SALEM – Does your trucking company use preclearance devices to bypass roadside weigh stations? These services provide an efficient solution to the industry for weighing trucks in motion, saving time, fuel and money. However, when left unmonitored, they may lead to a roadside citation and unnecessary audit of your reported taxes.

Truck bypassing weigh station

Educate your drivers and office support staff that preclearance devices are registered to a specific power unit and should never be moved from unit to unit without being properly updated. If a driver fails to update their device or log out as they move it from Truck A to Truck B, it will result in false “hits” or bypass readings of Truck A when the device is in Truck B. These false readings will appear as evidence of non-reported miles in Oregon. If your company is unable to justify the incorrect readings, you may be liable for unpaid tax for Truck A.

Our recommendation: Always update all preclearance devices with Oregon when moving them from one unit to another.
