# Ohio Trucking Compliance: When the Utilities Commission Is Your Safety Regulator Canonical page: https://fleetregulators.com/locations/ohio Page type: Location guide | Published: 2026-11-07 | Last updated: 2026-11-07 Summary: Ohio trucking rules: PUCO inspections, reviews and certificates, the fixed federal adoption date, intrastate exceptions and Ohio inspection data. --- Ohio adopts the federal motor carrier safety regulations (including 49 CFR Parts 382, 383, 385 and 390 to 397) for both interstate and intrastate carriers, as they were in effect on **August 1, 2025**, unless the Public Utilities Commission of Ohio (PUCO) excludes or modifies them (Ohio Administrative Code 4901:2-5-02 and -03). PUCO's Motor Carrier Division oversees commercial vehicle safety: its inspectors conduct roadside inspections and compliance reviews, PUCO assesses the fines, and PUCO issues the certificate (CPCN) every for-hire intrastate carrier must hold before operating. Intrastate drivers may be 18 (21 for placardable hazmat without the proper endorsement), and Ohio's 12-hour driving and 16-hour duty limits apply only to intrastate construction materials and equipment haulers.

Sources ## Who this guide is for Ohio is home to 26,377 interstate carriers in FMCSA's census (seventh of 51), 84.0% of them running 10 or fewer power units. This guide is for Ohio carriers working out what PUCO expects, and for safety managers comparing Ohio's rules with the federal baseline. Carriers in central Ohio can also see our [Columbus metro page](https://fleetregulators.com/locations/columbus-oh). 26,377 Ohio-based interstate carriers (7th of 51) 126,569 Inspections reported by Ohio in 24 months 7.5% Ohio driver inspections with an HOS violation ## Where Ohio's rules differ from federal rules | Topic | Federal (interstate) | Ohio intrastate | | --- | --- | --- | | Federal rule version | Current CFR | CFR as in effect on August 1, 2025 (fixed date) | | Hours of service | 11 driving / 14-hour window | Federal limits, except intrastate construction materials and equipment hauling to or from an active site within 50 air miles (no placarded hazmat): 12 hours driving after 10 off, no driving after 16 hours on duty, 70/7 or 80/8 | | Minimum driver age | 21 | 18; 21 for placardable hazmat unless the driver holds the proper endorsement | | Medical qualification | 49 CFR 391.41 | Grandfathered provisional certification for drivers in CMV jobs on or before December 7, 1988; no new or renewed provisional certificates for insulin-treated diabetes since July 1, 2021 | | Employment application and inquiries | 391.21 and 391.23 | Exempt for single-employer drivers continuously employed since before January 1, 1987 | | Vehicle marking | USDOT number | A PUCO number may replace the USDOT number; private intrastate carriers need not display either | ## What the fixed federal adoption date means The fixed adoption date cuts both ways: a federal change made after August 1, 2025 does not apply to Ohio carriers through the state rule until PUCO updates the date, while interstate carriers are bound by the current federal text directly. Ohio also defines its planting and harvesting season as the whole year for the federal agricultural hours exemption (OAC 4901:2-5-15), and requires wheel protectors (mud flaps) on motor carrier vehicles whose loaded gross weight exceeds three tons (OAC 4901:2-5-08). The provisional medical certificate never qualifies a driver for interstate driving. ## PUCO: inspector, auditor, fine-setter and licensing agency PUCO's Transportation Department, Motor Carrier Division, oversees commercial motor vehicle safety for carriers operating in Ohio. PUCO and the Ohio State Highway Patrol both work on commercial vehicle safety, and PUCO inspectors conduct roadside inspections. PUCO inspectors also carry out on-site compliance reviews of interstate and intrastate carriers and issue safety ratings, and PUCO compliance officers conduct new entrant safety audits for Ohio-based carriers. One consequence surprises carriers from other states: civil forfeitures for safety violations found at roadside inspections or compliance reviews are assessed by PUCO, not by local courts. The same agency also handles intrastate registration, so a PUCO compliance problem and a PUCO authority problem can show up together. ## PUCO certificates, USDOT numbers and UCR For-hire intrastate carriers must register with PUCO and hold a valid PUCO certificate (a CPCN) before operating in Ohio (OAC 4901:2-21-03). PUCO does not issue a CPCN to private carriers hauling their own property. The certificate is renewed every year between May 1 and June 30 through PUCO's online system, and intrastate for-hire carriers must have their insurer file proof of insurance with PUCO (Form E; Forms E and H for household goods movers). For-hire carriers that participate in [UCR](https://fleetregulators.com/blog/what-is-ucr-registration) still need the initial CPCN but do not renew it annually, except household goods carriers. Hazmat carriers register with PUCO only if they operate intrastate, and intrastate household goods movers have their own rules (OAC 4901:2-19). On USDOT numbers, PUCO says carriers operating vehicles of 10,001 pounds GVWR/GCWR or more need one even if no CDL is required, and FMCSA lists Ohio among the states that require intrastate registrants to obtain one. For intrastate operations, Ohio's rules apply to for-hire carriers from 10,001 pounds (the 49 CFR 390.5 definition) but to private carriers only for vehicles that meet the CDL-class definition in 49 CFR 383.5: generally 26,001 pounds or more, 16 or more passengers, or placarded hazmat (OAC 4901:2-5-01). Private intrastate