For years, fleet managers have been asking a simple question: Are camera systems legal in commercial trucks? With that question, they have run into a confusing maze of state laws, federal exemptions, and windshield obstruction rules that often contradict one another. That maze just got smaller. On January 1, 2026, California’s Senate Bill 506 took effect, revising Vehicle Code §26708 to align the state’s dash cam placement rules for heavy trucks with the federal standard set by the Federal Motor Carrier Safety Administration (FMCSA).
The short answer is yes. Camera systems are legal in commercial trucks across all 50 states. But the rules around where you mount them, what they record, and who must consent vary significantly. SB 506 is the most important regulatory update fleet operators have seen in years, and it directly affects how trucks over 10,000 pounds can use AI dash cams, video event recorders, and multi-camera systems.
Here’s what the law changed, what it means for your fleet, and how to stay compliant.
What SB 506 Actually Changes
Before SB 506, California’s windshield obstruction law was one of the strictest in the country. It permitted “video event recorders” only in narrow zones, which is generally a seven-inch square in the lower passenger-side corner or a five-inch square in the lower driver-side corner of the windshield. Modern AI dash cams designed for heavy trucks often didn’t fit cleanly into those zones, and fleets sometimes received citations even when their cameras were operating exactly as the federal government intended.
SB 506 fixes that conflict. The bill broadens the existing exception to apply to “vehicle safety technology” installed on specified commercial vehicles, including motor trucks of three or more axles that are more than 10,000 pounds gross vehicle weight rating, provided the equipment is otherwise in compliance with federal regulations.
In plain English: if your dash cam meets the FMCSA’s federal placement rules under 49 CFR 393.60, it now meets California’s rules too.

The Federal Standard: 49 CFR 393.60
The federal rule that California is now mirroring was finalized by FMCSA in March 2022. It allows vehicle safety technologies, a category that includes dash cams, lane departure warning systems, forward collision warning systems, and driver camera systems, to be mounted on the interior of a commercial motor vehicle’s windshield, provided they sit:
- Not more than 216 mm (8.5 inches) below the upper edge of the area swept by the windshield wipers
- Not more than 175 mm (7 inches) above the lower edge of the area swept by the windshield wipers
- Outside the driver’s sight lines to the road and to highway signs and signals
That 8.5-inch figure is significant. The original federal rule allowed only 100 mm (4 inches) of clearance below the upper edge of the wiper sweep, which made it nearly impossible to mount many modern AI camera systems without an exemption. The 2022 update, now mirrored by California, gives fleets the flexibility to install equipment where it actually works best.

Why This Matters for Fleet Safety
Regulatory clarity isn’t just a paperwork win. It removes one of the last excuses for delaying a safety camera rollout. And the safety case is overwhelming.
The National Highway Traffic Safety Administration (NHTSA) estimated that 18,720 people died in motor vehicle traffic crashes in just the first half of 2024, a grim reminder of what’s at stake every time a heavy truck pulls onto the highway. Camera-based safety programs measurably reduce that toll. Real-world fleet data tells the same story. Vestige customer SalSon Logistics, a Newark-based carrier with 750 trucks, saw insurance payouts fall from more than $9 million in 2017 to under $200,000 in 2019 after deploying AI-powered cameras across its fleet. Accidents in the same period dropped from 418 to 24.
“We’re not flying blind anymore. Vestige gave us eyes.” — John Lampasona, Vice President of Safety and Compliance, SalSon Logistics
That kind of return is why insurers are increasingly building camera requirements into their underwriting decisions. Beyond crash reduction, video evidence is one of the most effective tools fleets have against fraudulent claims. This is a category that the Coalition Against Insurance Fraud estimates costs Americans more than $308 billion annually across all sectors.

What “Legal” Looks Like in Practice
Beyond windshield placement, three other compliance areas deserve attention:
- Audio recording consent. California, Illinois, and Pennsylvania are two-party consent states, meaning every person whose voice is captured in the cab must be informed that an audio recording is taking place. Most fleets address this with signed driver acknowledgments and visible cab signage.
- Driver-facing cameras. These are legal in all 50 states, but transparency is essential. Notify drivers in writing, explain how footage will be used, and tie the program to coaching rather than punishment. Fleets that take this approach see far higher driver acceptance.
- Footage retention. There is no single federal retention standard, but risk advisors generally recommend storing event-triggered footage for several years to cover statutes of limitation on civil claims.
A properly designed commercial truck camera system handles these requirements automatically by flagging events, securing the footage chain of custody, and giving safety managers controlled access without exposing raw video to misuse.
Beyond the Single Dash Cam
The vehicles most affected by SB 506, which are three-axle motortrucks over 10,000 pounds, are exactly the vehicles that benefit most from multi-camera coverage. A single forward-facing dash cam captures the road ahead, but blind spots on the sides and rear of a heavy truck are where many of the most expensive incidents occur, including pedestrian and cyclist strikes, lane-change collisions, and staged accidents.
Modern multi-camera systems for trucks typically combine a forward road-facing camera, a driver-facing camera with AI behavior detection, and side or rear cameras to deliver 360-degree visibility. When that footage is paired with GPS data and event-based triggers, fleet managers can reconstruct any incident in seconds rather than days.
For Elite Collateral Recovery, that comprehensive coverage proved essential after one of their drivers faced gunfire while towing a vehicle. The cameras captured the full incident, supported the driver’s 911 call, and exonerated him in the investigation.

Get Compliant and Get Protected
SB 506 didn’t just clarify a regulation. It removed a barrier between fleet operators and the technology that demonstrably reduces crashes, defeats fraudulent claims, and protects drivers from false accusations.
Vestige helps fleets across trucking, towing, transit, and field services deploy AI-powered cameras that meet every federal and state placement requirement out of the box. Whether you operate five trucks or five hundred, our team will walk you through the right configuration for your vehicles and your jurisdictions.

Frequently Asked Questions
Yes. Dash cams are legal in all 50 states, but mounting and audio rules vary. The FMCSA’s 49 CFR 393.60 sets the federal placement standard for commercial motor vehicles, and California’s SB 506 brings the state’s rules for heavy trucks into alignment with that standard as of January 1, 2026.
For commercial vehicles meeting FMCSA’s vehicle safety technology definition, the device must be mounted within 8.5 inches below the top of the wiper-swept area, within 7 inches above the bottom of that area, and outside the driver’s direct sight lines.
You don’t need driver consent for video, but in two-party consent states such as California, Illinois, and Pennsylvania, you must inform any person whose audio is recorded. Most fleets handle this with written acknowledgments at hire and clear cab signage.
There’s no federal mandate, but industry best practice is to retain event-triggered footage for several years to cover the statute of limitations on personal injury and property damage claims.
