a.Braking only with the trailer brakes
b.Applying the brakes firmly without locking the wheels
c.Pumping the brakes rapidly at all times
d.Using the horn instead of the brakes
解析
Controlled braking means applying the brakes as hard as you can without locking the wheels. Locked wheels cause a skid and loss of steering control. Keeping the wheels rolling lets you brake firmly while still steering, which is important in a heavy, surging tank vehicle.
