How long does it typically take for a tractor-trailer unit to clear a double track?

It typically takes a tractor-trailer unit at least 14 seconds to clear a double track. This time frame is critical for ensuring safety when crossing railway tracks, particularly those with multiple lines. The reason this duration is established is due to the length and speed of the tractor-trailer, as well as the need for a safe clearance to avoid potential collisions with trains.

When approaching double tracks, it's essential for drivers to be aware of the time it takes not just for their vehicle to cross, but also to ensure that no obstruction is caused while waiting for trains. Understanding this timing helps enhance safety practices for both truck drivers and train operators, emphasizing the importance of caution at railway crossings. Recognizing the specific time needed to clear the double tracks allows for better planning and decision-making while driving in proximity to railroads.
