Telematics and dashcams in commercial auto insurance

Telematics devices and dashcams record how a fleet's vehicles are driven, and insurers use that data in two places: underwriting, where a documented monitoring program can support better terms, and claims, where video can show what really happened. The research on safety is clear on one point. The equipment alone changes little. Drivers improve when a supervisor reviews events and coaches them, so the program, not the hardware, is what you are really buying.

What the tools record

Federal ELD rules require most commercial motor vehicle drivers to log hours electronically, but the mandate is about hours-of-service compliance. Cameras and harsh-event sensors are a voluntary add-on, and insurers treat them as separate from ELDs.

What the research says

The best evidence is on coaching. A study published in the Journal of Safety Research in 2017 by Bell and colleagues installed an in-vehicle monitoring system in 315 vehicles at two companies, local truck transportation and oil and gas support, and compared intervention and control groups over about two years. Risky driving behaviors fell significantly more when drivers got both in-cab warning lights and supervisor coaching with video than under lights alone or in the control group. Lights alone were not significantly different from the control group (study abstract). The authors concluded that supervisory coaching was effective feedback.

An earlier field evaluation funded by FMCSA and run by the Virginia Tech Transportation Institute, described by Hickman, Hanowski and Ajayi at the 2009 Driving Assessment Conference (paper), reported reductions in safety-related events of 37 percent at one carrier and 52.2 percent at another when video monitoring was paired with feedback and coaching. It involved two carriers over 17 weeks, so treat it as suggestive. Other widely quoted figures, such as projected lives saved from putting cameras on every truck, were commissioned by vendors and are modeled estimates, not observed results.

For a fleet manager the message is practical: budget for the review time and the coaching conversations, not just the devices.

How insurers use the data

At underwriting. Commercial auto submissions now ask whether the fleet uses telematics or cameras, what percent of units are equipped, who reviews the events and how often, and what happens after a flagged event. A fleet that can show event counts trending down and coaching records is giving the underwriter a reason to think its drivers are managed. Carriers may reflect that through credits within their rating plans, often through schedule rating, or simply through willingness to quote. There is no standard discount, so do not buy equipment for a promised premium reduction alone.

In usage-based programs. Some carriers price directly off the data. Progressive Commercial's Smart Haul program (program page, reviewed October 2026) is open to for-hire truckers with an ELD, a USDOT number and primary liability on a Progressive for-hire truck policy. Enrolling in the quote gives an immediate discount for granting data access, and the premium is then adjusted at each renewal from recent driving data, so it can move up or down. Progressive's page says customers on a Geotab, Motive or Omnitracs ELD qualify for the largest savings, quotes a minimum 5 percent for new business with a preferred ELD and says savings are not guaranteed. The program is not available in every state.

In claims. Video can establish who had the green light, whether the driver was braking, how fast the truck was going and what the other driver was doing. That can cut claim cost in two ways: disputed-liability claims settle on facts rather than guesses, and staged or exaggerated claims lose their footing. In a serious bodily injury case, the footage and the data trail are among the first things both sides ask for, which is why they matter in the large claims described in nuclear verdicts and social inflation: why liability costs keep rising. See also why commercial auto insurance keeps getting more expensive.

The evidence cuts both ways

A recorded clip of a driver on a phone, with a coaching alert that was never read, is not helpful to the defense. Plaintiffs' lawyers ask what the fleet knew about its driver and what it did about it. The conclusion is not to avoid monitoring. It is to set up the program so that every flagged event gets a documented response, and to talk with a defense attorney about retention before you need to.

Retention matters too. Under Federal Rule of Civil Procedure 37(e), a court can sanction a party that fails to take reasonable steps to preserve electronically stored information that should have been preserved for litigation; the harshest sanctions, such as an adverse-inference instruction, require a finding of intent to deprive (Rule 37, Cornell LII). Many telematics systems overwrite clips on a schedule. After any serious crash, the fleet needs a procedure to lock the footage and data before the loop overwrites it. That belongs in the accident procedure in what to do after an accident in a company vehicle.

Privacy and regulatory points

• Biometric laws. Driver-facing cameras that use facial recognition can raise the Illinois Biometric Information Privacy Act (740 ILCS 14) and similar laws. See Biometric privacy (BIPA) lawsuits and insurance and ask the vendor in writing what it collects.
• Audio. Recording cab audio is regulated by state wiretap laws, and some states require every party's consent. Many fleets disable audio or limit it to the moments around an event.
• Notice. Some states require written notice to employees about electronic monitoring. State privacy rules are covered in state privacy laws and what they mean for business insurance.
• Windshield mounting. FMCSA defines "vehicle safety technology" in 49 CFR 393.5 to include driver camera systems, performance or behavior management systems and GPS. Under 393.60(e)(1)(ii), such a device on the inside of a windshield must be mounted no more than 8.5 inches below the upper edge of the wiper-swept area and no more than 7 inches above its lower edge, and outside the driver's sight lines to the road and highway signs and signals. Check the vendor's installation against it.
• Data ownership. Know who owns the footage, how long the vendor keeps it, and how you export it if you change vendors.

Rolling out a program

1. Decide what you want the data to do: reduce crashes, defend claims, support underwriting, or all three.
2. Pick a vendor and get its data retention, export, ownership and biometric terms in writing.
3. Tell drivers before installation, explain what is recorded, and keep signed acknowledgements.
4. Tune thresholds for two to four weeks so managers are not buried in false alerts.
5. Set a coaching schedule, with a goal of reviewing flagged events within days, not months.
6. Document every coaching session and the outcome.
7. Write a litigation hold step into your accident procedure.
8. Report results to your broker before renewal, including the percent of fleet equipped and event trends.

A hypothetical fleet

Say a 20-van plumbing company installs dual-facing cameras. In the first month the system flags 200 events, mostly rolling stops and following-distance alerts, and the owner decides to review only the 30 most serious each week. Over six months the weekly count drops. The numbers in this example are invented to show the mechanism. When someone looks at the clips, repeat offenders become visible, the coaching is documented, and the owner has a record to show the carrier at renewal. Without that review, the same cameras would have produced 200 unread clips a month. A fleet of that type should also tie the program to a written building a fleet safety program that insurers notice and to its driver standards in Driver selection, MVRs and your commercial auto premium.

Key takeaways

• Telematics and cameras help most when a supervisor reviews events and coaches drivers; a 2017 Journal of Safety Research study found lights alone no better than control, and coaching plus lights better.
• Insurers ask about monitoring at underwriting, some price directly from the data (Progressive's Smart Haul adjusts premium at each renewal, up or down), and there is no standard discount.
• Video can protect a fleet in a disputed crash and hurt it if flagged events were ignored. Set up a documented response to every flagged event.
• Preserve footage and data after any serious accident; courts can sanction a party that fails to preserve electronic evidence.
• Check biometric, audio-recording, notice and windshield-mounting rules, and get the vendor's data terms in writing.
