Safe Driving Practices and Defensive Driving

This domain tests whether you drive to survive other people's mistakes. Defensive driving means scanning ahead, keeping space, signalling early and choosing a speed that lets you stop within the distance you can see to be clear.

Core habits

  • Use the mirror-signal-manoeuvre routine before changing direction or speed.
  • Keep at least a two-second gap in dry conditions; double it to four seconds in rain or poor visibility.
  • Look far ahead and check mirrors regularly; identify escape routes.
  • Adjust speed for wet roads, gravel, darkness, bends and school zones.
  • Avoid distractions; a phone call or text removes attention from the road.

Worked example

You are following a truck at 30 mph on a wet road with a two-second gap. You increase the gap to four seconds. Reasoning: wet tyres have less grip and stopping distances rise; the extra second gives you time to react if the truck brakes suddenly. The gap is measured from a fixed point, not from the truck's bumper.

Traps that cost marks

  • Tailgating because the vehicle ahead is 'too slow'.
  • Using high beam in fog, which reflects back and reduces vision.
  • Assuming a green light or clear road means no hazard.
  • Driving at the posted limit when conditions demand slower.
  • Signalling after braking or after starting the manoeuvre.
