Urban or city driving involves a variety of complex driving situations. Spaces are limited; you deal with lots of cars, bicyclists, pedestrians, buses and one-way streets. If you are driving too fast and don't pay attention, you can hit a person, parked car, or make a sudden stop or maneuver which could cause other drivers to collide with your vehicle. In city driving, you should be prepared to stop or slow down suddenly. Cover braking provides a smooth transition from acceleration to braking and is effective for slowing in reduced stopping distances. During heavy traffic it is very important to maintain a proper distance between vehicles in your front, side, and rear zones. Also be aware of brake lights, since it is very common for the flow of traffic to suddenly slow or even come to a complete stop.
