I just can't drive . . . 85

The Lone Star state is poised to unveil a 41-mile stretch of toll road where the speed limit will be a whopping 85 mph. The road runs just east of the crowded I-35 San Antonio-Austin corridor.

While the higher limit might be enticing to some, research indicates that with higher speed comes more accidents.

A 2009 report in the American Journal of Public Health studied traffic fatalities in the U.S. from 1995 to 2005 and found that more than 12,500 deaths were attributable to increases in speed limits on all kinds of roads.

The Texas Legislature last year approved 85 mph limits for some new stretches of road. The strip of toll road running from Austin to Seguin, about 35 miles northeast of San Antonio, will be the first to allow that speed when it opens in November.
