About the Florida CDL uncoupling test
Breaking down a set of doubles has its own order, and reversing it carelessly is how equipment ends up damaged. This Florida CDL doubles and triples uncoupling test walks the sequence: park straight on level ground, set the parking brakes and secure the units, uncouple the rear trailer from the dolly first, then unhook the dolly from the trailer in front of it, and only then work back toward the tractor.
The cdl doubles and triples uncoupling practice test for 2026 also covers lowering landing gear before releasing anything, chocking wheels where trailers have no spring brakes, disconnecting and stowing dolly air and electrical lines, closing the shut-off valves that are now at the end of the string, and securing safety chains so they never drag.
Florida sets its own length for the doubles and triples endorsement knowledge exam, so check your Florida CDL Manual for the exact number of questions. Practice this Florida CDL uncoupling drill in the same order every time and the procedure will hold up even at the end of a long shift.
Every question traces back to the Florida CDL Manual - skim the right-of-way and signs chapters before your retake.
