DENVER - The Colorado Department of Transportation (CDOT) will give large trucks the option of using an alternate traction control device known as the AutoSock(tm) next winter.

AutoSock is a fabric that slips over a vehicle's outer driving wheels, providing extra traction on snowy and icy roads. It also can be installed over the tire in much less time than traditional chains. CDOT engineers, the Colorado State Patrol (CSP) and trucking experts analyzed the AutoSock and, based on initial test data, recommended a "probationary approval" to verify the device actually performs well in winter driving conditions. The evaluation will be conducted during the 2008-2009 winter season for commercial vehicles (both single and double axle) exceeding 26,000 GVW.

"Both CDOT and CSP will be closely monitoring AutoSock's performance during winter storms and chain law conditions," says CDOT Chief Engineer Pam Hutton. "Our hope is that it performs effectively and it becomes another tool to help us keep traffic moving during winter driving conditions."

If AutoSock performs successfully after next winter and receives a positive evaluation from CDOT and CSP, it may result in a recommendation for permanent approval as an alternative traction device. However, if it does not perform up to the initial data provided and traffic problems occur, probationary approval will be immediately withdrawn.

The AutoSock currently is used extensively as an alternate to tire chains in Europe.
