Drowsy driving is a stubborn, under-policed risk in heavy trucking. Hours-of-service rules can’t guarantee alertness, and there’s still no breathalyzer-style roadside test for sleepiness. That’s why fleets and OEMs are turning to vision-AI driver monitoring—tracking blink rate, gaze, head pose, and micro-fatigue cues—to warn, record, and ultimately reduce catastrophic crashes.

Below are three companies that stand out right now—what they actually have under contract, how they differ, and which U.S. carriers are adopting (or likely to adopt) these tools next.

1) Seeing Machines (LSE: SEE | OTC: SEEMF) — Cognitive Vision with a New U.S. Beachhead

Why they stand out
Seeing Machines has spent decades tuning eye-/face-tracking for fatigue and distraction across aviation, rail, automotive, and heavy vehicles. Its Guardian Gen-3 is the fleet product; the same science also powers OEM interior sensing.

Recent contracts / traction

• First U.S. fleet deal via Mitsubishi Electric Automotive America (MEAA): Seeing Machines signed its first Guardian Gen-3 customer through MEAA’s new referral program (fleet: Savannah Transport). That validates a North-American channel beyond pilots.

• Broader MEAA collaboration: MEAA is now an official referral partner to accelerate Guardian Gen-3 across the Americas.

Why fleets care
Guardian combines camera-based fatigue/distraction detection with real-time driver coaching and fleet alerts—exactly what insurers and safety teams want as proof of “fitness to drive.”

2) Smart Eye (OMX: SEYE) — OEM-Grade DMS, Now Crossing into Trucks (Affectiva inside)

Why they stand out
Smart Eye is a long-time OEM supplier for driver/occupant monitoring; its 2021 acquisition of Affectiva added “emotion AI” and nuanced cognitive-state assessment to the stack.

Recent contracts / traction

• Volvo Trucks & Buses: A multi-year deal to supply driver-monitoring for commercial vehicles—a marquee validation in heavy-vehicle production.

• Volvo’s latest DMS announcement (2025): Volvo Trucks detailed an upgraded Driver Alert Support with a new eye-tracking camera for drowsiness/inattention—evidence that OEM-grade DMS is moving quickly into truck lines.

• Automotive base: Smart Eye software powers DMS in multiple passenger-car programs (e.g., Volvo Cars EX90), strengthening scale and maturity.

Why fleets care
OEM-integrated DMS means trucks can ship “fatigue-ready” from the factory, simplifying fleet rollout compared with aftermarket hardware.

3) Lytx — U.S. Fleet Workhorse Adding Fatigue AI at Scale

Why they stand out
Lytx is ubiquitous in American fleets with its DriveCam platform. In July–Sept 2025, Lytx rolled out a new Fatigue Detection module and reported rapid early adoption.

Recent contracts / traction

• Fleet adoption figures: Within weeks of launch, more than 23,000 vehicles enabled Lytx Fatigue Detection, combining machine vision, AI, and human review.

• Named carrier programs: U.S. majors continue standardizing on AI dashcams—e.g., C.R. England outfitting its entire fleet with Lytx event recorders, while peer carriers upgrade to AI cams.

• Long-time customers: Carriers like NFI publicly discuss their inward-facing camera programs with Lytx, underscoring durability and scale.

Why fleets care
Lytx is already embedded in U.S. operations; flipping on fatigue analytics is a software toggle plus calibration—not a net-new hardware program.

Who’s Adopting in the U.S.—and Who’s Likely Next?

Already adopting / publicly disclosed moves (examples):

• C.R. England — outfitting the entire fleet with Lytx AI-powered event recorders (driver-risk and distraction detection).

• J.B. Hunt — extensive camera deployment across its Class-8 fleet (forward-facing, with driver-facing expansion discussed in company updates).

• NFI Industries — long-time inward-facing cameras with Lytx.

• Seeing Machines (Guardian) U.S. fleet beachhead — first MEAA-referred Savannah Transport contract signals early adopter momentum among midsize for-hire fleets.

Carriers most likely to adopt next (why):

• Large, safety-forward Trucking Alliance members (e.g., J.B. Hunt, Knight-Swift, Werner, Schneider) historically commit to advanced safety tech and have publicly supported stronger safety standards—making them natural adopters of fatigue analytics as accuracy improves.

• Fleets already standardized on AI dashcams (Lytx, Samsara, Netradyne) can enable fatigue/distraction features faster via software updates—expect accelerated uptake among these platforms’ customers.

Regulatory tailwind: FMCSA research continues on multi-modal fatigue detection; meanwhile, OEMs in Europe face GSR deadlines to include distraction/fatigue monitoring by July 2026—pressure that spills into North American spec sheets.

Roadside vs. In-Cab: What Comes First?

• Near-term reality: In-cab detection dominates rollouts (OEM or aftermarket). It’s already happening at scale (Lytx) and entering truck production cycles (Volvo/Smart Eye).

• Mid-term possibility: Roadside screening (weigh-stations/gantries) could complement in-cab systems for spot checks—especially where regulators want independent validation. Proof-of-concepts will likely piggyback on existing imaging infrastructure before any mandates.

Quick Scorecard

Bottom Line

• If you want OEM-level fatigue sensing built into the truck, Smart Eye (with Affectiva tech) has momentum through Volvo and Tier-1s.

• If you want fast U.S. fleet activation, Lytx has the installed base and just switched on Fatigue Detection at scale.

• If you want aftermarket precision with fresh U.S. channel access, Seeing Machines is now landing North-American fleets via MEAA—a meaningful step from pilot to production.

As infrared sensors, eye-tracking, and AI mature, the eyes that never sleep may do more than watch—they’ll coach, document, and prevent. For drivers, that could mean fewer false accusations and more backup when fatigue really does creep in. For fleets and the public, it means safer highways.
