Question: Driving while drowsy is:

Answer options:

  • Safe with coffee ✅ As dangerous as driving impaired
  • Only a problem at night
  • No different from rested

Correct answer: As dangerous as driving impaired

Explanation: Driving while tired is as dangerous as driving impaired because fatigue severely slows reaction times, diminishes coordination, and impairs decision-making in ways very similar to alcohol consumption. Temporary fixes like drinking coffee only mask symptoms briefly without restoring cognitive function, and drowsiness can strike during daytime hours, making the other options incorrect. SAAQ guidelines emphasize that sleep is the only effective remedy for fatigue and treat drowsy driving as a major safety hazard equivalent to impairment. On the Quebec knowledge test, expect questions highlighting that physical wellness and adequate rest are critical safety requirements, and that artificial stimulants cannot replace sleep.
