Which description of controlled braking is accurate?

Correct answer: It keeps the vehicle moving straight while still letting you steer if needed.

Answer options

  1. AIt is required whenever you have to turn sharply while braking
  2. BIt keeps the vehicle moving straight while still letting you steer if needed Correct
  3. CIt involves letting the wheels lock up, then easing off the brakes

Why

Controlled braking means squeezing the brakes as hard as you can without locking the wheels, which keeps the vehicle tracking straight and preserves your ability to steer. Locking the wheels and then releasing is stab braking, and if you need to make a large steering correction you should ease off the brakes first.
