PlacardPro is the compliance platform built for professional HAZMAT drivers and fleet safety managers. One scan of a Bill of Lading returns an instant PASS, WARNING, or FAIL against 49 CFR federal hazardous materials regulations — with exact citation references and required placard specifications. BUILT FOR THE CAB, NOT A DESK Every screen is designed for gloved hands, bright sun, and time pressure. Core actions take three taps or fewer. No compliance degree required. WHAT PLACARDPRO DOES • Scan any Bill of Lading with your phone camera • AI-powered OCR extracts hazmat line items automatically • Validates each item against 49 CFR Part 172 in real time • Returns PASS / WARNING / FAIL with the specific regulation cited • Displays exact placard requirements per DOT Table 1 and Table 2 • Full scan history stored securely for your carrier account • Works in low-signal areas with offline validation capability • CHEMTREC emergency line (1-800-424-9300) one tap away from Settings FOR FLEET SAFETY MANAGERS PlacardPro's web-based fleet console at placardpro.ai gives safety managers complete visibility and control over their fleet's hazmat compliance — without requiring drivers to learn any new software. REAL-TIME COMPLIANCE DASHBOARD See every BOL scan across your entire fleet as it happens. The dashboard surfaces total scans, pass rate, failed scans, and active driver count — updated in real time. Safety managers can search scans by driver name, shipper name, or load number to investigate specific incidents fast. SHIPPER COMPLIANCE REPORTING PlacardPro tracks which shippers are the source of your BOL violations. The shipper report ranks every shipper your fleet has loaded from by pass rate and surfaces the specific violations each shipper produces most often. When a shipper consistently generates non-compliant BOLs, you have the documented data to push back. DISPUTE AND OVERRIDE WORKFLOW When a driver believes a scan result is incorrect, they can flag it for manager review directly from the app — with a reason code attached. Fleet managers review flagged scans, view the original BOL image, and either confirm the fail, override it to pass, or dismiss the dispute. Every decision is logged with a timestamp and the manager's name for a complete audit trail. YOUR VIOLATION EXPOSURE, QUANTIFIED The dashboard shows your fleet's overall pass rate, total scans, and failed scans in real time. That number is the most important compliance metric your fleet has — and until PlacardPro, most carriers didn't have it at all. A carrier running an 85% pass rate on BOL scans has a measurable, documented PHMSA exposure problem. A carrier running 97% has documented evidence of a functioning compliance program — which matters when an inspector shows up. BILLING AND SEAT MANAGEMENT Add or remove driver seats directly from the console. REGULATORY COVERAGE PlacardPro validates against: • 49 CFR Part 172 — Hazardous Materials Table • DOT Placard Table 1 (always-placard materials) • DOT Placard Table 2 (1,001 lb threshold rule) • PHMSA Poison Inhalation Hazard (PIH) requirements • Proper shipping name, hazard class, packing group, and UN number verification WHY IT MATTERS A single PHMSA violation can cost $15,000 to $102,348 per incident. PlacardPro pays for itself the first time it catches a BOL error before a driver leaves the yard. SUBSCRIPTION PlacardPro requires an active carrier account provisioned by your fleet safety manager. Drivers are added by account — no individual purchases required. Contact your fleet administrator or visit placardpro.ai.
