A driver finishes a route, notices a cracked mirror mount, and isn’t sure whether that means paperwork or not. Multiply that moment across a fleet of forty trucks and you’ve got the most common compliance question in trucking: when does a DVIR actually have to be completed and signed? The answer is more specific than most fleets assume, and getting it wrong in either direction like skipping a required report or drowning drivers in unnecessary paperwork, creates real risk. This article gives you the direct FMCSA answer, who needs to sign at each step, and how long you’re required to keep the records.
When Is a DVIR Actually Required?
A Driver Vehicle Inspection Report (DVIR) is required under 49 CFR §396.11 at the end of each day a driver operates a commercial motor vehicle — but whether that report must be submitted depends on what the vehicle carries. For property-carrying CMVs (most trucks and freight trailers), a DVIR is only required to be prepared and submitted if the driver finds or is told about a defect or deficiency that affects safety or could cause a breakdown. If the vehicle has no defects, no report needs to be filed. For passenger-carrying CMVs, the rule is different: drivers must complete, sign, and submit a DVIR at the end of every day, whether or not anything is wrong with the vehicle.
That distinction, property versus passenger, is where most compliance confusion starts, and it’s worth understanding in full before setting internal policy for your fleet.
The FMCSA Rule Most Fleets Get Wrong
Many fleet managers still operate under the older assumption that every commercial vehicle needs a signed DVIR every single day, defect or not. That hasn’t been true for property-carrying vehicles since a 2014 FMCSA rule change, and the confusion has only grown since a separate 2020 rule extended similar relief to some passenger operations while leaving daily reporting in place for others. Here’s how the requirement actually breaks down.
Property-Carrying Vehicles: Required When a Defect Is Found
Drivers of property-carrying CMVs are not required to submit or sign a DVIR if they complete an inspection and find no safety defects. The inspection itself still needs to happen — the paperwork requirement is what’s been removed, not the inspection. A report becomes mandatory the moment a driver discovers or is told about a defect or deficiency in one of the parts and accessories covered by §396.11(a), such as brakes, lights, tires, or steering.
Passenger-Carrying Vehicles: Daily DVIR Rules Are Different
Passenger-carrying CMVs operating in interstate commerce did not get the same relief. Drivers of buses and other passenger vehicles must complete, sign, and submit a DVIR at the end of every operating day, even when the inspection turns up nothing. This applies regardless of whether the vehicle has been driven all day or briefly for a short route, and it’s a rule auditors check by comparing operating days against filed DVIRs.
No-Defect DVIRs: Not Always Federally Required, Still Often Used
Even though property-carrying drivers aren’t federally required to file a report when there’s no defect, plenty of fleets still require it as internal policy. There’s a practical reason for this: a daily no-defect report creates a consistent record that inspections are actually happening, not just an assumption that they are. If your company still wants daily reports regardless of the federal minimum, that’s a valid internal safety decision — just be clear with drivers about which requirement is company policy versus federal law, so nobody assumes a missed no-defect report is a DOT violation when it isn’t.
Multi-Day Trips and Multiple Vehicles
A DVIR must be prepared at the completion of each day’s work on each vehicle operated that day, not just once per multi-day trip. A driver on a three-day haul completes a report (when required) at the end of each of those three days, not one report at the end of the trip. Likewise, a driver who operates two or more vehicles within a 24-hour period must prepare a separate DVIR for each vehicle, since the report is tied to the vehicle and the day, not the driver’s overall shift.
Who Has to Sign the DVIR?
When a defect is reported, the sign-off process involves up to three people. First, the driver who conducted the inspection signs the report, noting the defect. Second, if repairs are made — or if the carrier determines no repair is necessary, a mechanic or authorized motor carrier representative signs to certify that outcome. Third, the next driver to operate that vehicle must review the previous DVIR and sign to confirm they’ve seen it and that any noted repairs were completed before driving.
That third signature is the one fleets most often lose track of, since it depends on the report physically or digitally reaching the next driver before they start their shift, not just getting filed somewhere in the office.
