What is the maximum number of driving hours a driver may log in a single shift under FMCSA's 14-hour window rule?
11 hours
12 hours
10 hours
13 hours
FMCSA regulations allow a driver to operate a commercial motor vehicle for up to 11 hours of driving within a 14-hour on-duty window. This limit is designed to reduce fatigue and improve safety on the road.
After 8 consecutive hours of driving, a driver must take a break of at least how many minutes?
30 minutes
60 minutes
15 minutes
45 minutes
Under the hours-of-service rules, a driver must take at least a 30-minute break after 8 cumulative hours of driving. The break must be uninterrupted and counted as off-duty or on-duty not driving time.
Which device is required to automatically record hours of service?
Tachograph
Hours-of-service mobile app
Electronic Logging Device
Paper logbook
An Electronic Logging Device (ELD) is mandated by FMCSA to automatically record a driver's hours of service, eliminating the need for paper logbooks and improving accuracy.
What is the maximum on-duty time allowed within the 14-hour window?
12 hours
14 hours
13 hours
15 hours
The 14-hour window rule limits a driver's on-duty time (driving plus other work) to 14 consecutive hours after coming on duty following 10 consecutive off-duty hours.
When fueling or performing vehicle inspections, which duty status must a driver select on the ELD?
Driving
Off-duty
On-duty not driving
Sleeper berth
Fueling or conducting vehicle inspections do not involve driving but are work-related activities, so they must be recorded as "On-duty not driving" in the ELD.
Under the 70-hour/8-day rule, what is the maximum on-duty hours allowed before a driver must take a 34-hour restart?
65 hours
70 hours
75 hours
60 hours
The 70-hour/8-day rule caps a driver's total on-duty hours at 70 within any eight consecutive days. To regain hours, the driver must take a 34-hour restart.
A driver takes three breaks of 10 minutes each during a shift. Does this satisfy the required 30-minute qualifying break?
No, the 30-minute break must be continuous
Yes, if the breaks are within every 4 hours
Yes, because total break time is 30 minutes
No, breaks must be off-duty only
The qualifying 30-minute break must be one continuous rest period; splitting it into multiple shorter breaks does not meet FMCSA requirements.
Under adverse driving conditions, how many additional driving hours is a driver allowed?
3 hours
4 hours
1 hour
2 hours
FMCSA allows a driver to extend driving time by up to 2 additional hours when encountering adverse driving conditions, but total driving cannot exceed 13 hours and the on-duty window cannot exceed 16 hours.
Which duty status should be used when operating a vehicle for personal errands under ELD rules?
Personal conveyance
Personal use
On-duty not driving
Off-duty
Personal conveyance status is specifically for movements that are unrelated to commercial operations, such as running personal errands outside of work duties.
Which of the following data elements is NOT automatically recorded by an ELD?
Vehicle weight
Date and time
Engine hours
Vehicle miles
ELDs automatically record vehicle miles, engine hours, date, time, and location. Vehicle weight is not a data element captured by ELDs.
A driver's log shows 15 hours on-duty within the 14-hour window. Which violation does this represent?
Incomplete log entries
Exceeding the duty window
Missed required break
Exceeding driving time
Logging 15 hours on-duty in a 14-hour window violates the duty window rule, which restricts total on-duty time to 14 consecutive hours after coming on duty.
After using a 34-hour restart, which hours are reset to zero?
Both driving and on-duty hours
On-duty hours only
Driving hours only
Break hours
A 34-hour restart resets both driving and on-duty hour accumulations, allowing the driver to begin a new cycle under FMCSA hours-of-service rules.
What is a key strategy for drivers to avoid hours-of-service violations?
Plan rest breaks ahead of time
Drive faster to save time
Extend shifts when needed
Ignore ELD alerts
Proactive planning of rest breaks and on-duty periods helps drivers stay within limits and reduces the risk of triggering hours-of-service violations.
Which ELD feature provides a visual representation of a driver's duty status over time?
Graph grid
Diagnostic report
Data transfer
Manufacturer data
The graph grid on an ELD screen shows a timeline of a driver's duty status changes, making it easier to spot gaps or potential violations.
When is it permissible for a driver to edit an ELD record for a mistake?
