About the Hawaii CDL uncoupling test
The Hawaii CDL combination uncoupling quiz walks through separating a tractor from a trailer without dropping a load or damaging equipment. You review positioning the rig, lowering the landing gear, disconnecting the air and electrical lines, releasing the fifth-wheel lock, and easing the tractor clear in the proper order.
These 2026 combination questions test whether you understand why the landing gear must fully support the trailer first, how to secure the disconnected lines, and what can go wrong if you rush the sequence. Smooth uncoupling is the flip side of coupling and just as important to a Class A driver.
The exact number of uncoupling questions is a state decision, so verify it in your Hawaii CDL Manual before you count on it. Practice this drill until the steps flow in the right order every time, then wrap up the remaining combination topics.
Every question traces back to the Hawaii CDL Manual - skim the right-of-way and signs chapters before your retake.
