Why are stimulants such as amphetamines a dangerous answer to fatigue?
- A.They are only dangerous in cold weather
- B.They make the truck use more fuel
- C.They mask tiredness briefly but wear off suddenly, and their use can disqualify a commercial driver
- D.They are safe if bought over the counter
Correct answer
C. They mask tiredness briefly but wear off suddenly, and their use can disqualify a commercial driver
Why
Stimulants create a false sense of alertness while judgment and reaction time stay impaired, and the crash when they wear off can be sudden. Illegal drug use, including amphetamines not lawfully prescribed, is disqualifying for CDL holders.
