Front Towing
A vehicle can fall from a car-carrier if it
isn't
adequately secured. This can cause a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains or
steel cables before it is transported.
Don't use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components.
Before hooking up to a tow truck, be sure to read
all the information in "Towing Your Vehicle" earlier in
this section.
