What 392.16B-DPASS means in plain language
This regulation applies to any commercial motor vehicle driver whose truck or van has a seat belt assembly installed at the driver's seat. The rule is straightforward: if the belt is there, you must be wearing it and properly fastened while the vehicle is in motion. There is no exception for short hauls, city routes, or low-speed operation.
The key word is "properly." Tucking the shoulder strap behind your back, sitting on the lap belt, or clipping the buckle without actually wearing the restraint all qualify as violations of this requirement. Officers can and do make this call during roadside inspections.
Under 49 CFR, the obligation falls on the driver personally. Even if your fleet manager never reminded you or the truck was borrowed, the citation lands on your record and feeds directly into your CSA profile.
What our enforcement data actually shows
Across our inspection records, 392.16B-DPASS has accumulated 4,569 all-time citations, ranking it #358 out of 3,036 FMCSR codes by citation volume — placing it solidly in the top 12% of all cited codes. That is not a rarely-enforced rule; officers are actively writing it up.
The out-of-service rate for this code is 0.0% across all 4,569 citations in our database. To put that in context, the all-FMCSR average OOS rate is 31.4%. A seat belt violation will not park your truck on the spot, but it carries a CSA severity weight of 3, which means it accumulates points in the Unsafe Driving BASIC and affects your safety score for 24 months.
Enforcement has accelerated sharply in the past year. Our inspection records show 2,797 citations in the last 12 months alone — meaning more than 61% of all historical citations for this code were issued within the past year. In just the last 90 days, 411 citations were recorded. Looking at the monthly trend, volume peaked at 368 citations in July 2025 and has remained consistently elevated, with 199 citations recorded in March 2026. This is not a trend that is cooling off.
Who gets cited most
The data in our database shows that enforcement is concentrated in specific states. Over the last 180 days, Georgia leads the country with 173 citations, followed by Massachusetts at 116 and Pennsylvania at 82. Colorado (81 citations) and New York (79 citations) round out the top five active states. If you run lanes through any of these states, treat every cab entry as a mandatory buckle-up moment — officers in these states are clearly prioritizing this check.
OOS-rate variation across these states is not a factor here — every state in the top ten shows a 0.0% OOS rate, consistent with the national picture. The citation won't take you off the road, but it will follow your record.
Our data shows fleets such as PIECE OF CAKE MOVING + STORAGE LLC (USDOT 3066988) with 11 citations and MARYLAND TREE EXPERTS (USDOT 3304931) with 11 citations appearing at the top of the carrier list by all-time count. Fleet safety managers should note that the citation history at the carrier level is visible to FMCSA and can affect SMS scores across the entire operation.
How severe is this compared to similar codes
Within the Unsafe Driving category, 392.16B-DPASS sits in a very different tier than the high-volume codes. Consider 392.2 (Operating a CMV while ill or fatigued), which has 1,208,164 citations in our database — roughly 264 times the volume of 392.16B-DPASS — and carries a 0.8% OOS rate. Or 392.2-SLLSR, with 191,232 citations and a 0.1% OOS rate. These codes generate far more inspections but have similarly low OOS rates, reinforcing that Unsafe Driving citations generally keep you moving while still hitting your CSA score.
One peer code worth noting is 392.2-SLLEQP, which carries a 2.4% OOS rate on 72,352 citations — the highest OOS rate among the peer codes in this category. That comparison highlights that 392.16B-DPASS, at 0.0% OOS, is on the least disruptive end of the severity spectrum for Unsafe Driving violations. The CSA weight of 3 is real, but you will finish your run.
How to avoid it
The co-occurrence data from our last 90 days of inspections tells a story about what else is going wrong when this citation is written. Here is what to act on before and during every trip:
-
Buckle up the moment you enter the cab. With 411 citations in just 90 days, officers are checking. Make it a pre-trip habit identical to checking mirrors — done before the engine starts, not after you pull out of the yard.
-
Check your periodic inspection documentation. No proof of periodic inspection (396.17C-PI) appeared in 79 shared inspections alongside this citation. If an officer finds a seat belt violation, they are looking at everything else too. Have your inspection paperwork current and accessible.
-
Carry your medical certificate. Our data shows 391.41APC co-occurring in 69 shared inspections. An officer who stops you for a seat belt violation may escalate to a full Level 1 inspection. A missing or expired medical certificate compounds a manageable situation into a much more serious one.
-
Verify your emergency equipment before departure. Fire extinguisher violations (393.95A1) appeared in 27 shared inspections. Walk the cab and check that your extinguisher is present, properly mounted, and rated correctly — this takes under 60 seconds on a pre-trip.
-
Inspect your lighting. Inoperable required lamps (393.9A-LIL) also showed up in 27 shared inspections. A burned-out marker or headlamp gives an officer a reason to pull you over; the seat belt check comes next.
-
Ford and Freightliner operators, pay extra attention. Our inspection records show Ford vehicles cited 633 times and Freightliner vehicles 614 times under this code — the two most-cited makes by a wide margin. If you operate either platform, the enforcement exposure is statistically higher. Check the belt hardware for wear, fraying, or a buckle that clicks but doesn't hold securely.
