Final answer:
Railroad crossing buck signs are crucial for driver safety as they indicate the presence of tracks and the number to be crossed. Drivers should use caution and count the tracks before crossing to ensure safe passage and awareness of potential multiple trains.
Step-by-step explanation:
Railroad crossing buck signs are vital for safety and are designed to alert drivers to the presence of a railroad crossing and the number of tracks to expect. Ignoring these signs is hazardous. Instead, drivers should always use caution and be prepared to count the tracks before proceeding when approaching a railroad grade crossing. This ensures that drivers are aware of how many sets of tracks they need to cross and can be especially cautious if there are multiple tracks, which may mean additional trains could be approaching from either direction or shortly after the first train passes.
Railroad crossing buck signs are posted at every railroad, highway, road, or street grade crossing. These signs serve to indicate the location and the number of tracks crossed. Therefore, option C) 'Use caution and count the tracks before crossing' is the correct choice. It is important to be aware of the number of tracks when crossing a railroad to ensure safety.
