When is shifting gears in a passenger transport vehicle not permitted?

Shifting gears in a passenger transport vehicle is not permitted when crossing railroad tracks due to the need for maximum control and stability at a critical point in roadway interaction with trains. When approaching and crossing railroad tracks, the vehicle should be in low gear to ensure that it can cross safely without stalling or losing power. This is particularly important because the consequences of a vehicle becoming immobilized on the tracks can be severe.

Maintaining a steady speed and gear ratio can help ensure that the vehicle can cross the tracks efficiently and safely. Therefore, avoiding any gear changes at this critical moment minimizes the risk of stalling and helps the driver maintain full control of the vehicle as they navigate the crossing. This strategic approach helps to protect passengers and avoid potentially dangerous situations with oncoming trains.
