Questions from employers in this region
Caterpillar's Danville facility has a significant CDL distribution fleet — can you manage their random program?
Yes. We coordinate FMCSA Part 382 random pool management and on-site collections for Caterpillar's CDL distribution fleet at the Danville facility, handling selection notification and scheduling to minimize disruption to shipping operations.
Our Danville-based carrier runs routes into North Carolina. Do regulations differ across the state line?
Federal DOT regulations apply uniformly across both states for regulated employees. For non-DOT company-policy programs, Virginia and North Carolina have different state-level considerations. We coordinate collections for cross-border carriers and can address multi-state program questions.
