Theory exams often check whether you understand that stopping distance grows with speed and worsens in poor conditions—not only whether you can quote a number. The Safety and Road Rules theory books in the learner book collection cover speed limits and defensive attitudes; combine that mindset with clear reasoning under pressure.
Think of total stopping distance as two main parts: the distance you travel while you perceive and react, plus the distance needed to brake. Higher speed increases both—especially braking distance. Stay within posted limits and adjust for traffic, weather, and visibility—speed limits are ceilings, not targets.
Sample questions (reasoning)
The correct choice is highlighted in each list and spelled out under Correct answer.
Exact figures depend on vehicle and conditions; the exam tests understanding of the relationship, not laboratory measurement.
