Remember, keeping a proper following distance from other vehicles, you can decrease risk of accident. Keep safe distance yourself. Never assume another driver will share space with you!
Most rear end accidents are caused by tailgating. To have enough space between your vehicle and the vehicle ahead, use the "three-second rule".
When the vehicle ahead of you passes a certain point, such as a sign, count "one-thousand-one, one-thousand-two, one-thousand-three." This takes about three seconds. If you pass the same point before you finish counting, you are following too closely.
At faster speeds the distance should be greater. Sometimes you will need more than a "three-second" cushion. Give yourself a "four-second or more" cushion.
When you are towing a vehicle or following behind another towed vehicle or a three-axle truck, stay at least 300 feet behind it. The rule does not apply when you are: In a business or residence district; on a highway with two or more lanes for traffic moving in the same direction; overtaking and passing the vehicle ahead.
Keep a space cushion on each side of your car – not only ahead. Don't drive in another driver's blind spot. The other driver may not see your car and could change lanes and hit you.
