What 393.76(c) means in plain language
FMCSR 393.76(c) addresses the physical condition and dimensions of your sleeper berth. The regulation requires that any sleeper berth installed on a commercial motor vehicle meet specific equipment standards and dimensional requirements set by federal safety rules.
In practical terms, this means your sleeper compartment must be properly constructed, securely installed, and meet minimum size requirements. The inspection officer is checking whether the sleeper berth itself—not your driving fitness or the overall truck condition—complies with federal design specifications. If the bunk is damaged, improperly mounted, too small, or missing required components, you can be cited under this code.
This is a vehicle maintenance violation tied directly to the sleeper equipment itself, separate from other inspection failures like brake or lighting defects.
What our enforcement data actually shows
Across our 13 million+ inspection records, 393.76(c) citations are extremely rare. Our database shows only 4 all-time citations for this violation, with zero citations in the last 12 months and zero in the last 90 days. This code ranks #2480 of 3,036 FMCSR codes by citation volume.
Moreover, this citation carries a 0.0% out-of-service rate—meaning none of the 4 citations resulted in an out-of-service order. For context, the all-FMCSR average out-of-service rate is 31.4%, so 393.76(c) is enforced far less frequently than typical vehicle maintenance violations and has never led to an immediate roadside removal.
If you've been cited for this, you're in a small statistical minority. The violation exists on the books but is seldom encountered in actual roadside enforcement.
Who gets cited most
Our inspection records do not include state distribution data for this code due to its low citation volume. However, the top carriers cited for 393.76(c) in our all-time database are NATION WIDE DELIVERY LLC (USDOT 2817889), LEMON TREE INC (USDOT 4000427), FLAT LINE SERVICES LLC (USDOT 4050972), and THACKER & SONS INC (USDOT 4180349)—each with 1 citation. The vehicles involved included Ford units (2 citations) and individual citations on BIG TEX, DODGE, HINO, KAUFMAN, and other makes.
The extremely limited citation history means carrier or geographic patterns are not statistically meaningful.
How severe is this compared to similar codes
Within vehicle maintenance, 393.76(c) is less commonly cited than several peer codes. For example, 393.9(a) for inoperable required lamps has generated 660,737 citations with a 15.4% out-of-service rate. The general maintenance code 396.3(a)(1) has 236,919 citations with a 45.3% out-of-service rate. Even 393.78 for windshield condition defects—also a visual equipment issue—has 157,894 citations, far exceeding 393.76(c).
The rarity of 393.76(c) enforcement suggests inspectors rarely encounter sleeper berths that fail to meet dimensional or equipment standards, or the condition is often corrected before a citation is issued.
How to avoid it
Because sleeper berth citations are rare in our data, target prevention toward general sleeper inspection and maintenance:
- Pre-trip walk-around: Check that your sleeper bunk is securely fastened to the truck frame, with no visible movement or separation at mounting points. Look for cracks, warping, or broken structural elements.
- Measure your bunk: Verify that your sleeper meets the minimum length, width, and headroom specifications required by federal standards. If you're unfamiliar with the exact dimensions, consult your truck's manufacturer documentation or fleet specifications.
- Inspect mounting hardware: Ensure all bolts, welds, and attachment points are intact. Loose or corroded fasteners can compromise the structural integrity of the sleeper.
- Check for damage: If your sleeper has been in any collision, accident, or impact, have it inspected and certified as compliant before returning to the road.
- Know your vehicle: Drivers of Ford, DODGE, HINO, or other makes with sleeper configurations should be especially attentive to sleeper condition during routine maintenance intervals.
Because this violation is not out-of-service eligible, a citation won't sideline you at the roadside, but you will be required to correct the defect before your next inspection or operation cycle.
