When an ELD is required
Most property-carrying CMV drivers in interstate commerce who must prepare RODS need an ELD unless they qualify for an exception.
Remember: General rule: if RODS are required often, expect ELD unless an exception applies.
Key concepts
Study Guide
Core topics every driver and trainer should understand before moving to the interactive tools.
When paper logs are allowed
Paper may be allowed for limited paper-RODS use, driveaway-towaway operations, pre-2000 vehicles, or temporary ELD malfunction situations.
Remember: Paper is an exception, not the default, when an ELD is required.
ELD malfunction steps
The driver must notify the carrier, reconstruct missing RODS, use paper if the ELD cannot accurately record HOS, and repair/replace the ELD within the allowed time.
Remember: Paper after malfunction is temporary. Track the date and notify the carrier.
Short-haul basics
Short-haul drivers may use time records instead of RODS when they stay within the required radius and meet all short-haul conditions.
Remember: If they break the short-haul limits, RODS may be required for that day.
Hours-of-Service Basics
RODS are the proof. Hours-of-Service rules are what the driver is trying to prove they followed.
How long can they drive in a 24-hour period?11 hours
A property-carrying driver may drive up to 11 hours after taking 10 consecutive hours off duty.
How long can they work in a 24-hour period?14-hour window
After coming on duty, the driver may not drive after the 14th consecutive hour. Other work may still be on-duty, but driving is not allowed after the window closes.
When is a break required?30 minutes
A driver needs a 30-minute interruption after 8 cumulative hours of driving without a qualifying break.
Weekly work limits60 / 70 hours
A driver may not drive after 60 hours on duty in 7 days, or 70 hours on duty in 8 days, depending on the carrier schedule.
How do they reset weekly hours?34-hour restart
Taking 34 or more consecutive hours off duty can restart the 60/70-hour calculation.
Remember: A logbook is not just paperwork. It shows whether the driver stayed within the driving limit, on-duty window, break rule, and weekly work limits.
