Compliance Baked Right Into the Cab

Rand McNally and Platform Science put hazmat-aware routing in the cab, no extra hardware required

3 Nov 2025

Getting the route wrong on a truck carrying dangerous goods is not a minor inconvenience. A wrong turn into a restricted tunnel, or onto a weight-limited bridge, can bring regulatory fines, safety incidents, and hours of lost time. Until recently, drivers relied on their own knowledge or separate reference systems to avoid such outcomes. That is changing.

In October 2025, Rand McNally announced a partnership with Platform Science to bring its hazmat-aware navigation system to the Virtual Vehicle Marketplace. Fleets already using the Platform Science connected-vehicle ecosystem can activate the tool instantly, without new hardware, alongside existing telematics and electronic logging workflows. The move is part of a broader push to collapse fragmented in-cab technology into a single platform.

The navigation layer draws on eight decades of commercial road data and contains roughly a third more truck-specific attributes than standard consumer maps. Low-clearance bridges, weight limits, and hazmat-restricted routes are updated in real time with traffic and weather data. The practical value lies in automation: constraints are factored into route calculations without the driver needing to consult a separate system or rely on memory.

Platform Science completed its acquisition of Trimble's telematics business in February 2025, with Trimble becoming a strategic investor. The transaction extended the platform's reach across commercial fleets of all sizes and gave application developers a unified environment to deploy in-cab tools without changing vehicle hardware.

For carriers of dangerous goods, the appeal is straightforward. Combining navigation, telematics, and compliance data in one architecture reduces the margin for human error and produces a continuous digital record useful for regulatory audits. As workforce pressures and compliance demands tighten simultaneously, that kind of integration is becoming less a competitive advantage and more a basic requirement.
