Heavy Rain and Hydroplaning

• Before you drive, inspect your windshield wipers and replace them if necessary.
• Turn on your headlights while driving.
• Reduce your speed and maintain a safe distance between your vehicle and the one in front of you; create a "space cushion."
• Avoid sudden braking, which can cause you to slide on the wet pavement. To slow down, take your foot off the gas pedal and brake slowly.
• Avoid areas where water is pooling in travel lanes; if possible, use center lanes and drive in the tracks of the vehicle ahead of you.
• The tires of larger vehicles, like trucks and buses, create spray that can lessen visibility, so don’t follow them too closely.
• Be cautious of hydroplaning. This occurs when a thin layer of water accumulates between your tires and the asphalt and your vehicle loses contact with the roadway. You might suddenly feel your vehicle sliding or drifting because you’ve lost traction. If you feel you are hydroplaning, ease your foot off the gas pedal until you regain traction. Do not brake suddenly. If you are sliding or drifting, gently turn your steering wheel in the direction of your slide.
