• The vehicle is loaded so the total
   dimensions and total weight on each
   axle are within the limits according to
   the laws in the jurisdiction where the
   vehicle is being operated.

Before unloading

• Move slowly if you must back into a
   position to unload. Before backing in an
   unfamiliar area, get out, look around the
   area and walk the route that you
   will follow.
• You should back the vehicle to the
   driver’s side (left) for better visibility.
   Use the mirrors continually to check
   your position.
• If the vehicle is equipped with a backing
   alarm, make sure it is working. Some
   regulations require a backing alarm
   when vehicles are around workers on
   foot. These alarms must be automatic
   and cannot have a shutoff switch as
   specified in Occupational Health and
   Safety Code 2009.

code visit this web site; http://www.

• Whenever possible, have someone
   guide the vehicle when you are
   unloading. Make sure that you and the
   guide use and understand the same
   hand signals. The guide should always
   be outside and to the rear of the vehicle
   so that he or she is able to see the path
   the vehicle is taking and be seen by the
   driver. The driver should always be able
   to see the guide. Stop if you cannot
   see the guide.

• Remember, even with a guide, you are
   still responsible for all movements
   of the vehicle.
• Check for overhead wires and
   obstructions.
• Do not raise the box to dump unless the
   vehicle is on level ground.

During unloading

• Other vehicles and people must not
   be within the dumping radius of the
   raised box.
• Before dumping into a hopper, get
   out and look to make sure the hopper
   is empty.
• To avoid a tip-over, learn to recognize
   hazardous areas and situations. These
   include soft or uneven surfaces or
   poorly compacted fill.
• The tailgate chain and the angle of the
   truck bed will regulate how fast the
   material flows from the box.
• Check your operator’s manual for
   detailed instructions for unloading.
• Release the tailgate. Be aware that a
   load that is concentrated at the rear of a
   raised box with the tailgate closed can
   tip the vehicle over backwards.
• Do not get into the raised box if the load
   is stuck. Lower the box first.
• If you lose sight of your guide, stop until
   visual contact is regained.
• Once the unloading has been
   completed, lower the box and ensure
   that the tailgate is latched.
