What can a tanker driver do to reduce the effects of liquid surge?
Correct answer: Brake well ahead of stops with steady pressure and leave more following distance.
Answer options
- ABrake well ahead of stops with steady pressure and leave more following distance Correct
- BLet off the brakes quickly just before the vehicle comes to a full stop
- CSteer sharply while braking so the vehicle works against the moving liquid
Why
To keep the liquid from slamming back and forth, begin slowing long before the stop, hold the pedal pressure even until the vehicle is stopped, and leave a bigger gap ahead. Fast steering movements during braking can tip a tanker over.
