Modernized CDL skills test vs the old one: what changed

Updated October 2026 · Written from the state CDL manuals

The modernized CDL skills test is the updated national model that most states have switched to. The biggest changes are in the vehicle inspection: you may bring a blank checklist as a memory aid, you usually inspect one axle instead of the whole truck, and the air brake check has four parts instead of three. Which version you get depends on your state, and in a few states on the test site.
  • 26 states confirmed on the modernized test, 6 still on the older one, 1 running both.
  • 18 more not yet confirmed: check the state manual before you book.
  • The air brake check is still all-or-nothing in both versions.

What changed

Older testModernized test
ChecklistGenerally no memory aids (Washington’s old guide said so outright)A blank checklist as a memory aid, with no extra markings or writing
How much of the truckThe whole vehicle, or a part the examiner picks on the dayUsually one axle, no crawling under the vehicle (Delaware, Washington)
Air brake checkThree parts: leakage, low air warning, spring brakesFour parts: governor cut-out added (Delaware)
Basic control skillsThe older set of backing maneuversA new set, phased in by state (Maine moves in September 2027)

What did not change: you still point at each part, name it and say what you are checking. The checklist lists the items; it does not say the words for you. The full checklist and what to say.
