Controlled braking is primarily utilized to maintain vehicle stability and ensure that it remains in a straight line during the braking process. This technique involves applying the brakes progressively and steadily rather than slamming them, which can cause the vehicle to skid or lose traction. When a driver employs controlled braking, they manage the deceleration of the vehicle carefully, allowing for better steering control and preventing the wheels from locking up. This is particularly important in larger vehicles, which may have different handling characteristics compared to passenger cars.

The other choices do not accurately capture the purpose of controlled braking. While reducing tire wear can sometimes be a positive byproduct of controlled braking, it is not the main purpose. Speeding up the vehicle is the opposite of what controlled braking is intended for. Stopping quickly in an emergency is more relevant to "panic braking" rather than controlled braking, which focuses on smooth, gradual slowing of the vehicle.
