Which maneuver should be avoided while driving a forklift?

Reversing without looking is a significant safety risk when operating a forklift. This maneuver should always be avoided because it greatly increases the likelihood of collisions or accidents. A forklift operator must be aware of their surroundings at all times, especially when reversing, as this is typically a blind spot. Checking for pedestrians, other vehicles, and obstacles ensures that the operator maintains a safe work environment and prevents injuries or property damage.

In contrast, the other options, while they may carry risks, do not inherently denote an unsafe practice as clearly as reversing without looking does. Maneuvering with a full load can be done safely with proper training and techniques, driving on ramps is manageable with caution, and loading while moving might be permissible under certain conditions as long as it’s done carefully. The key takeaway here is that safety awareness encompasses constant vigilance, especially in potentially hazardous movements like reversing.
