c. Industrial tractors. The following operating rules
are applicable to industrial tractors:
(1) Weaving the train is dangerous and will
not be permitted.
(2) Operators must not attempt to haul
excessive loads that cause wheel slippage and loss of
traction. Also, operators will ensure that loads are
secure.
(3) When negotiating a turn into a road or
aisle, allow sufficient time to get into position to make
the turn and allow for proper clearance of the last trailer.
(4) Operators and supervisors should limit the
height of the load on the first trailer behind the tractor.
The height will not obstruct the rear view of the operator
nor create a hazard to the operator in the event material
accidentally shifts or falls.
(5) When a permanent passenger seat is
provided, one passenger may be carried. No person will
be allowed to occupy a temporary seat or ride on any
part of the machine.
