Wrong-Way Crashes: Could A $300 Sign Stop Killer Wrecks?

Nearly 4,000 people have been killed in wrong-way traffic crashes nationwide over the last decade, but the state with the worst record has not made some simple safety changes that some experts say could save lives, an NBC News investigation has found. Data from the Texas Department of Transportation, obtained by NBC-DFW, shows wrong-way accidents there jumped 13 percent in the last year, even as other states have managed to reduce the number of those collisions with an easy fix: lowering warning signs on highway ramps. Head-on wrecks are particularly deadly: more than one in five result in a fatality.
