To avoid a crash, you have to bring your tanker to a stop in a hurry. Which way of braking is correct?
Correct answer: Brake with the controlled or stab method.
Answer options
- ALock the wheels with the pedal and keep them locked
- BBrake with the controlled or stab method Correct
- CRely on the emergency brake alone
Why
With controlled braking you press as hard as you can without locking the wheels; with stab braking you brake fully, let up when the wheels lock, and brake again once they roll. Both stop the vehicle quickly without leaving the wheels locked, so you can still steer.
