- Compliance Monitoring Active — 24/7/365 Automated Oversight
Stay compliant with FMCSA Hours of Service regulations through proactive monitoring of driver logs, ELD records, and HOS limits. Identify violations early, reduce CSA risks, avoid costly penalties, and keep your fleet operating safely and efficiently.
Under 49 CFR 395, the Hours of Service regulations establish the following core limits for property-carrying CMV drivers:
The 11-Hour Driving Limit: Drivers may operate their vehicle for a maximum of 11 hours after 10 consecutive hours off duty. Exceeding this limit is a direct HOS violation.
The 14-Hour Driving Window: Drivers cannot drive beyond the 14th consecutive hour after coming on duty, following 10 consecutive hours off duty. This window includes both driving and non-driving on-duty time. Once 14 hours have elapsed, the driver may not drive again until they have taken a 10-hour off-duty break — regardless of how many hours of driving time remain.
The 30-Minute Break Requirement: After 8 cumulative hours of driving without at least a 30-minute interruption, drivers must take a break. This break can be satisfied by any non-driving period of 30 consecutive minutes, including on-duty not-driving time.
The 60/70-Hour Limit: Property-carrying drivers may not drive after accumulating 60 hours on duty in 7 consecutive days, or 70 hours in 8 consecutive days. A 34-hour restart restores the full weekly limit.
Sleeper Berth Provisions: Drivers using a sleeper berth may split their 10-hour off-duty period into a 7-hour minimum in the berth combined with at least 2 hours outside — provided the two periods together total 10 hours and neither period counts against the 14-hour driving window.
Any of these limits can be violated in ways that generate separate, distinct citations — each carrying its own fine and CSA point weight.
FMCSA can fine motor carriers up to $19,246 per Hours of Service violation. Individual violations — an 11-hour rule violation, a 14-hour window violation, a missed 30-minute break — each carry their own penalty, meaning a single driver’s log from a single day can generate multiple separate fines. Beyond the per-violation fines, HOS violations accumulate in the Hours of Service Compliance BASIC in FMCSA’s Safety Measurement System, where they affect the carrier’s percentile ranking against peers for 24 months.
A carrier at or above the 65% intervention threshold in the HOS Compliance BASIC receives an alert status, flagging the carrier for FMCSA interventions including warning letters, targeted roadside inspections, and onsite investigations. Carriers with one or more BASIC alerts have been shown to have significantly higher future crash rates than those without alerts. The 14-hour rule is the most commonly violated provision, generating the highest volume of HOS citations at roadside. CDL Manager’s monitoring specifically flags approaching 14-hour window exhaustion across active drivers, catching the issue before the violation occurs.
The Electronic Logging Device mandate — fully in effect for nearly all regulated carriers — requires CDL drivers to use certified ELDs to automatically record Hours of Service data. ELDs replaced paper logs for the vast majority of drivers and created a direct digital pipeline between driver duty status and the data available at roadside inspections. In 2025, FMCSA formally added ELD violations to the CSA scoring system, directly impacting the HOS Compliance BASIC.
ELD violations that count against the HOS Compliance BASIC include: operating without a functioning ELD, ELD malfunctions that go unresolved, failure to transfer ELD data to an inspector, and operating on paper logs when not exempt. These violations can result in an out-of-service order for the driver and add violation weight to the carrier’s BASIC measure. CDL Manager tracks ELD compliance status across your fleet — monitoring for malfunction events, data transfer failures, and unresolved ELD issues that need to be corrected before they appear as violations at roadside.
Not every HOS compliance issue is a hard violation of the driving time limits. A significant category of HOS citations involves log discrepancies — situations where the ELD record doesn’t match supporting documents, or where the record doesn’t accurately reflect the driver’s actual duty status. Form and manner errors — incorrect or missing entries on the log, improper location entries, missing carrier information, or duty status entries that don’t reconcile with other records — generate separate violation citations.
Supporting document review is a formal part of HOS compliance auditing. Safety investigators conducting a compliance review of the HOS BASIC will request logs alongside supporting documents — fuel receipts, toll records, dispatch records, delivery receipts, and any other documents that can be cross-referenced against the ELD record. Discrepancies between ELD records and supporting documents are a critical violation trigger. CDL Manager’s HOS monitoring includes review of supporting documentation alignment, flagging discrepancies before they become audit findings.
Individual HOS violations are costly. Patterns of HOS violations are catastrophic. A carrier whose CSA data shows repeated HOS violations by the same driver, or systemic violations across a route or terminal, is presenting FMCSA investigators with evidence of a management control problem — not just an isolated driver error. That distinction matters: a pattern of noncompliance elevates a violation from a standard roadside citation to a Critical Violation trigger in an investigation.
CDL Manager’s trend reporting analyzes HOS compliance data across your fleet to identify repeat issues before they reach the threshold that triggers escalated enforcement action. Which drivers are consistently approaching the 14-hour limit? Which routes generate the most log discrepancy alerts? Which drivers show patterns of late 30-minute break compliance? Trend data gives you the operational intelligence to address root causes — scheduling adjustments, route changes, driver coaching — rather than just responding to violations after the fact.
Continuous oversight of every driver’s duty status, driving time, and cycle hours in real time
Malfunction events flagged immediately with resolution workflows initiated
Real-time notifications when a driver approaches or exceeds any HOS limit, or when a log inconsistency is detected
Continuous tracking of 11-hour, 14-hour, and 60/70-hour limits for every active driver
Log entry errors and missing required information identified and flagged for correction
Cross-reference of ELD records against available supporting documents to catch discrepancies before audits
Pattern analysis across drivers, routes, and time periods to identify systemic compliance problems
Complete, organized ELD and log data available for FMCSA compliance reviews on demand
Every HOS violation recorded at a roadside inspection enters the SMS and affects the carrier’s HOS Compliance BASIC percentile for 24 months. Violations are time-weighted — those recorded within the past six months carry three times the weight of violations from 13–24 months ago. That means a cluster of violations from a bad stretch can keep a carrier in elevated-alert territory for two years, even if the underlying issues have been corrected.
The only way to improve the HOS Compliance BASIC is to stop accumulating violations — and the only way to stop accumulating violations systematically is to monitor compliance before violations occur. CDL Manager provides the monitoring infrastructure that makes that possible: real-time visibility into every driver’s hours, proactive alerts before limits are reached, and the documentation trail to demonstrate to investigators that your compliance program is functioning as required.
