Below is a sample of the regulations for truck tarp coverings and containment in Alaska, California, Hawaii, Oregon, and Washington.


While Alaska may have the shortest list of regulations to make note of, it is still important to recognize that all materials must be contained and/or confined to prevent any motor vehicle loaded with sand, gravel, rock or similar substances from ever polluting the highway and causing hazardous conditions to other drivers.

California & Hawaii

Both California and Hawaii have an extensive list of truck tarp regulations which impact the types of materials allowed on the highway and the specifics of how materials should be contained. For example, both states have major penalties for moving vehicles that contain anything except clear water or feathers from live birds and are not properly covered.


Oregon provides exemptions to the truck tarp regulations for a variety of causes, one example being the specific ownership of the road that a sifting and leaking loaded vehicle is operating on. However, most of the materials transported in a moving vehicle do require tarps or coverings to prevent those particles from sifting out onto major roads.


In Washington, the penalty for not following explicit commercial truck covering laws involves criminal charges in the first degree for a gross misdemeanor. It is imperative to understand that in Washington, and most states, the obstruction to another vehicle or person due to negligence is a punishable crime.
