SALT LAKE CITY -- Last December, Utah Department of Transportation crews changed the roadside speed limit signs from 65 mph to 70 mph along most Wasatch Front interstates. But UDOT spokesman John Gleason said the speed limit increase hasn't had much of an effect.
"It really hasn't affected the speeds in which people are driving. They were driving 70 and above before and they are still," Gleason said.
Drivers tend to travel at the speeds they feel are safe, Gleason said, and the speed limit was adjusted to reflect that level.
UDOT also considers the geography and the information gathered at crash sites when making decisions about speed limit adjustments.
