Quick Answer
HOS and ELD violations can lead to fines, an out-of-service order that parks the driver for hours, and CSA points that stay on a carrier's record for up to 24 months. Serious violations — like driving beyond the 11-hour limit or running a revoked device — carry the heaviest penalties, and repeated issues raise audit risk and insurance costs.
Key Takeaways
- Penalties range from citations and fines to out-of-service orders.
- No proper record of duty status can mean 10 hours out of service (8 for passenger carriers).
- Violations add CSA points that follow the carrier for up to 24 months.
- Nearly all common violations are preventable with an ELD that alerts you early.
The three ways an HOS violation costs you
- Fines and citations. Amounts vary by violation severity, from moderate citations to substantial penalties for egregious or repeat cases.
- Out-of-service orders. For no proper RODS, an inspector can place a driver out of service for 10 hours (8 for passenger carriers) — you can't move until the clock clears.
- CSA score damage. Violations add points under the Hours of Service Compliance category of the FMCSA's Safety Measurement System, and they can remain for up to 24 months — affecting insurance premiums and broker relationships.
Most common ELD / HOS violations
Violation | What triggers it | How to avoid it |
|---|---|---|
Driving over 11 hours | Losing track of drive time | ELD countdown alerts |
Blowing the 14-hour window | Detention, delays | Plan a sleeper split |
Missing the 30-min break | Continuous driving past 8 hrs | Break reminders |
No/incorrect RODS | Log errors, device issues | Registered, working ELD |
Running a revoked device | Not checking FMCSA list | Verify device status |
Falsified logs | Editing duty status | Never edit driving segments |
Why "just driving a little over" is expensive
The 11-hour and 14-hour limits are hard lines. Going over — even by a short margin — is a recordable violation that can add CSA points, and because those points linger for up to two years, one bad day can raise your insurance and hurt your standing with brokers who screen carriers by safety score. Log falsification is treated even more seriously and was a named enforcement focus in 2026 roadside checks.
How to avoid ELD violations
- Use the countdown clocks. A good ELD shows time left on each limit so you stop before you cross a line.
- Turn on proactive alerts. Warnings before you hit the 11-hour, 14-hour, and 30-minute thresholds prevent most violations.
- Plan sleeper splits for detention. Don't let a dock wait eat your window — see sleeper berth rules.
- Confirm your device is registered. Check it against the FMCSA registered and revoked lists.
- Never edit driving segments. Annotate, don't falsify — ELD data is cross-referenced against fuel and dispatch records.

FAQ
Q: How much is an HOS violation fine?
A: It depends on the violation and whether it's a repeat or egregious case — amounts range widely, and the most serious violations reach into the thousands. Confirm current penalty amounts with FMCSA, as they're periodically adjusted.
Q: How long do HOS violations stay on my record?
A: CSA points from HOS violations can remain on a carrier's Safety Measurement System record for up to 24 months.
Q: Can an ELD prevent violations by itself?
A: It can't drive for you, but its countdown clocks and proactive alerts prevent the majority of accidental violations — most HOS citations come from losing track of time, which is exactly what an ELD is built to stop.
