What this covers

Sample questions

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)

An ELD automatically switches to driving status once the vehicle reaches a set speed threshold. What is the highest that threshold may be?

  1. 1 mph
  2. 5 mph
  3. 10 mph
  4. 15 mph
Show the answer

B. 5 mph

The ELD must record driving once the vehicle is moving at a threshold of no more than 5 mph. The vehicle is treated as stopped again only after speed falls to zero and stays there for 3 consecutive seconds.

Reference: 49 CFR Part 395, Subpart B, Appendix A, 4.3.1.2

A truck in driving status has not moved for 5 consecutive minutes and the driver ignores the ELD's prompt. What does the ELD do after 1 more minute?

  1. Changes the status to off duty
  2. Changes the status to sleeper berth
  3. Keeps recording driving until the engine is shut off
  4. Changes the status to on duty, not driving
Show the answer

D. Changes the status to on duty, not driving

After 5 minutes without motion the ELD asks the driver to confirm driving or pick another status; with no answer within 1 minute it switches to on duty, not driving. It never selects off duty or sleeper berth on its own, because those must be the driver's choice.

Reference: 49 CFR Part 395, Subpart B, Appendix A, 4.4.1.2
