Mitigating the risk of hydroplaning primarily involves adjusting driving behavior, particularly in wet conditions. Reducing speed is crucial because faster speeds increase the likelihood of tires losing contact with the roadway due to water buildup. When tires are moving more slowly, they have a better chance of displacing water and maintaining grip on the surface. Avoiding sudden movements—such as abrupt steering, hard braking, or rapid acceleration—also plays a significant role. These actions can destabilize the vehicle and increase the chances of the tires losing traction. Smooth, controlled maneuvers help ensure that the vehicle stays in contact with the road surface, reducing the risk of hydroplaning. The other options may seem like potential strategies, but they do not effectively address the issue of hydroplaning. For instance, accelerating to cut through water can worsen the situation by increasing the chance of tires losing grip. Similarly, while staying in the center of the lane can help maintain a straight path, it does not fundamentally reduce the risk of hydroplaning, especially if speed is not managed. Keeping windows open for ventilation does not have any impact on the vehicle's ability to remain stable on wet surfaces. Therefore, the correct approach is to prioritize speed reduction and smooth driving techniques to minimize
