1. 12 seconds

2. 14 seconds

3. 16 seconds

4. 18 seconds

The correct answer is: 14 seconds

The average time it takes for a tractor-trailer to clear a single railroad track is approximately 14 seconds. This time frame is significant for several reasons, primarily related to safety and coordination when dealing with railroad crossings. Understanding the time it takes to clear the track is essential for drivers, particularly those operating large vehicles like tractor-trailers. These vehicles require more time and distance compared to smaller vehicles due to their size and weight. When approaching a railroad crossing, it’s critical for drivers to be aware of this time requirement. This awareness ensures that they do not become stranded on the tracks during an approaching train's transit, which can lead to catastrophic accidents. By knowing that it typically takes around 14 seconds, operators can make informed decisions about how to approach crossings, ensuring they maintain a safe distance and not initiate a crossing unless they can clear the tracks in time. This understanding promotes both personal safety and the safety of all road users.
