Fleet Regulators supports Indianapolis-area trucking companies remotely from Austin with HOS and ELD log auditing, driver qualification files, driver coaching, drug and alcohol records and DOT audit preparation. We have no Indianapolis office. Indiana adopts the federal safety rules for both interstate and intrastate carriers, with Indiana exceptions; the Indiana State Police Commercial Vehicle Enforcement Division enforces them, and the Department of State Revenue handles intrastate credentials. Indiana requires a USDOT number for commercial vehicles from 10,001 pounds in intrastate as well as interstate commerce, with exemptions. And Indiana's inspection data stands out for driver findings: speeding is the most frequent violation group, and 19.9% of driver inspections recorded an HOS violation.

Who this page is for

Indiana is home to 18,630 interstate carriers and 26,375 intrastate carriers in FMCSA's census. This page is for Indianapolis-area carriers such as:

  • Regional and over-the-road fleets using the I-65, I-69 and I-70 corridors.
  • Distribution and logistics fleets serving the metro's warehouse clusters.
  • Private carriers and construction fleets operating only within Indiana.
  • Small fleets where nobody is assigned to safety full time.

Freight volume, congestion and truck parking

INDOT reports that 724 million tons of freight travel through Indiana each year, making it the fifth busiest state for commercial freight traffic. Its 2018 state freight plan notes significant recurring peak-hour congestion on I-465, I-65 and I-70 in and around Indianapolis, and its 2023 Rest Area and Truck Parking Plan found that commercial truck crashes were greatest in northwest Indiana and around the Indianapolis metropolitan area (2016 to 2019 data). The same plan proposes converting nine existing rest areas to truck-parking-only facilities, mostly around Indianapolis, because those sites hit capacity during peak overnight hours.

What Indiana inspections find

Speeding is the most frequent violation group at Indiana inspections, followed by log form-and-manner violations, brakes and miscellaneous violations. 19.9% of Indiana driver inspections recorded an HOS violation, against 7.8% nationally. 78.3% of the inspections Indiana reported in this window involved carriers based in another state, and 21.7% involved Indiana-based carriers, so the numbers describe interstate through-traffic as much as Indiana fleets.

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 Indiana, 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.

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. For an Indianapolis fleet, the practical message is that speed and logs are where Indiana enforcement looks. Speeding violations carry heavy weights in the Unsafe Driving BASIC; see our CSA scores explainer.

Indiana rules for Indianapolis fleets

Indiana incorporates federal Parts 40, 375, 380, 382 to 387, 390 to 393 and 395 to 398 by reference for both interstate and intrastate carriers, subject to listed exceptions (IC 8-2.1-24-18). The main Indiana-specific points:

  • Private intrastate threshold: the general adoption does not apply to private intrastate carriers whose vehicles are 26,000 pounds or less, unless for-hire, carrying 16 or more passengers, or placarded hazmat. Federal hazmat rules still apply to them.
  • Driver age: drivers aged 18 to 20 may drive intrastate, and remain subject to the rest of Part 391.
  • Hours exceptions: Part 395 does not apply to drivers of BMV-registered farm trucks, intrastate construction vehicles, or vehicles restoring utility service after an emergency.
  • Insulin waiver: insulin-treated drivers of private intrastate carriers or intrastate construction carriers may drive under a BMV intrastate medical waiver; it is not available to every intrastate driver.
  • USDOT and DOR credentials: Indiana DOR says a USDOT number is needed for commercial vehicles (10,001 pounds or more, or listed passenger thresholds) in interstate or intrastate commerce, with exemptions for farm-plated in-state vehicles and private non-hazmat in-state carriers under 26,000 pounds. For-hire intrastate carriers with vehicles under 10,000 pounds get an Indiana ID number instead. Intrastate property carriers may not operate until DOR acknowledges their filing, and that acknowledgment expires December 31 of the year issued. Intrastate for-hire carriers and hazmat haulers need a Form E insurance filing with DOR.

What Indianapolis carriers get

There is no Indianapolis office to visit, and the work does not need one: you share read-only ELD access and documents through a secure folder, and we review, fix and report on a set schedule. For Indiana fleets we review speed data and logs together, because speeding and HOS problems usually share a cause.

Client results reported on our Results page, with each client's context: SBS Trucking Services' Vehicle Maintenance BASIC moved from 93% to 65% in six months; Sandhu Trucking Services' HOS BASIC moved from 85% to 71% over five months; and Tamana Truck Lines' monthly HOS violations were reduced to near zero for extended periods. These are client-reported results, not guarantees.
