What must you do if a flag person signals you at or near a railroad crossing?

When a flag person signals you at or near a railroad crossing, it is crucial to follow the flag person's signals. This is because flag persons are specifically trained to ensure the safety of drivers and pedestrians in areas where there may be risks associated with rail traffic. Their signals provide real-time guidance, particularly in circumstances that may not be visible to drivers, such as an approaching train that could be at high speed.

Ignoring the flag person's signals or relying solely on the traffic lights, if present, can lead to dangerous situations, including potential collisions with trains. Therefore, adhering to the instructions provided by the flag person ensures all individuals involved are kept safe and that you are complying with the rules designed to protect you at high-risk locations like railroad crossings.
