What 395.32C1 means in plain language
FMCSR 395.32C1 prohibits you from tampering with, disabling, or otherwise interfering with your electronic logging device (ELD). Your ELD is the digital system mandated by the Federal Motor Carrier Safety Administration to record your hours of service automatically. It's designed to be tamper-resistant and to give inspectors a reliable picture of your driving and on-duty time.
Tampering can take many forms: physically disconnecting the ELD, attempting to bypass its data connection, falsifying the records it generates, or using software or hardware to manipulate its output. The regulation exists because ELD integrity is foundational to safety. When an ELD is disabled or falsified, inspectors cannot verify whether you've complied with hours-of-service rules, which are in place to prevent fatigue-related crashes.
If you're cited for this violation, it means an inspector found evidence—usually during a roadside inspection—that you had altered or disabled your device in some way.
What our enforcement data actually shows
Across our 13 million inspection records, 395.32C1 citations are rare. Our database shows 101 citations for this code in all-time enforcement history. In the last 12 months, we recorded zero citations, and in the last 90 days, zero citations as well. This code ranks #1420 out of 3,036 FMCSR codes by citation volume.
Here's what's particularly important for your case: none of the 101 citations on record resulted in an out-of-service order. The out-of-service rate for 395.32C1 is 0.0%. This is substantially lower than the all-FMCSR average out-of-service rate of 31.4%, which means inspectors typically do not remove you from service for this violation alone.
That said, a citation still carries a CSA severity weight of 10 and will appear on your FMCSA Safety Management System (SMS) profile. It affects your Violations safety event and your overall crash risk profile.
Who gets cited most
Our enforcement data does not identify state-specific citation patterns for 395.32C1 given the low citation volume. However, we can point to carriers in our database who have received multiple citations for this code. DIWAN TRANSPORT LLC (USDOT 4238329) has received 3 citations for 395.32C1. HMNG TRUCKING LLC (USDOT 2966437), FREEWAY TRUCKING INC (USDOT 2725780), NOMADS TRUCKING LLC (USDOT 3853127), and L A BOYS TRANSPORT INC (USDOT 3175871) each have 2 citations. The remaining carriers in our top-cited list have 1 citation each.
The vehicle makes most commonly cited for this violation are Freightliner (13 citations), FRHT (12 citations), Volvo (11 citations), and utility vehicles (11 citations). This likely reflects the overall distribution of trucks on roadways rather than any defect specific to those makes.
How severe is this compared to similar codes
FMCSR 395.32C1 sits in the Hours of Service category alongside several other ELD and record-of-duty-status violations. Our data reveals important contrasts:
395.24 (ELD Form and Manner) has far higher citation volume—106,486 citations in our database—but the same 0.0% out-of-service rate as 395.32C1. This suggests form/manner violations are detected more frequently but are rarely deemed severe enough for immediate removal.
395.8(a)(1) (Not using the appropriate method to record hours of service) shows a starkly different enforcement picture: 39,561 citations and a 93.2% out-of-service rate. When inspectors find you are not using a required record method at all, they remove you from service far more often than when they find tampering.
395.8A1-HOSP (Failing to have a record of duty status using the method prescribed) has 52,266 citations and a 92.9% out-of-service rate, again showing that absence of records triggers more severe action than tampering.
The comparison suggests that inspectors treat ELD tampering differently than structural failures to use any logging system. A tampered device, while a violation, may not automatically indicate hours-of-service non-compliance, whereas complete absence of records does.
How to avoid it
Prevention is straightforward and starts before you depart:
-
Know your ELD system. Read the manual for your specific device. Understand what's normal operation versus what constitutes interference. If you don't understand a feature, ask your fleet safety manager or the device vendor before you need to troubleshoot.
-
Never physically disconnect or unplug your ELD. This includes the power supply, data connector, or any intermediate cables. If your ELD appears to malfunction, pull over at a safe location and contact your dispatcher or safety department. Do not attempt hardware-level repairs yourself.
-
Do not use third-party software or unauthorized adapters claiming to "optimize" or "modify" your ELD data or function. These tools are designed to circumvent the device and will trigger citations.
-
Verify the device powers up during pre-trip inspection. Check that it displays and updates correctly as you perform your pre-trip walk-around. If it's stuck on an old timestamp or shows an offline status, report it immediately and do not operate until it's resolved.
-
Keep your ELD synchronized with your vehicle's ignition. Most modern ELDs log automatically when the engine starts. Do not restart your engine repeatedly to reset driving time, and do not disable the vehicle's power to the ELD between trips.
-
Review your ELD records before signing off each day. Inspectors check whether you've certified that your ELD data is accurate. If you spot an error—a missing stop, a time gap, an incorrect vehicle assignment—correct it through the proper ELD function rather than attempting to edit raw data.
These steps protect both your safety record and your ability to operate. The data shows that tampering citations are uncommon, which means the vast majority of drivers operate ELDs without issue. Treating your ELD as a transparent, mandatory tool—not an obstacle—keeps you compliant.
