speeding in 2002 and 2006.

Romero has pleaded not guilty to three counts of vehicular manslaughter and goes to trial on November 29.

The Cobles want the U.S. to adopt the same laws that are in place in Europe and many other countries that require onboard computers in trucks to track their speed and location through a GPS system.

"This has dramatically cut down on truck deaths in other countries," Chris Coble said on the Today Show, adding, "I want to ask lawmakers and everyone else, ‘How come we can’t have that same policy in this country?’ We’re woefully behind."
