Texas CDL General Knowledge: Vehicle Inspection Test 2026

Inspection is the single most heavily tested subject in the entire general knowledge pool, which makes this Texas CDL vehicle inspection test the drill worth repeating most often. The 2026 Texas CDL inspection practice test separates the three inspections a commercial driver performs: before the trip, during the trip, and after the trip when the vehicle inspection report is written.

Questions dig into what actually disqualifies a vehicle from service. Cracked or loose wheel lugs, oil and coolant leaks, a mirror that will not hold adjustment, worn tread depth, a missing warning device, and any brake defect are all classic items. You should also know which items must be checked while the engine runs and which are checked with the engine off.

The seven-step inspection routine gives the topic its structure, and following it in order is far easier than memorizing a list. Read the inspection chapter of the Texas CDL Manual and treat this Texas CDL inspection drill as your rehearsal.
