Which driving maneuver could increase the risk of skidding?

Sudden braking in a turn can significantly increase the risk of skidding because it disrupts the vehicle's balance and traction. When a driver brakes abruptly while turning, the weight shifts suddenly, which can lead to a loss of grip on the road surface. This is especially true on wet, icy, or uneven roads, where the tires may lose their ability to maintain traction. In such scenarios, the vehicle may slide or skid, making it challenging for the driver to control the vehicle.

In contrast, gradually increasing speed on a straight road, maintaining a constant speed, and using turn signals in advance do not inherently carry the same risk of causing skidding. These actions allow for more control and stability while driving, reducing the likelihood of losing traction and veering off course. Thus, the correct focus is on understanding how sudden maneuvers, particularly during turns, compromise vehicle stability.
