Final answer:
True, drivers should look, listen, and slow down at railroad crossings without warning signals for safety and to prevent accidents.
Step-by-step explanation:
When approaching a railroad crossing that has no warning signals such as electric flashing lights or gates, a driver should indeed look, listen, and slow down. This practice is true and highly important for safety. Many vehicles speed through the intersection without regard to the posted speed limit, and the absence of warning signals increases the risk of an accident. Furthermore, pedestrian safety could be compromised, highlighting the need for vigilant driving behaviors. Traffic signals serve to regulate the flow of traffic and enhance safety by ensuring vehicles slow down and pedestrians can cross at appropriate times. Without such signals at railroad crossings, drivers must be even more cautious to avoid dangerous situations that could lead to accidents, or in the worst-case scenario, loss of life.
