JACKSON, Wyo. (AP) — Authorities are stepping up traffic enforcement along a stretch of roadway in western Wyoming in response to semitrailers ignoring the seasonal closure of Teton Pass.

Lt. Matt Brackin says Wyoming Highway Patrol has been using new technology for about a year that alerts troopers to the semitrailers.

Teton Pass is closed to all tractor-trailer traffic from Nov. 15 to April 1 every year.

Brackin says many truck drivers have been ignoring the visible warnings, resulting in crashes or fines.

He says the patrol is bringing in additional troopers to monitor the roadway, as the agency is about six troopers short in the area.

Teton Pass runs between Wilson, Wyoming, and Victor, Idaho.
