What 390.19TA means in plain language
390.19TA relates to periodic inspection requirements for commercial motor vehicles. The regulation establishes when and how often your vehicle must be inspected to confirm it meets federal safety standards. These inspections are meant to catch mechanical or structural problems before they become safety hazards on the road.
If you've been cited for 390.19TA, it typically means an inspector found a deficiency in how your vehicle's periodic inspection was conducted, documented, or maintained. This could include missing inspection records, an inspection that wasn't performed at the required interval, or documentation that didn't meet federal standards. The citation flags a paperwork or procedural gap rather than a specific mechanical failure.
What our enforcement data actually shows
Across our 13 million roadside inspection records, 390.19TA has generated 1,194 all-time citations, with 771 citations issued in the last 12 months and 176 in the last 90 days. This ranks the code #669 out of 3,036 FMCSR codes by citation volume—a middle-of-the-pack enforcement level.
What matters most for your situation: the out-of-service rate for 390.19TA is 0.0%. In every single case in our database, inspectors did not place the vehicle out of service. This contrasts sharply with the all-FMCSR average out-of-service rate of 31.4%. You won't be stranded at the roadside because of this citation.
The enforcement pattern shows steady activity. May 2025 had the highest monthly count at 86 citations, followed by March 2026 with 89 citations. Most other months ranged from 54 to 82 citations. This consistency suggests the violation is routinely caught but isn't treated as an emergency-level safety issue.
Who gets cited most
Our data for the last 180 days shows Florida leading with 60 citations, followed by California with 57, and Virginia with 41. All three states maintained a 0.0% out-of-service rate, matching the national pattern—none of these citations resulted in roadside vehicle removal.
Among carriers in our all-time records, TEEN CHALLENGE OF FLORIDA (USDOT 3213785) appears most frequently with 5 citations, followed by RANDOLPH POWELL (USDOT 2951350), BURCHETTE SIGN COMPANY (USDOT 3145222), MIDWEST SEALCOAT LLC (USDOT 1157915), and TAMPA TRUCKS LLC (USDOT 3247759), each with 4 citations. The low citation counts per carrier suggest 390.19TA violations are spread widely across the trucking industry rather than concentrated in a few problem fleets.
By vehicle make, Ford leads with 179 citations across all records, followed by Freightliner with 117 and International with 81 citations. These manufacturers dominate trucking generally, so their higher numbers reflect market share rather than a pattern of defective vehicles.
How severe is this compared to similar codes
390.19TA sits in the General/Admin category alongside several related inspection codes. For comparison:
- 390.21TB2-DOT has logged 74,663 citations with a 0.0% OOS rate—far more enforcement volume but identical safety outcome.
- 390.21TB1-MC shows 59,189 citations at 0.0% OOS rate—again, higher enforcement but no roadside removals.
- 390.21T(b) accounts for 61,097 citations, also at 0.0% OOS rate.
These peer codes share the same out-of-service pattern: high citation counts but zero vehicles pulled. This tells you that violations in this family of administrative and marking requirements are treated as correctable paperwork issues, not immediate safety threats.
How to avoid it
Our inspection data reveals which violations commonly appear alongside 390.19TA in the same roadside check. The patterns point to clear prevention steps:
-
Maintain a current periodic inspection record in the vehicle. The inspection most frequently co-occurring with 390.19TA is 396.17C-PI (No proof of periodic inspection), appearing in 47 shared inspections over the last 90 days. Before you depart, confirm your inspection documentation is complete, legible, and accessible in the cab.
-
Perform a thorough pre-trip inspection yourself. Operations cited for 392.2-SLLUCR (Operating a CMV while ill or fatigued) co-occur in 46 inspections, and 392.2-SLLSR in 43. A disciplined walk-around—checking lights, tires, brakes, coupling devices, and emergency equipment—catches problems before an official inspection becomes necessary and also ensures you're alert and fit to drive.
-
Verify medical certificate status. 391.41APC (Medical Certificate violations) co-occur in 39 inspections. Confirm your medical certificate is valid and on file with your state's licensing agency before road hours begin.
-
Check emergency equipment. 393.95A1 (missing or improperly rated fire extinguishers) co-occurs in 28 inspections, and 393.95F (warning devices missing or improper) in 26. These items are quick to verify and critical to carry.
-
Review your carrier's inspection interval schedule. Work with your fleet to confirm when the last periodic inspection was completed and when the next one is due. Missing or delayed inspections are the root cause of most 390.19TA citations.
The good news: because 390.19TA carries zero out-of-service risk in our data, your citation is fixable. Complete the inspection that triggered the citation, document it properly, and keep that record with you. No vehicle impound, no emergency repair—just a paperwork correction.
