What 395.15(b) means in plain language
FMCSR 395.15(b) requires that onboard recording devices—commonly electronic logging devices (ELDs) or older approved automatic recording systems—maintain and display certain identifying and operational information. When an officer inspects your truck, they need to see that your device clearly shows required data like the device manufacturer, serial number, and certification status.
This isn't about how you use the device to record hours. It's about the device itself having the right labels and information visible. If your ELD is missing a manufacturer name, certification number, or other required identifier, you can be cited even if your actual hours records are perfectly kept.
Think of it like a vehicle registration sticker: the rule exists to prove the equipment itself is legitimate and approved for use.
What our enforcement data actually shows
Across our 13 million+ inspection records, 395.15(b) is extremely rare. All-time, we show just 152 citations for this violation since tracking began. In the last 12 months, we recorded zero citations, and in the last 90 days, zero citations—meaning this code is not generating active enforcement pressure on the road right now.
When citations have been issued, only 3 out of 149 drivers were placed out of service, yielding a 2.0% OOS rate. That's dramatically lower than the all-FMCSR average of 31.4%, reflecting that this is treated as a documentation or labeling issue rather than a safety-critical violation. Among all 3,036 FMCSR codes, 395.15(b) ranks #1294 by citation volume, placing it in the bottom tier of enforcement priorities.
Who gets cited most
Our inspection records do not show state-level granularity for this code due to its extremely low citation count. However, the carriers cited most frequently include US XPRESS INC and 11266047 CANADA INC, each with 2 citations in our all-time database. Several other carriers—A S D TRANS INC, KIP TRANSPORTATION LLC, and others—also appear with single citations. The low volume means no clear pattern emerges; this violation is scattered rather than concentrated in any fleet or geography.
How severe is this compared to similar codes
395.15(b) sits in the Hours of Service category alongside far more heavily enforced codes. For example, 395.24 (HOS ELD Form and Manner) has generated 106,486 citations with a 0.0% OOS rate. Meanwhile, 395.8A1-HOSP (Failing to have a record of duty status using the prescribed method) carries 52,266 citations and a 92.9% OOS rate—indicating that actual failure to maintain hours records is treated much more seriously than device labeling defects.
Another peer code, 395.8(a)(1) (Not using the appropriate method to record hours), has 39,561 citations and a 93.2% OOS rate. In that context, 395.15(b)'s 152 all-time citations and 2.0% OOS rate show it is a marginal enforcement issue. Officers are far more focused on whether you have a compliant recording system at all than on whether your device's label is fully readable.
How to avoid it
Because this code involves device information and labeling, prevention is straightforward:
-
Before each shift, visually inspect your ELD or approved recording device. Check that the manufacturer name, model number, and any certification stickers or labels are intact and legible. If stickers are peeling, scratched, or missing, contact your fleet to have them replaced.
-
Keep your device mounted or stored where an inspector can easily see its information. Don't bury it under cables, covers, or mounting hardware that obscures the label. Inspectors need to read the device details at a glance.
-
If you're running an older approved automatic recording system (not an ELD), verify with your carrier that all required device identifiers are still displayed. Over time, labels fade or equipment moves; a quick check prevents a citation.
-
Ensure your fleet's maintenance department logs device replacements and label updates. If your ELD is swapped out or serviced, confirm that new labeling meets FMCSR requirements before you drive.
-
During a pre-trip inspection, treat your recording device like any other required equipment component. A working, clearly labeled device is part of your legal readiness, not an afterthought.
Given the minimal enforcement activity in recent years, this violation is unlikely to be your primary roadside concern. But it's a quick fix: a legible device with visible manufacturer and certification information keeps you compliant and out of an inspector's citation clipboard.
