What should an operator do if the grader starts to skid?

Answer: B — Reduce speed and adjust the blade angle for better traction

When a grader starts to skid, the most effective response is to reduce speed and adjust the blade angle for better traction. This action helps restore control by allowing the operator to re-establish grip on the surface. Lowering the speed minimizes the risk of losing control further, while adjusting the blade angle can help the grader find better footing by engaging with the material more effectively. When a grader is skidding, momentum can exacerbate the situation; hence, accelerating would likely increase the skid and lead to a more dangerous situation. Sharp turns in response to skidding can also cause the grader to roll or tip over, which would compromise safety and lead to potential equipment damage. Ignoring the skid as a normal occurrence disregards the importance of vehicle control and could lead to accidents or unsafe conditions. Therefore, reducing speed and adjusting the blade is the optimal choice for maintaining control and ensuring the safety of both the operator and the equipment.
