View All PlansThe pre-trip inspection is a procedure to ensure a commercial vehicle is in roadworthy condition before it begins a journey. You must perform a pre-trip inspection at the start of your shift. During the licensing process, you must also correctly perform this procedure as part of the CDL skills tests. We’ll help you understand what the pre-trip inspection is about, but first, you should read the official Commercial Driver License Manual (District of Columbia CDL Handbook). Section 11 (Vehicle Inspection) describes this topic in detail and tells you what to look for when inspecting your vehicle.
Our District of Columbia CDL Pre-Trip Inspection Practice Tests are designed to help you familiarize yourself with the components you need to check and the terminology used by examiners during the CDL skills tests. The practice test that you’re about to take includes questions similar to those you will encounter on the official General Knowledge Test. Each question has multiple answer choices, but only one is correct. “Officer Frank,” your AI coach, will help you find the correct answer by providing hints. These hints will nudge you in the right direction, so don’t hesitate to ask “Officer Frank” for assistance whenever you need it.
