SECTION 1 - SAFETY PRECAUTIONS
1-4 – Triple-L-Trailer – 3121224
Unsafe Load Distribution
Uneven load distribution can cause tire, wheel, axle or
structural failure. Be sure your trailer is properly loaded. A
proper weight distribution is equal, right to left; and cre-
ates a tongue weight that is in the proper range for stable
trailer handling (between 10-15% of the total weight of the
cargo and the trailer). Towing stability also depends on
keeping the center of gravity as low as possible. Load
heavy items on the floor and over the axles, but do not
exceed the axle load rating (GAWR). When loading addi-
tional items, be sure to maintain even side-to-side weight
distribution and proper tongue weight.
MAKE CERTAIN THAT THE TONGUE WEIGHT IS WITHIN THE
ALLOWABLE RANGE. BE SURE TO DISTRIBUTE THE LOAD
FRONT-TO-REAR TO PROVIDE PROPER TONGUE WEIGHT, DIS-
TRIBUTE THE LOAD EVENLY, RIGHT AND LEFT, TO AVOID TIRE
OVERLOAD AND KEEP THE CENTER OF GRAVITY LOW.
Shifting Cargo
Since the trailer “ride” can be bumpy and rough, you must
secure your cargo so that it does not shift while the trailer
is being towed.
TIE DOWN ALL LOADS WITH PROPER SIZED FASTENERS,
ROPES, STRAPS, ETC. IF YOUR TRAILER IS ENCLOSED OR
EQUIPPED WITH AN OPTIONAL TAILGATE, THE DOORS OR TAIL-
GATE MUST BE SECURELY LATCHED BEFORE TOWING THE
TRAILER.
Inappropriate Cargo
If your trailer is designed for specific cargo, only carry that
cargo in the trailer. A utility trailer must not be used to
carry certain items, such as people, containers of hazard-
ous substances or containers of flammable substances.
DO NOT TRANSPORT PEOPLE ON OR INSIDE THE TRAILER. THE
TRANSPORT OF PEOPLE PUTS THEIR LIVES AT RISK AND MAY
BE ILLEGAL.
DO NOT TRANSPORT FLAMMABLE, EXPLOSIVE, POISONOUS OR
OTHER DANGEROUS MATERIALS IN YOUR TRAILER.
EXCEPTIONS: FUEL IN THE TANKS OF EQUIPMENT BEING
HAULED; FUEL STORED IN THE TANK OF AN ON-BOARD GEN-
ERATOR
Inoperable Brakes, Lights or Mirrors
Be sure that all of the lights on your trailer are functioning
properly before towing your trailer. Lights on a trailer are
controlled via a connection to the tow vehicle, generally a
multi-pin electrical connector. Check the trailer taillights by
turning on your tow vehicle headlights. Check the trailer
brake lights by having someone step on the tow vehicle
brake pedal while you look at the trailer lights. Have some-
one activate the tow vehicle’s turn signals to check the
trailer’s turn signal lights.
If your trailer has electric brakes, your tow vehicle must
have an electric brake controller that sends power to the
trailer brakes. Before towing the trailer on the road, you
must operate the brake controller while trying to pull the
trailer in order to confirm that the electric brakes operate.
While towing the trailer at less than 5 mph, manually oper-
ate the electric brake controller in the tow vehicle cab. You
should feel the operation of the trailer brakes.
BEFORE EACH TOW CHECK THAT THE TAILLIGHTS, BRAKE
LIGHTS AND TURN SIGNALS WORK AND CHECK THAT THE
ELECTRIC BRAKES WORK BY OPERATING THE BRAKE CON-
TROLLER INSIDE THE TOW VEHICLE.
