A "Vehicle Class Mismatch" occurs when the vehicle details linked to your FASTag do not match the actual class of your vehicle. Each vehicle is assigned a specific class based on its type (e.g., car, truck, or bus), and toll charges are calculated accordingly.
When there is a mismatch, the toll system cannot verify your vehicle's class, leading to payment failures. This issue can arise due to incorrect registration details, applying a FASTag meant for one vehicle on another, or errors during the registration process.
Such mismatches can block your FASTag, cause delays at toll plazas, and result in additional charges if you need to pay in cash. Resolving this issue promptly ensures a hassle-free travel experience.
