Final answer:
True. A railroad crossing with no lights flashing does not necessarily mean it is safe to cross without looking first. Always exercise caution at railroad crossings and apply the same principle to traffic safety at intersections without traffic signals. Safety is paramount, and assumptions should never replace cautious observation.
Step-by-step explanation:
The statement "A railroad crossing with no lights flashing does not necessarily mean that it is safe to cross without looking first" is TRUE. Even when railroad crossing lights are not flashing, it is essential to proceed with caution. This approach to safety is relevant not only at railroad crossings but can be expanded to apply to general traffic safety, including intersections and pedestrian crossings.
For instance, at a regular intersection without a traffic signal, vehicles might speed through without adherence to the posted speed limit. Further, pedestrian safety becomes a concern when individuals, such as students, must navigate traffic, potentially risking their safety. In such cases, the installation of a traffic signal is crucial. It serves to regulate vehicle speeds and create safe pedestrian crossing moments. A tragic event, such as an accident with fatal outcomes, could prompt the installation of a traffic signal to prevent future incidents, demonstrating the cause-and-effect relationship in traffic safety management.
In all situations requiring the navigation of traffic, whether by vehicle or on foot, safety should always be the priority, and one should never assume it is safe without proper observation and caution.
