Cargo loading and securement - Oklahoma

In Oklahoma, no vehicle may be driven or moved on any highway unless constructed or loaded to prevent any of its load from dropping, sifting, leaking, blowing, or otherwise escaping.

No person may operate on any highway, any vehicle with any load unless the load and any covering are securely fastened to prevent the covering or load from becoming loose, detached, or in any manner a hazard to other users of the highway.

Any vehicle loaded with sand, cinders, or other loose material susceptible to blowing or otherwise escaping must have the load covered to prevent the blowing or escaping of the load.

This requirement does not apply to the following:

• The dropping of sand for the purpose of securing traction;
• The sprinkling of water or other substances to clean or maintain the roadway; or
• Trucks loaded with livestock, poultry, hay, or agricultural products, provided the truck is constructed or loaded to prevent it from escaping.
