Safe Driving Behaviour and Defensive Driving
What this domain covers
Safe Driving Behaviour and Defensive Driving tests hazard perception, observation, speed choice, distraction, fatigue and the mental habits that prevent collisions. The exam rewards anticipation: noticing a risk early and creating time and space to deal with it.
The defensive system
Use MSPSL on approach to any hazard: Mirrors (check behind), Signal (tell others), Position (choose the safest lane or road position), Speed (adjust before the hazard), Look (assess and decide). Scan 12–15 seconds ahead and check mirrors every 5–8 seconds. Keep an escape route and assume other road users may not see you.
Distraction and fatigue
Mobile phone use while driving is illegal in most jurisdictions, even hands-free increases cognitive load. Eating, smoking, arguing and adjusting sat-nav can all take your eyes off the road. Fatigue signs include yawning, heavy eyes, drifting and missed signs. The only reliable remedy is to stop and rest; opening a window or turning up music is temporary and unsafe.
Speed choice
The speed limit is a maximum, not a target. Choose a speed that lets you stop within the distance you can see to be clear. Stopping distance rises with the square of speed: doubling speed roughly quadruples braking distance.
Worked example
On a rural road you see a ball roll into the road ahead. What is the defensive response? Ease off the accelerator, cover the brake, reduce speed and scan for a child who may follow the ball. Do not swerve blindly into the opposite lane. Reasoning: the ball is an early cue of a hidden hazard; slowing buys time and reduces impact severity.
Traps that cost marks
- Treating the speed limit as a target in poor visibility.
- Relying on mirrors alone and forgetting blind-spot checks.
- Driving through fatigue because you are close to home.
- Assuming a driver who has seen you will give way.
- Fixating on one hazard and missing the second one.
Key points
- Use MSPSL: mirrors, signal, position, speed, look.
- Scan 12–15 seconds ahead; mirrors every 5–8 seconds.
- The speed limit is a maximum for ideal conditions.
- Fatigue is cured by stopping and resting, not by fresh air.
- Phone use impairs driving even when hands-free.
- Anticipate hidden hazards from early cues.
