Ohio CDL Doubles & Triples: Uncoupling Doubles/Triples Test 2026

Taking a set of doubles or triples apart safely is a deliberate, ordered task, and the uncoupling section of the Ohio CDL doubles and triples test confirms you can do it right. The goal is to separate each unit without letting a trailer or dolly roll free.

The sequence generally works from the rear forward: secure the rearmost trailer, close the correct air shut-off valves, disconnect and stow the lines, unlock the fifth wheel, and pull clear of the converter dolly before lowering landing gear and chocking wheels as needed. Setting the trailer brakes and chocking before you release any coupling keeps everything still while you work in an Ohio yard in 2026.

Practice the uncoupling order in the Ohio CDL Manual until it is automatic. Because the number of doubles and triples questions is not fixed, verify the current 2026 total in your Ohio commercial driver license manual first.
