How long does it take a typical tractor trailer to clear a single track?

A typical tractor-trailer takes about 14 seconds to clear a single track. This time frame can vary based on several factors, including the speed of the vehicle and the specific design of the track or grade crossing. The estimate of 14 seconds considers the average length of a tractor-trailer, which often exceeds 50 feet, and is designed to provide a safety margin in terms of visibility and reaction time for both the driver and any train operators.

While a shorter duration might seem plausible, it doesn’t account for the substantial size and weight of these vehicles, which require more time to safely navigate across railway tracks. Additionally, slower speeds when approaching crossings can further extend the time needed to clear the track. Thus, the selection of 14 seconds aligns with standard safety practices for both commercial driving and rail operations.
