Addressing vehicle loads on public highways.

This bill requires all vehicles operating on public highways to secure loads of dirt, sand, or gravel to prevent spills or hazards, unless at least six inches of freeboard (uncovered space) is maintained in the vehicle bed. Drivers must cover such loads or clean debris from vehicles (like mud on tires) before traveling on paved roads, and must immediately clean up any spilled materials that endanger others. Violations range from minor infractions for simple failures to more serious offenses causing property damage (misdemeanor) or bodily harm (gross misdemeanor). Exceptions include maintenance vehicles dropping sand for traction or sprinkling water to clean highways.
