Now, if you make this mistake at the toll plaza, a double fine will be deducted online..

FASTag Wrong Lane Penalty Rules: An electronic toll collection system has been implemented across national highways nationwide to make travel smoother and faster. However, due to haste or negligence, many drivers steer their vehicles into the wrong lanes. According to the National Highways Authority of India's (NHAI) operational guidelines, if a passenger car driver enters a FASTag lane designated for commercial vehicles, oversized transport, or special-purpose vehicles, they will be charged double the standard toll rate.

**Risk of Challans and Legal Action**
The NHAI has taken strict measures to prevent traffic disruptions and congestion on national highways. Modern high-definition sensors and cameras at toll plazas automatically identify a vehicle's size and category; if a vehicle enters the wrong lane, the system immediately issues an alert. Subsequently, traffic police stationed near the toll booths can issue on-the-spot fines or e-challans for lane indiscipline and dangerous driving under the Motor Vehicles Act.

**Mistakes That Lead to Double Penalties**
Driving a passenger car into a lane reserved for trucks and heavy commercial vehicles. If there is insufficient balance in the FASTag wallet, the automatic sensor fails to scan the tag and the barrier does not open, causing the vehicle to be categorized incorrectly. Double toll charges may also apply if the FASTag is not affixed correctly to the front windshield or is merely held in hand instead of being mounted as required. The tag gets blocked if KYC is incomplete or not correctly linked to the vehicle number.

**How ​​to Avoid Penalties and Inconvenience**
Pay close attention to overhead electronic indicators and signboards 100–200 meters before reaching the toll plaza and drive only in the lane designated for your vehicle category. Ensure there are sufficient funds in the bank app or wallet linked to your FASTag before hitting the highway. Affix your FASTag sticker on the inside of the car's front windshield, right in the center.
