Braking distance refers to the amount of space it takes for a vehicle to come to a complete stop.  This distance varies greatly between different types of vehicles.  A train, for instance, takes almost a mile to stop.  The length, weight, and speed of a train make it difficult to stop.  The general rule of thumb for a standard sedan is one car length.  Again, the weight and speed of vehicle will play a major role in its ability to stop quickly.  The heavier and faster a vehicle is moving relates to the amount of inertia that vehicle has.  The greater the inertia the harder the brakes must work to halt the vehicle.
