NOTICE: Although President Trump signed an Executive Order regarding diesel last night, off-road CANNOT be used as on-road at this time in WI! Each state must authorize the use of off-road in on-road vehicles. This would be done through the Governorβs Office. Conversations with a Commercial Vehicle Inspector commented, βThrough my contacts with WI Revenue Service and WI State Patrol, running off-road is NOT acceptable until the State agrees to these terms in WI!.β
Semi-truck diesel tanks will continue to be dipped until WI authorizes.
