CTC-VIS Problems Can Delay Compliance

The Clean Truck Check system can create confusion when vehicle information is missing, test records are unclear, account access is difficult, or a vehicle does not appear as expected. For fleets, owner-operators, and diesel RV owners, CTC-VIS issues can quickly become stressful when a registration deadline is approaching.
