Definition
Title 49, Part 395 of the Code of Federal Regulations, which establishes the hours-of-service rules for commercial motor vehicle drivers including daily drive time limits, mandatory rest breaks, and the 60/70-hour weekly limits.
CFR Part 395 is usually more useful as an operating concept than as a buzzword. In real evaluations, the term helps teams explain what a tool should actually improve, what kind of control or visibility it needs to provide, and what the organization expects to be easier after rollout. That is why strong glossary pages do more than define the phrase in one line. They explain what changes when the term is treated seriously inside a software decision.
Why CFR Part 395 is used
Teams use the term CFR Part 395 because they need a shared language for evaluating technology without drifting into vague product marketing. Inside eld compliance, the phrase usually appears when buyers are deciding what the platform should control, what information it should surface, and what kinds of operational burden it should remove. If the definition stays vague, the options often become a list of tools that sound plausible without being mapped cleanly to the real workflow problem.
These terms come up when teams need clearer language around compliance exposure, audit readiness, and how digital workflows replace manual records.
How CFR Part 395 shows up in software evaluations
CFR Part 395 usually comes up when teams are asking the broader category questions behind eld compliance software. Most teams evaluating eld compliance tools start with a requirements list built around fleet size, deployment environment, and day-one integration needs, then narrow by pricing model and operational fit. Once the term is defined clearly, buyers can move from generic feature talk into more specific questions about fit, rollout effort, reporting quality, and ownership after implementation.
That is also why the term tends to reappear across product profiles. Tools like Fleetio, Samsara, Teletrac Navman, and Azuga can all reference CFR Part 395, but the operational meaning may differ depending on deployment model, workflow depth, and how much administrative effort each platform shifts back onto the internal team. Defining the term first makes those vendor differences much easier to compare.
Example in practice
A practical example helps. If a team is comparing Fleetio, Samsara, and Teletrac Navman and then opens Fleetio vs Azuga and Geotab vs Motive, the term CFR Part 395 stops being abstract. It becomes part of the actual evaluation conversation: which product makes the workflow easier to operate, which one introduces more administrative effort, and which tradeoff is easier to support after rollout. That is usually where glossary language becomes useful. It gives the team a shared definition before vendor messaging starts stretching the term in different directions.
What buyers should ask about CFR Part 395
A useful glossary page should improve the questions your team asks next. Instead of just confirming that a vendor mentions CFR Part 395, the better move is to ask how the concept is implemented, what tradeoffs it introduces, and what evidence shows it will hold up after launch. That is usually where the difference appears between a feature claim and a workflow the team can actually rely on.
- Does the platform support the fleet's current hardware and telematics environment?
- How does pricing scale as the fleet grows beyond initial deployment?
- What is the realistic implementation timeline and internal resource requirement?
Common misunderstandings
One common mistake is treating CFR Part 395 like a binary checkbox. In practice, the term usually sits on a spectrum. Two products can both claim support for it while creating very different rollout effort, administrative overhead, or reporting quality. Another mistake is assuming the phrase means the same thing across every category. Inside fleet operations buying, terminology often carries category-specific assumptions that only become obvious when the team ties the definition back to the workflow it is trying to improve.
A second misunderstanding is assuming the term matters equally in every evaluation. Sometimes CFR Part 395 is central to the buying decision. Other times it is supporting context that should not outweigh more important issues like deployment fit, pricing logic, ownership, or implementation burden. The right move is to define the term clearly and then decide how much weight it should carry in the final evaluation.
Related terms and next steps
If your team is researching CFR Part 395, it will usually benefit from opening related terms such as CDL, CMV, CSA Score, and DOT Number as well. That creates a fuller vocabulary around the workflow instead of isolating one phrase from the rest of the operating model.
From there, move into buyer guides like DOT Compliance Checklist: Every Requirement Carriers Must Meet, DOT Safety Rating: Satisfactory, Conditional & Unsatisfactory Explained, and CDL Requirements: How to Get a Commercial Driver's License (2026) and then back into category pages, product profiles, and comparisons. That sequence keeps the glossary term connected to actual buying work instead of leaving it as isolated reference material.
Additional editorial notes
Structure of 49 CFR Part 395
Part 395 is organized into subparts and individual sections that together define the complete hours-of-service framework. Section 395.1 defines applicability and exemptions. Section 395.2 provides definitions for terms like 'adverse driving conditions,' 'on-duty time,' 'sleeper berth,' and 'workday.' Section 395.3 sets the maximum driving time limits for property-carrying vehicles. Section 395.5 covers passenger-carrying vehicles. Section 395.8 governs driver records of duty status (RODS) — the logbook requirement. Section 395.15 covers automatic on-board recording devices (the predecessor to ELDs). Sections 395.20–395.38 establish the ELD mandate, including technical standards, driver instructions, and malfunction protocols. Understanding which section governs which situation is essential for responding to inspection violations.
Section 395.8: Records of Duty Status Requirements
Section 395.8(f) specifies every field a record of duty status must contain: date, total miles driven, CMV power unit numbers, driver's name, name of carrier, main office address, 24-hour period starting time, name of co-driver, total time in each duty status, total hours, and shipping document number or name and address of shipper and commodity. A 'form and manner' violation under 395.8(f)(1) is cited when any required field is missing or illegible. These violations carry a CSA severity weight of 2 — low individually, but they accumulate quickly across a fleet and can push the HOS BASIC percentile above intervention thresholds. ELDs pre-populate most required fields automatically, which is the primary operational argument for ELD adoption beyond pure compliance.

Operational Scenario: Using Part 395 During a Roadside Inspection
How an officer reads an ELD log against Part 395
During a Level I inspection on I-40 in Oklahoma, a compliance officer reviews a driver's ELD log for the past 7 days. The officer is specifically checking: (1) whether the driver has had 10 consecutive off-duty hours before each driving period per 395.3(a)(1); (2) whether any driving period extends beyond 11 hours per 395.3(a)(3)(i); (3) whether the driver took a 30-minute break after 8 cumulative driving hours per 395.3(a)(3)(ii); and (4) whether cumulative on-duty time for the 7-day period exceeds 60 hours per 395.3(b)(1). If the ELD shows a 30-minute gap in driving at hour 8 but the status shows 'on-duty not driving' rather than 'off-duty' or 'sleeper berth,' the break does not satisfy the 395.3(a)(3)(ii) requirement. This is a common finding — drivers who use on-duty-not-driving status for meal breaks unknowingly invalidate their 30-minute break compliance.
- Print or download a copy of 49 CFR Part 395 from eCFR.gov and review it annually — FMCSA amends Part 395 periodically and changes take effect without broad notification to carriers
- Train dispatchers on the specific section citations used in violation notices — when a driver is cited under 395.3(a)(3)(ii), dispatchers need to understand what the 30-minute break rule actually requires vs. what the driver was doing
- Audit ELD duty-status entries for drivers who regularly log 'on-duty not driving' during meal breaks — if they're relying on those periods as 30-minute break compliance, they're exposed
- When building a HOS training program for drivers, use the actual CFR section numbers alongside plain-language explanations — drivers who understand the citation language are better equipped to contest errors during inspections
- Review Section 395.1(e) exemptions annually to confirm which, if any, apply to your operation — the short-haul exemption, adverse driving conditions extension, and oilfield exemptions each have specific conditions that must be documented
