Say Your Pre-Trip Like You’ve Done It for Years.

This page focuses only on your Pre-Trip Inspection: exterior, under-hood, steering, suspension, brakes, wheels, coupling, and trailer. Use the stop-light system so you always hit the critical red items while still sounding polished.

Goal: Be able to walk a truck and talk non-stop using DMV-style language without freezing, pausing, or guessing.

Red: Miss = Possible fail
Yellow: Important details
Green: Confidence add-ons

  • No leaks — hoses, lines, seals, engine, air system.
  • No abrasions, bulges, or cuts — tires, hoses, rubber parts.
  • All lug nuts present and tight — wheels / rims.
Yellow · High-Value Details

  • Suspension: No shiny metal, no shifted or missing parts.
  • Brakes: No more than 1/4" play, no contaminants.

  • No illegal welds or modifications on safety components.
  • In good working condition for safe operation of the vehicle.
