How long does it generally take a typical tractor-trailer to clear a double railroad track?

A typical tractor-trailer can take more than 15 seconds to clear a double railroad track due to several factors. The length of a tractor-trailer can vary, but they often reach lengths of 70 to 80 feet or more, particularly when considering the trailer portion. As a result, they require a longer time to completely cross the width of the tracks, especially when accounting for the additional time it takes for the vehicle to accelerate to a safe speed after stopping at a railroad crossing.

Furthermore, safe driving practices dictate that drivers should always approach railroad crossings at a cautious speed, allowing for adequate stopping distance if needed. This careful approach, combined with the physical dimensions of the vehicle, contributes to the fact that clearing the tracks will typically take longer than 15 seconds.

Understanding the dynamics of large vehicles in relation to railroad crossings is crucial for safety, especially to avoid any collisions with trains or dangerous situations for both the driver and other road users.
