Weather, Visibility & EmergenciesStandalone practice
You drive on a highway in heavy rain. Water has pooled in low spots in the lanes ahead. What is the best way to keep your tires from hydroplaning?
A approaches several patches of pooled water during heavy rain on a highway. Water is visible in all three lanes, and no lane or avoidance path is selected.
Correct answer: Slow down well before you reach the areas of pooled water
Why
When the tires hydroplane, they act like water skis and you can lose steering and braking control. Slow down as soon as rain, snow, sleet or ice begins, because a wet road makes stops longer. If the car starts to slide, ease off the pedals and steer smoothly where you want to go.
