Assured clear distance ahead

Assured clear distance ahead means that when you're driving your car, you should always make sure to keep a certain amount of space between you and the car in front of you. This amount of space needs to be enough so that if that car stops suddenly, you have enough time to stop your car safely without hitting the other car. Keeping your distance from the car in front of you is also helpful for allowing other cars to pass safely or for you to turn into another lane.