Only after 30 days
Anytime after the shift
Within 7 days
Within 24 hours of the event with annotations
ELD rules allow drivers to make corrections within 24 hours of the original entry, provided they add an annotation explaining the change.
To use the adverse driving conditions extension, what is the maximum extra time allowed to complete the 11-hour driving limit?
1 hour
3 hours
2 hours
4 hours
Under adverse driving conditions, drivers may extend their driving window by up to 2 hours, but the total driving time cannot exceed 13 hours and the duty window cannot exceed 16 hours.
How can a driver split the required 10-hour off-duty period under the sleeper berth provision?
5 hours in sleeper berth + 5 hours off-duty
7 hours in sleeper berth + 3 hours off-duty
9 hours in sleeper berth + 1 hour off-duty
8 hours in sleeper berth + 2 hours off-duty
The sleeper berth provision allows a 10-hour off-duty period to be split into at least 8 hours in the sleeper berth plus at least 2 hours off-duty, which still counts as a valid reset.
What is the maximum air-mile radius and on-duty window under the short-haul exemption?
100 air miles and 12-hour window
200 air miles and 16-hour window
150 air miles and 14-hour window
250 air miles and 18-hour window
The short-haul exemption allows drivers to operate within a 150 air-mile radius and remain on-duty for up to 14 hours without ELD logging requirements.
What condition must be met when using a 34-hour restart to reset cycle limits?
Must be spent entirely in the sleeper berth
Must include two periods between 1 a.m. and 5 a.m.
Must include 24 hours off-duty plus 10 hours in sleeper berth
Any consecutive 34 hours off-duty
A valid 34-hour restart must include two periods between 1 a.m. and 5 a.m., ensuring drivers have rest during typical nighttime hours to effectively reset their cycle.
If an ELD malfunctions, what is the correct procedure for the driver?
Record only engine hours manually
Discontinue driving permanently
Use paper logs until fixed within 8 days
Continue driving without logging
When an ELD malfunctions, drivers must revert to paper logs (or another automatic logging method) and have the device repaired or replaced within eight days.

Cheat Sheet

  1. Understand the 11-Hour Driving Limit - Hit the highway knowing you can drive a maximum of 11 hours after at least 10 consecutive hours off duty. This rule keeps you fresh, fights fatigue, and helps you arrive safely at your next destination.
  2. Comprehend the 14-Hour On-Duty Limit - Your work clock starts the moment you step on duty and runs for 14 straight hours, regardless of breaks. Once those hours are up, you must clock out and give yourself a proper rest to stay compliant and alert.
  3. Recognize the 30-Minute Break Requirement - After eight cumulative hours of driving, you need at least a 30-minute break to recharge. Stepping away from the wheel helps you refuel, stretch, and tackle the next leg with renewed focus.
  4. Learn the 60/70-Hour Limit - You can't drive after you've logged 60 hours on duty in 7 consecutive days or 70 hours in 8 consecutive days. This weekly cap ensures you enjoy adequate downtime and return to the road refreshed.
  5. Explore the Sleeper Berth Provision - Split your mandatory 10-hour off-duty period into two segments - one must be at least 7 consecutive hours in the sleeper berth. This flexibility lets you nap smartly and stay within the rules while maximizing rest.
  6. Identify ELD Compliance Requirements - Electronic Logging Devices must connect directly to your engine, allow secure driver log-ins, and present data in a standardized format. Meeting these specs keeps your logs accurate, audit-ready, and hassle-free.
  7. Understand Personal Conveyance Rules - When you're off duty, personal conveyance lets you move your commercial vehicle for non-business reasons without affecting your hours of service. Use this time wisely for rest stops, meals, or returning home.
  8. Recognize Agricultural Exemptions - During planting and harvesting seasons, certain farm operations within a 150-air-mile radius enjoy HOS exemptions. This relief helps agricultural drivers manage busy seasons without complex log juggling.
  9. Learn About ELD Documentation Requirements - Always carry an ELD user manual, instruction sheets, and spare blank RODS graph-grids. Having these on hand makes roadside inspections smooth and keeps you world-class compliant.
  10. Understand Penalties for Non-Compliance - Missed breaks or inaccurate logs can lead to fines, out-of-service orders, and damaged safety ratings. Staying on top of HOS rules protects your wallet, reputation, and license.
