JJ Keller Entry Level Driver Training for CDL (Commercial Driver’s License) Practice Test

A sign indicating the number of tracks present at a crossing provides vital information for drivers, allowing them to be aware of potential train activity from multiple directions. This sign is placed on the post below the crossbuck to ensure that it is clearly visible to approaching drivers. Understanding the number of tracks is crucial for safety; if a driver sees a sign indicating multiple tracks, they can be more vigilant, recognizing that trains could come from either direction and that more than one train could potentially be on the tracks at any given time.

While observing the width of the track area might give some indication, it is not a reliable method for determining the number of tracks. Similarly, the sound of an approaching train may not effectively indicate the number of tracks present and can be misleading because the sound can travel over large distances. The presence of a gate at the crossing primarily serves as a warning mechanism and does not necessarily correlate with the number of tracks present, as some crossings may have gates even if there is only a single track.
