§393.71
Coupling Devices and Towing Methods, Driveaway-Towaway
Operations
Question 1: May a fifth wheel be considered as a
coupling device when towing a semi-trailer in a driveaway-towaway
operation?
Guidance: Yes. §393.71(g) requires
the use of a tow-bar or a saddle-mount. Since a saddle-mount performs the
function of a conventional fifth wheel, the use of a fifth wheel is consistent
with the requirements of this section.
