What should drivers do to avoid sudden surface changes while on a side slope?

Driving at moderate speeds on a side slope is crucial because it provides better control over the vehicle, allowing the driver to respond quickly to sudden changes in surface conditions such as rocks, loose gravel, or mud. When navigating slopes, the risk of losing traction is higher, and speed can significantly impact the vehicle's stability. Maintaining a moderate speed enables the driver to assess the terrain more effectively, anticipate any potential hazards, and make necessary adjustments without risking the vehicle's stability or safety. This approach promotes cautious navigation, especially in potentially slippery or uneven areas, which are commonly encountered on airport properties or emergency response scenarios.
