Direct Answer
The Hours of Service BASIC measures violations related to driver fatigue regulations: specifically, whether drivers comply with FMCSA's limits on daily and weekly driving time. Common violations include falsified or missing logs, ELD malfunctions, and exceeding driving time limits. HOS violations are serious because they indicate driver fatigue risk, which is a primary factor in large truck fatal crashes.
What the Hours of Service BASIC Measures
The HOS BASIC tracks violations of 49 CFR Part 395: the federal Hours of Service regulations. These rules set maximum driving and on-duty times for CMV operators to manage driver fatigue.
The three core HOS rules:
| Rule | Property-Carrying Drivers |
|---|---|
| 11-Hour Driving Limit | May drive maximum 11 hours after 10 consecutive hours off duty |
| 14-Hour On-Duty Limit | May not drive beyond 14th hour after coming on duty |
| 60/70-Hour Limit | May not drive after 60/70 hours on duty in 7/8 consecutive days |
Additional rules cover the 30-minute break requirement, the 34-hour restart provision, and the sleeper berth split option.
Regulation Context
- Primary CFR: 49 CFR Part 395: Hours of Service of Drivers
- ELD mandate: 49 CFR Part 395.8 and 395.15: Electronic Logging Devices (required for most CMV operators since 2019)
- Record of Duty Status (RODS): Drivers must maintain RODS for the current day and previous 7 days
Common HOS Violations and Severity Weights
| Violation | CFR Reference | Severity Weight | OOS Condition? |
|---|---|---|---|
| ELD malfunction / not using required ELD | 395.8 | 7–10 | Conditional |
| Driving after 11-hour limit | 395.3(a)(1) | 10 | Yes |
| Driving beyond 14-hour window | 395.3(a)(2) | 8 | Yes |
| Exceeding 60/70-hour limit | 395.3(b) | 7 | Yes |
| Falsification of RODS | 395.8(e) | 10 | Yes |
| Missing or incomplete RODS | 395.8 | 5–7 | Conditional |
| No 30-minute break | 395.3(a)(3) | 5 | No |
Falsification is treated as the most serious HOS violation and can trigger CDL disqualification.
CSA / BASIC Impact
- BASIC affected: Hours of Service Compliance
- Severity weights: 5–10; driving-time violations and falsification score highest
- OOS conditions: Driving after exceeding 11-hour or 14-hour limits triggers driver OOS
- Time on record: 24 months
- Threshold: Carriers above the HOS alert threshold face elevated FMCSA scrutiny
The HOS BASIC is particularly sensitive for carriers that operate long-haul routes where drivers push limits or where ELD data is not actively monitored by safety managers.
Corrective Action Steps
- Pull the ELD data for the cited driver and review the full duty-status log for the preceding 7 days.
- Identify whether the violation was an isolated incident or a pattern. A single mistake is a training issue. A pattern is a process or culture issue.
- Brief the driver immediately. Review the specific regulation violated and the consequences.
- Audit your ELD provider's settings. Are HOS alerts configured? Are dispatchers notified when a driver is approaching their limit?
- Review dispatch practices. Are loads being assigned in ways that pressure drivers to push HOS limits?
- Update your HOS policy and have drivers sign an acknowledgment.
- For ELD malfunctions: Follow the ELD malfunction procedure per 395.34: annotate the record, revert to paper logs, and notify the ELD provider.
- Document all steps in a corrective action file.
Evidence Checklist
- ☐ Inspection report
- ☐ ELD data export for the cited driver (current day + 7 days prior)
- ☐ Driver statement
- ☐ Dispatcher log showing load assignment timeline
- ☐ HOS policy document (signed by driver)
- ☐ Driver retraining record
- ☐ ELD provider alert configuration screenshots
- ☐ Corrective action plan
Prevention Tips
Configure ELD alerts proactively. Your ELD system can notify dispatch and safety managers when a driver is 60, 30, and 0 minutes from their driving time limit. If these alerts aren't active, turn them on today.
Train dispatchers, not just drivers. HOS violations often start at dispatch when unrealistic delivery windows are assigned. Dispatchers need to understand HOS rules as well as drivers do.
Review ELD data weekly, not just after violations. Active monitoring catches HOS drift before it becomes a violation.
Don't treat the 14-hour rule as elastic. Some drivers treat the 14-hour window as a driving limit rather than a hard cutoff. Make sure your fleet understands that on-duty-not-driving time counts toward the 14 hours.
Frequently Asked Questions
Q: Does the HOS BASIC apply to exempt short-haul drivers? Short-haul drivers who qualify for the short-haul exemption are not required to use an ELD and have different HOS rules. However, violations of the short-haul rules still count against the HOS BASIC if found during inspection.
Q: What happens if our ELD has a malfunction during an inspection? Per 49 CFR 395.34, when an ELD malfunctions, the driver must note the malfunction and record RODS on paper. The carrier must repair or replace the ELD within 8 days. Inspectors can place the driver OOS if paper logs are also unavailable.
Q: Can a carrier be penalized for violations the driver didn't report? Yes. Carriers have an obligation to monitor driver compliance and cannot claim ignorance when ELD data was available.
