To ensure that your physical condition does not cause you to drive in an unsafe manner, you should:

  1. Keep physically fit and have regular physical examinations.
  2. Know the effect of any medicine on your driving ability.
  3. Drive within your physical limitations.
  4. All of the above. ✓

Answer: D. All of the above.

All of the above: keep physically fit and get regular check-ups, know how any medicine affects your driving, and drive within your physical limits.

Why this is the answer

The handbook's physical health section says anything that affects your physical or mental condition can impair your driving. It tells you to get regular vision, hearing, and general physical check-ups, to get treatment for illnesses and stay off the road when sick, and to ask your doctor or pharmacist how any prescribed medication can affect your driving. Knowing your medicine's effects and staying within what your body can handle follow from that same warning that your condition shapes how safely you drive.

Why the other answers are wrong

Remember it

Picture three boxes to tick before you turn the key: body checked, medicine understood, limits respected.
