What a fleet can put in place before a claim, what each measure does once one arrives and California's rules for cameras and tracking. Written for owners and fleet managers running up to 50 vehicles.
Quick answer
A fleet can't control other drivers, but it can control the evidence after a crash or a theft. That means forward and driver-facing dashcams, telematics, gated and lit yards with key control, DMV Employer Pull Notice enrollment with annual MVR reviews, a written driver policy and an accident kit. These can give the adjuster, the defense lawyer and the underwriter facts to work with against staged accidents and inflated claims, though none promises a lower premium. California also limits where a windshield camera can sit and how much footage an event recorder may keep.
A fleet can't control other drivers, but it can control what it knows after a crash or a theft. Forward and driver-facing cameras can record what happened. Telematics puts a time, a place and a speed on it. Gates, lights, yard cameras and key control make trucks harder to take. DMV's Employer Pull Notice program and annual MVR reviews help keep the driver list honest, a written driver policy shows the rules existed before anything went wrong, and an accident kit gets the facts down at the scene.
None of this promises a lower premium, and no camera wins a claim on its own. These measures can give the adjuster, the defense lawyer and the underwriter something solid to work with, and many underwriters ask which ones a fleet runs. For how the policy itself is built, see how a business auto policy works.

| Measure | What it does | Effort to run | The claim it helps with |
|---|---|---|---|
| Forward and driver-facing dashcams | Records the road and the cab, saving a clip on hard braking or an impact | Moderate: review flagged clips and coach from them, mount where VC 26708 allows and post the audio notice if the cab records sound | Disputed fault, staged collisions and rear-end claims where the other car stopped short |
| Telematics and GPS | Logs location, speed, braking and engine hours with a time stamp | Low to moderate: install once, then read the exception reports each week | Disputes over when and where a truck was, speed allegations and finding a stolen truck |
| Yard cameras, gates, lighting and key control | Makes trucks and trailers harder to steal or vandalize and records who came and went | A one-time build-out, plus a key log someone keeps current | Theft and vandalism of vehicles and trailers |
| Catalytic converter shields and VIN etching | Slows converter theft and ties a marked converter to its truck under California's resale rules | One-time, per vehicle | Converter theft and the repair that follows |
| DMV EPN and annual MVRs | Documents that you checked and tells you when a driver's record changes | Low: enroll once, read each report as it arrives | Allegations that the company kept an unsafe driver behind the wheel |
| A written driver policy | Sets who may drive, personal use, phones, passengers and take-home rules before anything happens | Low to write, steady to enforce | Permissive-use disputes and claims that the company had no rules |
| An accident kit in every cab | A checklist, an information card and a prompt to photograph the scene and count occupants | Low: stock it once, check it at inspections | Claims that grow after the scene: extra passengers, injuries or damage reported days later |
Cameras tend to do the most with coaching behind them. An FMCSA-sponsored study of onboard video monitoring found safety-related events fell 38.1% and 52.2% at two carriers; it measured events rather than crashes, and coaching was part of the program. Driver buy-in matters too: ATRI's 2023 survey put drivers' approval of driver-facing cameras at 2.24 out of 10, and approval rose 87% when footage was used proactively. For choosing cameras, see our post on dashcams and commercial auto claims; for MVR standards, see driver eligibility and MVR standards for fleets. The EPN rules are in our requirements guide's EPN section.
CHP counted 1,802 commercial trucks stolen in California in 2025, down only 5.06% in a year when thefts overall fell 24.3%, along with 7,331 trailers; 80.0% of the stolen commercial trucks were recovered. Nationally, NICB counted 16,660 catalytic converter theft claims in 2020 and 64,701 in 2022; thefts have fallen sharply since as metal prices dropped, though California still sees the largest share. Etching works with California's resale law: Under Vehicle Code 10852.5, a buyer may purchase a used converter only from a listed seller or from an owner whose title or registration matches the VIN marked on the converter. California hasn't made marking mandatory.
Theft of the truck, a trailer or a converter typically falls under the comprehensive side of physical damage coverage, and trailers generally need their own line on the schedule; see commercial trailer insurance. Tools taken from a truck usually aren't an auto claim; they fit on a separate tools and equipment policy. Our post on work truck theft risks by metro covers where thefts concentrate.

