When is it unnecessary to stop at railroad crossings?

When traffic control signals indicate to proceed, it is unnecessary to stop at railroad crossings because these signals provide specific instructions regarding the flow of traffic. Traffic control signals are designed to communicate with drivers, and if they indicate that it is safe to move forward, this implies that there are no imminent dangers at the crossing, such as an approaching train.

Understanding this concept is important for safety, as it allows for the smooth movement of vehicles while still adhering to required safety protocols at railway crossings. In contrast, other scenarios such as flashing lights, the presence of a train, or specific signals indicating the need to stop would necessitate caution and a full stop to ensure the safety of all road users, particularly in preventing accidents at these potentially hazardous locations.
