DOT Compliance for Small Fleets: The Complete Checklist
DOT compliance is not one rule — it is roughly a dozen recurring obligations that a one-truck authority and a twenty-truck carrier both have to keep current. Here is every piece, what it costs, how often it comes due, and what happens when it lapses.
What does DOT compliance require for a small carrier?
A DOT-compliant carrier keeps an FMCSA-registered ELD with current HOS logs, driver qualification files, a random drug and alcohol testing program, daily DVIRs and annual inspections, IFTA fuel-tax filings, UCR registration, a biennial MCS-150 update, and required insurance filings on file at all times.

The recurring obligations
Most new-authority carriers fail an audit on paperwork, not on driving. These are the items that come due on a schedule and that an auditor will ask for by name.
- ELD and HOS records: current day plus 7 prior days in the truck; 6 months retained by the carrier
- Driver qualification file per driver: application, MVR annually, road test, medical certificate, previous-employer checks
- Drug and alcohol program: pre-employment test, random pool enrollment, and a designated employer representative
- DVIRs: driver vehicle inspection reports for any defect, plus an annual DOT inspection per power unit
- IFTA: quarterly fuel-tax return in your base state if you cross state lines over 26,000 lbs
- UCR: annual Unified Carrier Registration, due by December 31 for the following year
- MCS-150: biennial update based on your USDOT number, even if nothing changed
- Insurance: BMC-91X on file with FMCSA at the required liability level
What triggers an audit
Every new authority gets a New Entrant Safety Audit within the first 12 months. After that, audits are driven by your CSA scores, a crash, a complaint, or an out-of-service pattern found at roadside. The single most common trigger for an established carrier is a BASIC score crossing an intervention threshold — and Hours of Service is the BASIC most small fleets fail.
The seven CSA BASICs
The Compliance, Safety, Accountability program scores carriers in seven categories from roadside inspection and crash data over a 24-month window. Scores are weighted by severity and recency, so a violation from last month hurts far more than the same violation two years ago.
- Unsafe Driving — speeding, reckless, seat belt
- Hours of Service Compliance — form and manner, false logs, exceeding limits
- Driver Fitness — CDL and medical card problems
- Controlled Substances and Alcohol
- Vehicle Maintenance — lights, brakes, tires, the top out-of-service category
- Hazardous Materials Compliance
- Crash Indicator
Where an ELD does the compliance work for you
An ELD is the only compliance item that runs continuously without anyone remembering to do it. It captures HOS automatically, files DVIRs from the driver app, and accumulates the state-by-state mileage that IFTA returns require. When a provider bundles those together, three of the recurring obligations largely take care of themselves.
- Automatic HOS records with an audit trail on every edit
- Electronic DVIRs with defect history per unit
- IFTA mileage by jurisdiction, generated from the same GPS data
- Roadside data transfer in the FMCSA-required format
- Six months of retained records available for an audit request
A realistic first-year compliance budget
For a single-truck authority, the compliance line items — ELD software and hardware, drug consortium, UCR, IFTA decals, and the BOC-3 filing — typically land in the low four figures for year one, with the ELD being the only recurring monthly cost. Choosing a $15 per truck per month ELD instead of a $40 contract saves roughly $300 per truck per year on that line alone.
Compliance calendar
| Item | Frequency | Who enforces |
|---|---|---|
| ELD / HOS logs | Continuous; 6-month retention | FMCSA / roadside |
| DVIR | Daily when a defect exists | FMCSA / roadside |
| Annual vehicle inspection | Every 12 months per unit | FMCSA |
| MVR review | Annually per driver | FMCSA |
| Medical certificate | Per exam expiration (max 24 months) | FMCSA / state CDL |
| Random drug testing | Ongoing pool; rates set annually | FMCSA |
| IFTA return | Quarterly | Base-state DOR |
| UCR | Annually by December 31 | UCR board |
| MCS-150 update | Every 24 months | FMCSA |

Frequently asked questions
What is DOT compliance?
DOT compliance means meeting the Federal Motor Carrier Safety Regulations that apply to your operation: Hours of Service and ELD use, driver qualification files, drug and alcohol testing, vehicle inspection and maintenance records, fuel-tax reporting, registration filings, and insurance. Carriers must be able to produce the records on demand.
What does a New Entrant Safety Audit check?
It checks whether you have the required programs in place, not whether you are perfect. Auditors look for driver qualification files, a drug and alcohol testing program, HOS records, vehicle maintenance and inspection records, insurance, and accident registers. Missing an entire program is an automatic failure.
How long do I keep DOT records?
Hours of Service records and supporting documents: 6 months. DVIRs: 3 months. Annual inspection reports: 14 months. Driver qualification files: for employment plus 3 years. Drug and alcohol testing records: 1 to 5 years depending on the record type.
Do I need an ELD if I only run one truck?
Yes, if you operate in interstate commerce over 10,001 lbs and are required to keep records of duty status. The mandate has no fleet-size floor. ELD Hub is built for exactly this case at $15 per month for one truck with no contract.
What is the most common DOT violation?
Vehicle maintenance items — lights, brakes, and tires — produce the most roadside violations and out-of-service orders, followed by Hours of Service form-and-manner errors. Both are largely preventable with consistent DVIRs and an ELD that logs automatically.
Can one platform cover all of this?
Not all of it. An ELD platform covers HOS, DVIRs, IFTA mileage, and inspection-ready record retention. Drug testing consortium, UCR, and MCS-150 filings are separate. ELD Hub covers the ELD side at $15 per truck per month and links members to factoring, fuel, insurance, and capital partners for the rest.
