Maryland CDL Combination Vehicles: Rollover Test 2026

The Maryland CDL combination rollover skid jackknife test targets the three failures most likely to put a long rig on its side. This 2026 drill explains how a high center of gravity and fast cornering cause rollovers, how a trailer skid develops into a jackknife when the drive wheels or trailer wheels lose grip, and what a driver does the instant traction slips.

You will study why keeping the cargo low and centered reduces rollover risk, why braking in a curve is so dangerous for a combination, and how to recover when the trailer starts to swing. Understanding rollover, skid, and jackknife dynamics is what keeps a Maryland combination driver upright when conditions turn against them.

Since the count of combination questions is set at the state level, verify the number in your newest Maryland CDL Manual rather than guessing. Work this rollover, skid, and jackknife drill until the warning signs are obvious to you, and your CDL combination skills will be sharper for the effort.
