NBC 5 in Dallas reports that Texas leads the nation in wrong way crashes and is doing little to stop the resulting carnage on our highways.

Despite years of detailed recommendations to prevent wrong-way crashes, an NBC 5 investigation has found the Texas Department of Transportation has yet to implement many of those safety measures on North Texas roads. Meanwhile other states and even local toll road operators have taken steps that appear to be reducing the number of wrong-way incidents.

Texas leads the nation is wrong-way crashes. Using TxDOT data, NBC 5 Investigates has learned there have been almost 3,500 wrong-way crashes in just four years. Most are caused by drunken drivers who blow past warning signs and then slam head-on into other drivers.
