What must you not do when crossing railway tracks?

When crossing railway tracks, it is crucial to maintain control of the vehicle to ensure safety. Changing gears is particularly risky because it can divert the driver's focus and potentially lead to hesitation or an unexpected stall at a critical moment. Shifting gears may also cause the vehicle to lose momentum, making it more difficult to cross the tracks safely and quickly.

Maintaining a consistent speed allows for better decision-making and reduces the risk of being caught on the tracks, especially if a train is approaching. Therefore, avoiding gear changes while crossing railway tracks is essential to ensure that the driver can navigate the crossing without unnecessary complications.
