When crossing railway tracks, it is crucial to maintain control of your vehicle and ensure your focus is on the tracks and the surrounding area. The correct choice involves not changing gear while crossing these tracks, as doing so could disrupt the stability and control of the vehicle at a critical moment. If you change gears, you might inadvertently cause the vehicle to lurch or stall, putting you in a dangerous situation on the tracks.

Maintaining a steady speed and avoiding abrupt actions ensures that your vehicle remains stable during the crossing. By not changing gears, you help prevent additional complications that could arise from an unexpected loss of power or control. The focus should be on crossing safely and smoothly, which is best achieved with a consistent approach.
