Which of the following is a pre-start check for controls on a forklift?

Ensuring that the lights are working is a critical pre-start check for forklift operations. This is because functioning lights are essential for visibility and safety, particularly when operating in low-light conditions or in areas where visibility might be compromised. Proper lighting helps the operator to see the work environment clearly and also makes the forklift more visible to pedestrians and other vehicles, reducing the risk of accidents.

Pre-start inspections are crucial to maintain safety standards and operational efficiency. While checking for flat tires, load capacity, and inspecting the operator seat are important aspects of overall forklift safety and readiness, they do not specifically pertain to the operational controls of the forklift, which is the focus of this question. The operational controls include the steering, braking, and signaling systems, which are directly affected by the functionality of the lights.
