- Drive Axles: Ensures tandem drive groups remain at or below the 34,000 lb legal cap.
- Trailer Axles: Verifies sliding tandem placement to keep rear weight under 34,000 lbs.
- Gross Vehicle Weight: Confirms the overall combination weight does not exceed the standard 80,000 lb federal highway maximum.
