<>— Minimize distractions. Turn off radio and avoid using phone. Buckle up and make sure your passengers are buckled up, too.
— Watch the road for slow-moving or parked vehicles. In fog, use your wipers and defrosters to help improve your visibility.
— Drive with your lights on low beam, because high beams reflect off the fog and reduce visibility.
— Slow down and be aware of speedometer because low visibility can make it hard to tell how fast you're driving. Be sure that you can stop within the distance that you can actually see.
— Use the right edge of the road or painted road markings as a guide, and signal turns well in advance. Brake early to give drivers behind you ample time to react.
— If you must pull off the road, signal first and then drive as far to the right as possible. After pulling to the side, turn on your hazard lights and move away from the vehicle.
