What action should you take when a railway employee signals you to stop at a crossing?

When a railway employee signals you to stop at a crossing, stopping immediately is the correct action to take. Railway employees are trained to manage railway crossings and ensure the safety of both pedestrians and motorists when trains are present or approaching. Their signals are based on real-time conditions and the presence of trains, which may not be visible to drivers.

By stopping immediately, you are prioritizing safety and complying with the directive given by the railway employee. This action helps prevent potential accidents and ensures that you remain alert and attentive to any further instructions or the possibility of a train approaching.

The other options suggest actions that could jeopardize safety and disregard the authority of the railway employee's signal, which is critical for ensuring the safe passage at crossings.
