Smoking and preparing to smoke while driving:

  1. Do not affect driving abilities.
  2. Help maintain driver alertness.
  3. Are distracting activities. ✓
  4. Are not distracting activities.

Answer: C. Are distracting activities.

Smoking and preparing to smoke while driving are distracting activities that take your attention away from the road.

Why this is the answer

The handbook lists smoking among the activities that can distract your attention, alongside eating, drinking, and adjusting controls. It explains that distracted driving happens when any activity shifts your full attention from the driving task, and its tips say to avoid smoking, eating and drinking while you drive. Since smoking and getting ready to smoke pull your attention and hands away from driving, they count as distractions.

Why the other answers are wrong

Remember it

If it takes a hand, your eyes, or your mind off the road, the handbook counts it as a distraction, and smoking is on that list.
