Alcohol

The Driver's Code said each stage can only be as good as the one before it. Alcohol is the lesson where that chain doesn't just weaken — it fails at every link simultaneously. Worse, it disables the one stage that would notice. This lesson gives you Kenya's actual legal limits (there are two, and one of them is zero), what rising alcohol does to a body in order, the remedies that don't work and why, and the parts of the law that catch people who thought they were being careful.

In this lesson you'll learn

  • Kenya's actual legal limits — the private-driver figure and the zero limit for PSV/commercial/school drivers — with the penalties.
  • Why alcohol is uniquely dangerous: it degrades all three stages of the driver's code at once, and removes the judgement needed to notice.
  • The impairment ladder: what happens to the body at rising blood-alcohol levels.
  • The myths that kill: coffee, cold showers, and "I feel fine" — and the single thing that actually sobers you.
  • Why the same drink affects the same person differently on different days — and why "counting drinks" fails.
  • The complicity rule: how serving or lending can make you liable too.
  1. 1. The Law: Two LimitsState Kenya's two drink-driving limits and the penalty, and recognise the procedural safeguards a valid reading requires.
  2. 2. Why Alcohol Is Uniquely DangerousExplain how alcohol degrades all three stages at once, and why the stage that would notice fails first.
  3. 3. The Impairment LadderDescribe the progression of impairment with rising blood alcohol, and identify why the lowest rung is the most dangerous for driving.
  4. 4. The Myths, and Why Counting Drinks FailsState the only thing that reduces blood alcohol, and explain why "knowing your limit in drinks" is not a workable strategy.
  5. 5. Liability Beyond the WheelRecognise the situations that create liability without driving, and state the narrow Kenyan complicity rule accurately.
