Whenever an escort is required

  • only the weight-based Chapter 6/superload tiers are modeled. Confirm dimension-only loads directly with CDOT.

Each example changes one dimension from a legal 8′6″ wide, 13′6″ high, 75′, 80,000 lb tractor-trailer. Real moves often combine several. “Set by permit” means Colorado decides that case on the permit itself. Permits can add conditions of their own, so check yours before you move.
