CHEYENNE, Wyo. (AP) — The Wyoming Highway Patrol is launching an effort to crack down on impaired motorcycle drivers.

Wyoming usually sees an increase in motorcycle use during this time of year. As the number of motorcycles increases on highways, so does the number of reported motorcycle crashes.

In 2011, out of the 308 reported motorcycle crashes in Wyoming, 24 of those crashes involved impaired motorcycle drivers. So far this year, Wyoming law enforcement officers have investigated six motorcycle fatality crashes. Two of those involved alcohol.

The Patrol says extra troopers will be assigned to northeast Wyoming during the 72nd Sturgis Motorcycle Rally, which begins Aug. 6 in South Dakota.