carriers are exempt from displaying a USDOT or PUCO number. ## What Ohio roadside inspections find Ohio's inspection profile sits close to the national pattern, with one tilt toward lighting: brakes are the most frequent violation group, followed closely by lighting, then clearance and identification lamps and tires. The driver out-of-service rate at Ohio inspections was 5.9% (national 6.2%) and the vehicle rate 22.2% (national 22.5%). | Roadside inspections, September 25, 2024 to September 24, 2026 | Ohio | 50 states and DC | | --- | --- | --- | | Inspections reported by the state (all carriers) | 126,569 | 5,653,653 | | Driver out-of-service rate | 5.9% | 6.2% | | Vehicle out-of-service rate | 22.2% | 22.5% | | Driver inspections with at least one HOS violation | 7.5% | 7.8% | | Vehicle inspections with at least one maintenance violation | 48.1% | 48.9% | | Most frequent violation groups at Ohio inspections | Violations | Share of all violations recorded | | --- | --- | --- | | Brakes, other than adjustment (FMCSA: Brakes All Others) | 18,450 | 17.0% | | Lighting | 15,435 | 14.2% | | Clearance and identification lamps (FMCSA: Clearance Identification Lamps/Other) | 8,607 | 7.9% | | Tires | 7,419 | 6.8% | | Windshield, glass and markings (FMCSA: Windshield/ Glass/ Markings) | 5,489 | 5.1% | Source: Fleet Regulators analysis of FMCSA Safety Measurement System (SMS) input files, monthly run published October 2026, covering roadside inspections recorded September 25, 2024 to September 24, 2026. "In the state" means the inspection was reported by Ohio, whatever the carrier's home state. Driver rates use Level 1, 2, 3 and 6 inspections; vehicle rates use Level 1, 2, 5 and 6. Group names are FMCSA's. Same method as our [HOS roadside violations study](https://fleetregulators.com/research/most-common-hos-roadside-violations). 67.6% of the inspections Ohio reported in this window involved carriers based in another state, and 32.4% involved Ohio-based carriers, so these figures describe through-traffic as much as Ohio fleets. Ohio-based interstate carriers, wherever inspected, had a driver out-of-service rate of 5.1% and a vehicle out-of-service rate of 20.9%. These figures describe what inspectors recorded, not how safe carriers in the state are. Rates move with enforcement priorities, which inspection levels a state favors, where it inspects, and which carriers pass through. ## Ohio compliance checklist - For-hire intrastate: hold a PUCO CPCN before operating, keep a Form E on file, and renew May 1 to June 30 (unless UCR covers renewal). - Get a USDOT number for vehicles of 10,001 lb or more, as PUCO advises; private intrastate carriers do not have to display it. - Apply 12/16 hours only to intrastate construction materials and equipment hauling. - Track drivers aged 18 to 20 and drivers with provisional medical certificates; keep them on intrastate, non-placarded loads. - Keep driver qualification files (see the [DQ file checklist](https://fleetregulators.com/blog/driver-qualification-file-checklist)) and [Clearinghouse](https://fleetregulators.com/blog/what-is-fmcsa-clearinghouse-and-how-does-it-work) records ready for a PUCO compliance review. - Check brakes, lamps and mud flaps on pre-trips; document annual inspections. - After each PUCO rulemaking, check whether the federal adoption date has moved. ## How Fleet Regulators supports Ohio carriers We work with Ohio carriers remotely from Austin, Texas; we have no Ohio office. For Ohio fleets that means preparing for a PUCO [compliance review](https://fleetregulators.com/dot-audit-help) or [new entrant audit](https://fleetregulators.com/new-entrant-audit-help), building [driver qualification files](https://fleetregulators.com/driver-qualification-files), auditing logs ([HOS log auditing](https://fleetregulators.com/hours-of-service-compliance)), and responding to roadside findings before they turn into forfeitures or higher [CSA scores](https://fleetregulators.com/csa-score-improvement). ## Frequently Asked Questions **Who enforces trucking safety rules in Ohio?** The Public Utilities Commission of Ohio's Motor Carrier Division oversees commercial vehicle safety. PUCO inspectors conduct roadside inspections, compliance reviews and new entrant audits, and PUCO assesses civil forfeitures. The Ohio State Highway Patrol also works on commercial vehicle safety. **Do Ohio intrastate carriers need a PUCO certificate?** For-hire intrastate carriers must register with PUCO and hold a valid certificate (CPCN) before operating. PUCO does not issue a CPCN to private carriers hauling their own property. **Which version of the federal rules does Ohio follow?** Ohio incorporates the federal motor carrier safety regulations as they were in effect on August 1, 2025, unless PUCO excludes or modifies a provision. Interstate carriers are also bound by the current federal text directly. **Can an 18-year-old drive a truck intrastate in Ohio?** Yes. Ohio sets the intrastate minimum age at 18, or 21 for placardable hazmat unless the driver holds the proper hazmat endorsement. Interstate driving requires age 21. **Can Ohio intrastate drivers drive 12 hours?** Only intrastate drivers hauling construction materials and equipment to or from an active construction site within 50 air miles of their work reporting location, who may drive 12 hours after 10 consecutive hours off and not after 16 hours on duty. Other Ohio drivers follow federal Part 395. **When is the Ohio intrastate certificate renewed?** Annually, between May 1 and June 30, through PUCO's online system. Carriers participating in UCR do not renew annually, except household goods carriers. Sources and Regulatory References - [Ohio Adm.
