Sample questions

After the first check, how often must cargo securement be re-inspected during a trip?

  1. Every 3 hours or 150 miles, and at each duty status change
  2. Every 8 hours or 500 miles, and at the end of the trip
  3. Only at each fuel stop and at the final destination
  4. Every hour or 50 miles, whichever comes first
Show the answer

A. Every 3 hours or 150 miles, and at each duty status change

The load is re-examined whenever the driver changes duty status and after 3 hours or 150 miles of driving, whichever comes first. Waiting for a fuel stop could leave the load unchecked far too long.

Reference: 49 CFR 392.9(b)(3)

Who may perform the DOT physical examination for an interstate commercial driver?

  1. Any physician licensed in the driver's home state
  2. Only a doctor chosen and employed by the carrier
  3. An examiner listed on FMCSA's National Registry
  4. A state driver-license examiner at the DMV
Show the answer

C. An examiner listed on FMCSA's National Registry

The exam must be done by a medical examiner listed on the National Registry of Certified Medical Examiners. A licensed family doctor who is not on the registry cannot issue a valid certificate.

Reference: 49 CFR 391.43(a); 49 CFR Part 390, Subpart D

A driver's alcohol test shows a concentration of 0.03. What must happen?

  1. The driver may keep driving because the result is under 0.04
  2. The driver is kept off safety-sensitive work for at least 24 hours
  3. The driver must complete the full return-to-duty process
  4. The driver's CDL is disqualified for one year
Show the answer

B. The driver is kept off safety-sensitive work for at least 24 hours

A result of 0.02 or more but less than 0.04 is not a rule violation requiring a substance abuse professional, but the driver must be removed from safety-sensitive functions for at least 24 hours. Carrying on because the result is below 0.04 is the mistake.

Reference: 49 CFR 382.505

A driver who normally works under the short-haul exception sometimes has to keep a log. Paper logs may be used instead of an ELD if logs are needed on no more than how many days?

  1. 8 days in any 30-day period
  2. 10 days in any 30-day period
  3. 15 days in any 30-day period
  4. 8 days in any 60-day period
Show the answer

A. 8 days in any 30-day period

A driver required to keep records of duty status on 8 or fewer days in any 30-day period may use paper logs for those days. Once the driver passes 8 days in the period, an ELD is required.

Reference: 49 CFR 395.8(a)(1)(iii)(A)

A driver comes on duty at 6:00 a.m. and takes a 1-hour off-duty lunch at noon. How does the lunch affect the 14-hour driving window?

  1. The window is pushed back to 9:00 p.m.
  2. The window restarts when lunch ends
  3. The window pauses only if lunch is logged in the berth
  4. The window still closes at 8:00 p.m.
Show the answer

D. The window still closes at 8:00 p.m.

The 14-hour window runs on the clock from the moment the driver comes on duty and ordinary breaks do not stop it, so it closes at 8:00 p.m. Thinking that an off-duty lunch extends the day by an hour is the classic mistake; only a qualifying split sleeper-berth pairing is excluded.
