Driver Behaviour, Ethics, and Psychology
Core concepts
Safe driving is as much psychological as technical. Candidates should understand the effects of fatigue, stress, aggression, and alcohol on judgement; the dangers of road rage and competitive driving; and the ethics of courtesy, patience, and protecting vulnerable road users. Perception and reaction time worsen with tiredness, and drivers systematically underestimate their own impairment.
Behaviour and risk
Defensive driving means assuming others may make mistakes and leaving room to react. Tailgating, weaving, and horn abuse increase risk and are treated as aggressive behaviour. Peer pressure and time pressure push drivers to take risks; recognising this is part of hazard perception. Alcohol, drugs, and some medicines impair coordination and judgement even below legal limits.
Traps in questions
- Feeling "fine" does not mean fit to drive; fatigue and alcohol impair self-assessment first.
- Courtesy is not weakness: yielding to a vulnerable road user is the correct answer in most ethics questions.
- Aggressive responses to another driver's mistake escalate risk.
- Emotions (anger, stress) change perception of speed and distance.
Rule of thumb
When a question asks for the "best" behaviour, choose the option that reduces risk for the most vulnerable person and keeps a margin of safety - not the option that asserts a right of way.
