What does Short Haul mean?

For Canadian truckers, short haul refers to a commercial vehicle operating within a relatively short distance of a home terminal during a day (i.e., up to 160 km) and returning to that home terminal at the end of each shift. This is in contrast to tractor-trailer units driven much farther, such as interstate, between cities or cross-border, known as long haul or OTR (over the road).
