Kodiak Will Drop Mirrors From Its Driverless Trucks, Riding Stoneridge's FMCSA Exemption

Stoneridge (NYSE: SRI) and Kodiak AI (Nasdaq: KDK) announced the collaboration from Novi, Michigan on Oct. 28. It starts with MirrorEye — exterior cameras feeding in-cab high-definition displays, the cameras housed in a compact wing above the cab door — on newly deployed Kodiak Driver trucks. Everything past that is exploratory: more Stoneridge hardware, better on-platform data processing. No volumes, no terms.

The concrete piece is the mirror. Kodiak's SensorPods already stand in for side mirrors, but until now have had to carry real rear-vision mirrors too, because U.S. rules require them. Kodiak hardware SVP Jamie Hoffacker called the integration "an important component of Kodiak's preparations for the safe deployment of driverless technology at scale." Dropping the mirrors, the companies say, makes the pods smaller, lighter, more aerodynamic and easier to replace.

Mirror-delete in the U.S. does not rest on a rewritten standard but on a permission. Stoneridge's camera monitor system was the first to win an FMCSA exemption authorizing carriers to run MirrorEye-equipped trucks without conventional rear-vision mirrors, and the agency renewed it in 2024 for another five years.

That matters to anyone speccing against a trade cycle longer than the exemption term. A rule holds until it is changed; an exemption is granted for a period and must be renewed. A fleet that deletes mirrors is operating on a clock.

Reading this as driverless-only equipment would be the mistake. Stoneridge says it has built more than 200,000 MirrorEye systems globally since 2020, supplies six global OEM programs, and has retrofit installations with more than 40 fleet partners in North America. The trade coverage frames it as an autonomy story, but that installed base is overwhelmingly conventional trucks with drivers in them.

That is what changes the parts conversation. A mirror assembly is a commodity — head, glass, arm, bracket, a dozen sources for each. A camera monitor system is a matched set of camera wing, display, harness and mounting hardware, tied to a specific OEM program and model year. A cracked lens or a failed display puts a truck down the same way a smashed mirror does; the fix is just not on a shelf at every counter.

If you run camera-equipped tractors, or are about to spec them, do the parts homework before the failure. Pin down the camera, display and harness numbers for your make and model year now — model-year specs and fitment by make will confirm what the truck actually shipped with, because those six OEM programs do not share hardware. Then check whether those numbers carry an interchange, since these components supersede quietly between model years and ordering the old number costs a day.

For trucks still on mirrors, nothing here obliges a change. But if a camera system is going on your next spec sheet, price the replacement parts, not just the option. And if you are already chasing an intermittent display or a dead feed, work the symptom first: it can be the camera, the harness or the display, and those are three different orders. Diagnostic guides by symptom will narrow it faster than a parts order will.
