Roadway workers may cross tracks without track protection as long as they do what?

The correct answer emphasizes the importance of safety and situational awareness when roadway workers approach or cross tracks. Stopping and looking in both directions allows workers to visually assess the environment for any oncoming trains or other hazards. This action is critical because it helps prevent accidents and ensures that workers are aware of their surroundings before moving across the tracks.

While there are various procedures and requirements that contribute to worker safety, none are as fundamental as the act of stopping and maintaining visual vigilance. This simple yet effective practice is a key component of safety protocols in railway operations, as it directly addresses the immediate risks associated with track crossings.

The other options present actions or requirements that might be relevant in specific contexts but do not substitute for the basic necessity of situational awareness when crossing tracks.
