Pre-Trip Inspection Study & Checklists

  • Pre Trip Inspection Checklist & Video – Most states require students to pass a pre-trip inspection test before obtaining a commercial driver’s license. Use our CDL pre-trip inspection checklist as your study guide.
  • Class A Pre Trip Inspection Practice Test – sample questions about checking items in the engine compartment, driver door fuel area, trailer, in the cab and all others.

Trucking Terminology

  • Trucker’s Lingo – Each profession has its own set of words and phrases that help members of the profession communicate with each other effectively. A successful CDL training program will introduce new drivers to the terminology they will use as professional truck drivers. This special “trucker language” is just another part of the lifestyle that makes professional truck driving so rewarding.