What Happens After a Defect Is Reported?
Once a defect is documented, the motor carrier is responsible for taking action before the vehicle goes back on the road. If the defect affects safe operation including brakes, steering, lights, and similar systems, it has to be repaired and certified before the vehicle is dispatched again. If the carrier determines the item doesn’t need repair, that determination also has to be documented and signed, not just assumed. This is the sequence most audits focus on: a defect gets reported, but the paper trail showing it was actually addressed is incomplete or missing. A driver vehicle inspection guide walks through the full pre-trip and post-trip cycle if you want the complete picture beyond just the DVIR requirement.
DVIR Requirements Before the Vehicle Goes Back on the Road
Before operating a vehicle, a driver is required to review the previous DVIR for that vehicle if one exists and was required. This isn’t a separate inspection, it’s confirmation that any defects noted the day before were either repaired or determined not to need repair, and that the driver is aware of the vehicle’s condition before taking it out. Skipping this review is a common violation precisely because it’s easy to overlook when the previous report isn’t readily available in the cab or accessible digitally before the shift starts.
What Must Be Included in a DVIR?
A DVIR must identify the vehicle, note the date, and list any defect or deficiency discovered by or reported to the driver that would affect safe operation or could cause a mechanical breakdown. At minimum, this covers service brakes and trailer brake connections, parking brake, steering mechanism, lighting devices and reflectors, tires, horn, windshield wipers, rear vision mirrors, coupling devices, wheels and rims, and emergency equipment. If no defects are found on a report that’s being filed anyway (such as a company-required no-defect report, or any passenger-carrying vehicle report), the driver certifies that the vehicle is in satisfactory condition. For a full breakdown of every item and how to structure the form itself, see the dvir checklist.
How Long Do Fleets Need to Keep DVIR Records?
DVIRs and their related repair certifications must be retained for three months from the date the report was prepared. That applies whether the report is on paper or completed electronically, the retention clock doesn’t reset based on format. Fleets that keep records digitally tend to have an easier time producing them on request, since a searchable system doesn’t depend on someone locating a specific paper form in a filing cabinet or glovebox.
Stay Ready for DVIR Audits with Whip Around
The short version: a DVIR is required whenever a property-carrying driver finds a defect, required daily for passenger-carrying drivers regardless of defects, and needs up to three signatures to close the loop once a defect is reported. Records need to be kept for three months and available when an auditor asks for them.
FMCSA has also moved to remove ambiguity around digital recordkeeping, a 2026 final rule explicitly authorized electronic DVIRs under §396.11 and §396.13, on top of the guidance that’s permitted them for years. That matters because the biggest source of DVIR violations usually isn’t a misunderstanding of the rule — it’s a process breakdown: a defect gets reported but the next driver never sees the DVIR before pulling out, or a three-month-old paper record can’t be found when it’s needed.
Whip Around’s eDVIR tools capture all three signatures digitally, timestamp each one, and keep records searchable well past the three-month retention window. For fleets in DOT compliance and electronic dvir for trucking operations specifically, that means a defect reported at 6pm doesn’t get lost before the next driver clocks in at 6am. If you want to see how it fits your fleet’s DVIR workflow, book a demo and walk through your current process.
FAQs
Is a DVIR mandatory every day?
Not for property-carrying CMV drivers. A report is only required when a defect or deficiency is found or reported. Passenger-carrying CMV drivers must complete a DVIR every day regardless of whether defects are found.
When must a driver sign a DVIR?
A driver signs the DVIR at the completion of each day’s work on each vehicle operated, whenever a report is required, either because a defect was found or because the vehicle is passenger-carrying.
Does the next driver need to review the previous DVIR?
Yes. Before operating the vehicle, the next driver must review the prior DVIR (when one was required) and sign to confirm they’ve seen it and that any needed repairs were completed.
How long should DVIR records be kept?
DVIRs and any related repair certifications must be retained for three months from the date the report was prepared, whether stored on paper or electronically.
