Decision Making on Roads
Every journey is a series of small decisions. Better decisions build safer journeys.
Synopsis
Road users make hundreds of decisions during every journey. Better judgement, anticipation and situational awareness reduce exposure to hazards and improve safety outcomes.
Why this matters
You can't control other road users. You can control the quality of your own decisions.
Expected outcome
You will apply defensive habits — scanning, anticipating, giving space — to reduce risk on every journey.
Learning objectives
After completing this lesson learners should be able to:
- Improve road judgement
- Understand defensive behaviour
- Anticipate hazards
- Make informed decisions
Why Decisions Matter
Every decision on the road affects safety — the speed you choose, where you place the vehicle in the lane, when to overtake, which gap to accept, how much distance to leave, which route to take. Small decisions, made hundreds of times, add up to your safety profile as a road user.
Defensive Behaviour
Defensive road users scan continuously, anticipate hazards, remain patient, adjust to changing conditions and — critically — expect that other road users will make mistakes. Defensive driving is not timid driving; it is driving that stays one step ahead of what could go wrong.
Anticipation
Safe decisions are prediction problems. Ask four questions constantly: What could happen next? Who around me could be at risk? How much space do I have? What alternatives do I have if this situation changes? Answering these before you need to act is what makes anticipation work.
Reading the road ahead
Traffic ahead slows suddenly. A defensive driver has already eased off, opened the following gap and glanced in mirrors before the brake lights turned red — the reaction was set up seconds earlier.
Real-world scenarios
Overtake on a narrow road
You intend to overtake a slower vehicle on a narrow two-lane road with intermittent oncoming traffic.
→ What should you consider first before committing?
Show suggested response
Available visibility and space — including sight distance ahead, the gap you need to complete the manoeuvre and any oncoming vehicles. Without adequate visibility and space, no overtake is safe, regardless of the speed of following traffic.
Key takeaways
- Better decisions reduce risk.
- Anticipation buys reaction time.
- Defensive behaviour protects everyone on the road.
- Expect — and plan for — other road users' mistakes.

Q1. Which best characterises defensive behaviour on the road?
- Continuously anticipating hazards and planning for others' mistakes ✓
- Assuming other road users will always behave correctly
- Following closely to discourage lane changes into your gap
- Overtaking whenever there is any opening
Defensive driving means expecting error and leaving room to react — not assuming everyone else will do the right thing.
Q2. Which factor most directly influences whether an overtake is safe?
- The direction of the wind
- Available visibility and space to complete the manoeuvre ✓
- The colour of the vehicle being overtaken
- How full the fuel tank is
Sight distance and available space determine whether you can complete the overtake before any oncoming or hidden hazard becomes a problem.
Q3. Why is anticipation important for road safety?
- It helps drivers save fuel
- It makes the ride more comfortable
- It allows earlier responses to developing hazards ✓
- It increases average travel speed
Anticipation turns split-second reactions into planned actions — the earlier you see a hazard, the more options you have.
