If a tank vehicle begins to skid or the rear trailer starts to swing out, what is the safest response for the driver?

In a tank-vehicle skid, abrupt inputs are the enemy. Hard braking can deepen the skid and, combined with surge and a high center of gravity, can lead to a rollover or jackknife. The driver should ease off the accelerator, avoid slamming the brakes, and steer smoothly in the direction needed to keep the vehicle tracking straight, then gradually regain control. Because liquid surge can keep pushing the rig even after the wheels respond, recovery takes patience and gentle steering. Prevention — slowing for curves, smooth braking, and extra following distance — is far more reliable than trying to recover from a skid already underway.
