What is the purpose of drive direction arrows on a boom or scissor lift?

Drive direction arrows on a boom or scissor lift serve the important purpose of guiding the operator in the intended direction of travel. This visual cue is essential to ensure safe and efficient maneuvering of the lift in various environments, particularly since these machines can have significant weight and size. The arrows help operators navigate around obstacles and maintain awareness of their surroundings while operating the equipment, thereby enhancing safety on job sites.

In contrast, the other options pertain to different aspects of the lift's operational characteristics. The weight limit is crucial for ensuring the lift is not overloaded, and the height capacity is vital for planning how the lift will be used to reach elevations safely. Similarly, the operational speed is an important factor for the safe movement of the lift, but it is not indicated by drive direction arrows. Therefore, drive direction arrows specifically focus on the route of travel, making option A the most relevant and accurate choice.
