What action is required if a driver is uncertain about safety at a railroad crossing?

When a driver is uncertain about safety at a railroad crossing, the appropriate action is to stop and check. This approach emphasizes the importance of ensuring one's own safety and the safety of others. At a railroad crossing, trains can approach rapidly and may not always be visible until they are very close. Stopping allows the driver to carefully assess the situation, looking for any oncoming trains and heeding warning signals.

By taking this cautious step, a driver can avoid potentially dangerous situations that might arise from proceeding without adequate knowledge of the crossing conditions. This action underlines the critical nature of vigilance and caution when it comes to railway safety, especially since trains often travel faster and are less forgiving than road traffic.
