It is important to avoid shifting cargo. The trailer ride can be bumpy and rough. Securing cargo so that it does not shift or 
bounce out of the trailer is imperative. Tie down all loads with properly-sized fasteners. Always secure doors or lids if 
present on your trailer by securing its latch.

MPROPER BRAKING AND STEERING UNDER SWAY CONDITIONS

 

When towing a trailer, you will have decreased acceleration, increased stopping distance, and increased turning radius. 
The trailer will change the handling characteristics of your towing vehicle, making it more sensitive to steering inputs 
and more likely to be have its stability affected in windy conditions or when passed by large vehicles. You will also need 
to adjust driving accordingly, i.e. taking a longer distance to pass and allowing for increased braking distances, etc.  

Taking common-sense measures will be necessary, such as: 

 

Being alert for slippery conditions 

 

Anticipating trailer sway, being ready to reduce speed and using small, trim-like steering adjustments to regain 
control 

 

Check rear view mirrors frequently to evaluate trailer towing and traffic conditions 

 

Using a lower gear when driving downhill or on long grades 

 

Being aware of your trailer height always, especially when approaching bridges and roofed areas.

MPROPER OR INCORRECT COUPLING OF THE TRAILER TO THE HITCH

 

It is critical that the trailer be securely coupled to the hitch, and that the safety chains and emergency breakaway cable 
(electric brakes) and air hoses (air brakes) are correctly attached. Uncoupling of the trailer during transit can lead to a 
serious accident or a fatality.  

Ensure that the pintle hook capacity rating, including installation, is sufficient for the GVWR and the tongue weight of 
the trailer being towed. Make sure that the pintle hook is physically compatible with the trailer drawbar. Compatibility 
information is available from the pintle hook manufacturer. 

Observe the drawbar and pintle hook for wear, corrosion and cracks before coupling. Replace worn, cracked or corroded 
components per the manufacturer's recommendations. 

Ensure the hitch drawbar and pintle hook are installed with grade-8 fasteners and are properly torqued before coupling 
to the tow vehicle. 

Check Prior to Moving 

Do not move the trailer if any of the following conditions appear: 

 

The drawbar is not secured and locked to the pintle hook. 

 

The safety chains are not secured to the tow vehicle. If your trailer detaches from the pintle hook for any reason, 
we have provided safety chains so that coupling of the trailer can still be maintained. Improper rigging of the 
safety chains could result in loss of control coupling. Fasten chains to the frame of the towing vehicle. Do not 
fasten chains to any part of the hitch unless the hitch has special holes or loops specifically designed for that 
purpose. Cross chains underneath hitch and coupler with enough slack to permit turning and to suspend the 
trailer tongue should it become detached. 

 

The trailer jacks are not fully retracted.
