Question 20

To determine the answer, we recall traffic safety statistics: In 2014, 10% of 15 - 19 - year - old drivers in fatal crashes were distracted, and this age group had the highest proportion of distracted drivers. So the statement is true.

• Option a: Regular breaks on long drives reduce fatigue.
• Option b: Good posture helps avoid fatigue - related discomfort.
• Option c: Fresh air can keep a driver alert.
• Option d: Allowing eyes to lose focus is not a countermeasure; it can increase fatigue or reduce driving safety.

• Depressants (a) slow the central nervous system.
• Stimulants (b) arouse the central nervous system, heightening senses.
• Narcotics (assuming option c, though not fully visible) typically depress or have other effects, not heightening senses via CNS arousal.

Answer:

a) True
