Bridge law: (CAUTION: This is a super simplified version!!) The maximum
allowed gross vehicle weight in reduced if the distance between axles
is not enough. Thus a 5-axle truck/trailer is normally limited to
80,000 lbs GVW., but if it's a really short trailer it will be
overweight if the GVW is 80,000 lbs.

Practical reason. The truck can dump _without_ unhitching from the
