Georgia Department of Transportation spokeswoman Jill Goldberg says the agency is awaiting results of a study in Texas, where several interchanges have been equipped with radar to detect wrong-way drivers and alert authorities. Similar technology has been deployed in the Milwaukee area.
The National Transportation Safety Board said in a December report that states have identified effective measures to counter wrong-way driving, but there's limited federal guidance on using proven strategies to prevent it.
The NTSB found that, on average, 360 lives are lost each year in wrong-way collisions and about 60 percent of the crashes involve alcohol.
I suspect there are some instances where a sober driver managed to find himself going the wrong way. But, I also suspect that he would quickly realize his mistake and make the necessary correction. While an alcohol impaired driver might not be able to work this all out.
