Read explanations, practical guides and industry perspectives on the questions drivers and operators face.
California truck drivers facing wildfire closures should verify safe, legal detours and remaining driving time before continuing. Federal HOS exceptions depend on specific conditions, not delay alone. Confirm vehicle and permit restrictions, distinguish unexpected adverse conditions from declared relief work, and keep accurate logs. Personal conveyance cannot be used to continue commercial delivery.
California’s 55 mph limit applies to vehicles listed in CVC section 22406, not every commercial truck. Covered vehicles generally use a signed designated lane or the right-hand traffic lane. On divided highways with four or more lanes in one direction, they may also use the adjacent lane. Passing does not permit farther-left lanes or speeds above 55 mph.
Drivers pressured to exceed HOS or operate unsafe equipment should document the current log, defect, or health concern and request a lawful alternative. FMCSA coercion generally requires a violating request, the driver’s objection, and a threat or negative action. Preserve original evidence and track the separate 90-day FMCSA and 180-day OSHA STAA deadlines.
Cargo securement must be checked before departure, within the first 50 miles, and again at the earliest duty-status change, three-hour point, or 150-mile point. Drivers should inspect both tension and damage, verify working load limits and commodity-specific rules, and stop safely for loose equipment, unusual noise, door deformation, or seal-related concerns.
