- Q28Safe driving
Why should you avoid sudden harsh braking on a sand-covered desert road?
- ASand greatly reduces tyre grip, making it easy for the wheels to lock up and the vehicle to skid uncontrollably
- BHarsh braking is safe on sand because the loose surface absorbs the stopping force
- CBraking on sand damages the tyre sidewalls but does not affect stopping distance
- DABS compensates fully for sand and makes braking distance the same as on tarmac
