Which factor is listed as a cause of tipping sideways due to speed and turning?

• A. Coated floor
• B. Driver fatigue
• C. Driving too fast
• D. Overinflated tires

Answer: (C)

The tendency to tip sideways when turning is driven by speed creating lateral forces during a turn. As you steer, the forklift must lean into the curve, and the inertia of the moving mass pushes outward. If you’re going too fast, that outward (centrifugal) force makes the resultant line of gravity and inertia move toward or beyond the edge of the forklift’s base of support, increasing the risk of tipping on its side. This is why driving too fast in a turn is the most direct factor linked to sideways tipping.

Other options don’t describe the same mechanism as clearly. A coated floor might affect traction and handling, but tipping due to speed in a turn is about the dynamic forces on the vehicle, not just surface type. Fatigue can impair judgment and reaction, but it isn’t the immediate cause of a tip during a turn. Overinflated tires change handling in general, but again, the specific risk of tipping sideways from speed turning is most directly caused by operating too fast.

To stay safe, slow down before and during turns, keep the load low and close to the forklift, and avoid sharp turns or lifting when turning.
