What 392.2-FTSS means in plain language
392.2-FTSS addresses a fundamental requirement for all commercial motor vehicle operators: you must obey traffic control devices—signs, signals, and road markings—while driving. This includes stop signs, red lights, yield signs, lane markings, speed limit postings, and any other official traffic control device placed by highway authorities.
The violation is straightforward: if an inspector or officer observes you disregarding a traffic control device while operating a CMV, you can be cited. This might mean rolling through a stop sign, running a red light, ignoring a yield sign, or crossing a solid line where prohibited. The regulation applies regardless of road conditions, time of day, or traffic volume.
For drivers, this is one of the most basic safety rules on the road. Unlike some FMCSR violations that involve mechanical failure or logbook errors, a 392.2-FTSS citation comes down to your decision-making in the moment. Roadside inspectors and law enforcement can issue this citation if they witness the infraction themselves.
What our enforcement data actually shows
Our inspection records show a striking pattern for 392.2-FTSS: across our 13 million+ inspection database, we have recorded zero citations for this code in the last 12 months, zero in the last 90 days, and zero all-time.
With zero citations documented, there is no out-of-service rate to calculate—the OOS rate for 392.2-FTSS stands at 0.0% in our records. This does not mean the violation never occurs; rather, it suggests that when traffic control device violations do happen, they are either cited under different code variants, handled outside the formal FMCSR inspection system, or not appearing in our roadside inspection database at all.
The absence of data for this specific code variant makes it difficult to compare its severity to the overall FMCSR enforcement landscape. However, the fact that it is OOS-eligible means that if you were cited under this code, an inspector could potentially place your vehicle out of service pending correction or investigation.
Who gets cited most
Because our database shows zero citations for 392.2-FTSS in our recorded inspection data, we cannot identify states with the highest citation counts or carriers with the most citations under this specific code. This lack of recorded enforcement suggests that violations of traffic control devices may be handled through different citation codes, local law enforcement channels, or inspection processes not captured in the standard roadside FMCSR inspection database.
If you have been cited for 392.2-FTSS, you may be among a very small population flagged under this particular code designation. Contact your carrier's safety department or a transportation attorney to understand the specific circumstances of your citation and local enforcement patterns.
How severe is this compared to similar codes
Within the Unsafe Driving category, 392.2-FTSS sits alongside several related codes, though those codes focus on driver condition rather than traffic control compliance. For example, 392.2 (Operating a CMV while ill or fatigued) has generated 1,208,164 citations all-time with a 0.8% out-of-service rate. Code 392.2-SLLEWA1 (also related to operating while fatigued) shows 69,565 citations with a 1.0% OOS rate. Code 392.2-SLLS2 (Speeding 6–10 mph over limit) recorded 72,337 citations with a 0.0% out-of-service rate.
The contrast is instructive: while traffic control violations may occur less frequently in our recorded enforcement database, fatigue-related and speeding violations generate massive citation volumes. This suggests that the most common unsafe driving citations focus on driver condition and speed management rather than traffic control device obedience.
How to avoid it
Because 392.2-FTSS is about obeying traffic control devices, prevention strategies center on awareness, compliance, and deliberate decision-making:
-
Pre-trip: Route familiarization. Before driving, study your route using GPS or mapping tools. Identify construction zones, school zones, and major intersections where you will encounter controlled signals and signs. Know where you expect to encounter traffic signals, speed reductions, and lane restrictions.
-
On the road: Full attention to signage. Keep your eyes on the road ahead and anticipate traffic control devices at intersections and along highways. Do not rely solely on traffic flow; if a sign or signal is present, obey it—even if other vehicles appear to disregard it.
-
At signals and stops: Complete stops. Come to a full stop at stop signs and red lights. Roll-throughs, even partial ones, constitute a violation. Count to two before proceeding once a light turns green or the stop is clear.
-
Respect lane markings. Solid yellow and white lines are not suggestions. Do not cross solid lines except where explicitly permitted (such as in left-turn pockets). Understand that your large vehicle may require wider turning radiuses, but this does not exempt you from lane discipline.
-
Speed limit compliance. Obey posted speed limits and reduce speed in designated zones (school zones, construction zones, residential areas). Fatigue and inattention often coincide with speeding; staying alert and compliant with speed signs reduces citation risk and crash risk together.
-
Night and adverse conditions. Traffic control devices are harder to see in darkness and poor weather. Reduce speed, increase following distance, and scan the road ahead more frequently during these conditions to catch signs and signals in time.
-
CMV-specific awareness. Your commercial motor vehicle is larger and more visible to law enforcement. Inspectors and officers watch for safety violations on CMVs more closely than passenger vehicles. One traffic control violation can trigger a full Level I or Level II roadside inspection, which may uncover additional citations.
