What should you do after driving through a flood?
- A Carry out an emergency stop
- B Drive in a low gear with the footbrake lightly applied
- C Avoid braking until the brakes have dried out
- D Pump the footbrake when approaching hazards
Why this is the answer
If you have to drive through a flood, do so with caution. Once out of the flood, you need to test your brakes to make sure they're working properly. To do this, check what's behind you, then drive in a low gear with the brakes gently applied.
Why the other answers don't fit
- A
- Carry out an emergency stop — An emergency stop on wet brakes is a test you may fail at the worst moment.
- C
- Avoid braking until the brakes have dried out — Avoiding the brakes leaves them wet for the first hazard that needs them.
- D
- Pump the footbrake when approaching hazards — Pumping at a hazard means finding out they are wet when it is already too late.
