The average time it takes for a typical tractor-trailer unit to clear a double track is indeed more than 15 seconds. This duration is significant because of the length and size of the tractor-trailer, which affects its ability to maneuver. It has to ensure that it moves through the crossing safely to avoid any potential collisions with trains, which can be particularly dangerous.

Tractor-trailers require a longer length of time to clear double tracks due to their size and the potential need to accelerate slowly to gain enough speed, especially when fully loaded. Understanding this timing is critical for drivers to maintain safe operations when approaching railroad crossings.

In practice, drivers are trained to be cautious and vigilant as they approach these crossings, recognizing that their vehicle's dimensions necessitate a longer time to clear the tracks compared to lighter vehicles. Thus, recognizing that it can take more than 15 seconds for such units to clear is essential for ensuring safety around railroad areas.