NICB names the common schemes. In a panic stop, a car slows or stops abruptly in front of a truck so the truck hits it from behind. In a drive down, another driver signals a truck to go ahead, then drives into it and denies ever signaling. In a swoop and squat, one car cuts in ahead of a second car, which brakes hard in front of the target; NICB calls the freeway version the most dangerous of all the schemes. A paper accident happens only in the claim file.
Commercial vehicles are on the list. California's Department of Insurance said in 2021 that stagers target high-value vehicles and named commercial vehicles among them, and in fiscal year 2023-24 its fraud division logged 12,559 suspected fraudulent auto claims. County district attorneys prosecute these cases too; Riverside County's, for one, runs a unit for staged and paper accidents.
Video is often what ends the argument. In a Santa Clara County case CDI announced in July 2026, a driver brake-checked a semi on US-101 and then claimed the truck had rear-ended him. The semi's dashcam had captured the whole incident, and he was convicted of a felony. Our post on staged collision fraud and how dashcams help has more cases.
ATRI's 2020 study of trucking verdicts found two patterns a fleet can plan around. The defense lost every case that involved an hours-of-service or logbook violation. And proven spoliation, meaning lost or destroyed evidence, almost always earned the plaintiff the jury's sympathy right away. A fleet with cameras therefore benefits from a rule for keeping what they record.

California's windshield rule, as amended effective January 1, 2026, generally allows a camera in three places: a 7-inch square in the lower corner farthest from the driver, a 5-inch square at the top center of the windshield or a 5-inch square in the lower corner nearest the driver and outside the airbag deployment zone.
The same section sets conditions for video event recorders. If the device records sound, post a notice that a passenger's conversation may be recorded. Footage may be stored for no more than 30 seconds before and after a triggering event. The registered owner or lessee owns the recordings, and an employee driving the vehicle for hire can get unedited copies free within 5 days of asking.
Under Penal Code 632, recording a confidential conversation takes the consent of every party, and violations can carry fines of up to $2,500. For a driver-facing camera with a microphone, that usually means the posted notice plus written notice to employees. A fleet that doesn't need cab audio can switch it off.
California's ban on electronic tracking devices doesn't apply when the vehicle's registered owner, lessor or lessee consents, so a business can generally track the trucks it owns or leases. An employee's personal car is a different case: The consent that counts belongs to its owner, the employee.
The CCPA's exemption for employee data expired at the end of 2022, so a covered business (one test is more than $26.625 million in annual revenue) generally owes employees notice of the personal information it collects, which for a fleet can include video and location data. A 2026 law, AB 1331, adds rules for workplace surveillance tools, including geolocation, and lets employees leave such a tool behind when entering a workplace bathroom. Its effective date hasn't been confirmed. None of this is legal advice; an employment lawyer can review your notices.
Our post on GPS and telematics for contractor fleets covers using the data well.

An underwriter mostly weighs what's in the submission. With the vehicle list, driver list and loss runs, send a short page that answers these:
Whether that page moves the price depends on the carrier and your loss history; what it can do is answer questions before they're asked. If you're starting from scratch, our guide to what a written fleet safety program does for your insurance walks through a first version, and our page on fleet insurance for 11 to 25 trucks covers how carriers look at fleets past ten trucks. When it's ready, you can start your fleet quote with the summary attached.
Under Vehicle Code 26708, a windshield-mounted video event recorder in California may store no more than 30 seconds of footage before and after a triggering event, and the registered owner or lessee owns the recordings.
Fleets often discover how long their cameras keep clips only after a crash, when the footage is already gone. Check retention on every camera and the telematics platform now and hold everything tied to an incident that day.
ATRI's 2023 survey found driver approval of driver-facing cameras rose 87% when footage was used proactively. Cameras tend to do the most when someone reviews flagged clips and coaches from them, not only after a claim.
A stolen truck, trailer or catalytic converter typically falls to comprehensive if the vehicle is scheduled with that coverage; an unlisted trailer usually has no physical damage to draw on. Tools lifted from the cab or bed generally go to an equipment policy instead.
Timing depends on the carriers and your loss history.
Have ready: vehicle list with VINs, driver list, current declarations page, loss runs.
