US-based Cambridge Mobile Telematics (CMT) has launched a telematics product designed to support pricing and underwriting decisions in commercial motor insurance, according to a company press release.

The product, called DriveWell Fleet, enables insurers to incorporate driving data across a wider proportion of their commercial portfolios by combining data from connected vehicles with proprietary hardware for fleets that are not already equipped with telematics devices.

CMT said the offering is intended to address gaps in coverage, data consistency and programme integration that have limited the use of telematics in commercial motor insurance. Fewer than 5% of commercial motor policies are currently priced using telematics data, despite a significant proportion of vehicles already generating data through third-party telematics service providers (TSPs), the company said.

DriveWell Fleet allows insurers to access standardised, high-frequency driving data from multiple TSPs through a bring-your-own-device (BYOD) model. For vehicles without existing devices, CMT provides two hardware options to capture driving behaviour data.

William V. Powers, co-founder and chief executive of CMT – headquartered in Cambridge, MA – said the company was extending an approach previously used in personal motor insurance into the commercial sector. He said the aim was to “strengthen pricing decisions” and provide insurers with more consistent risk insights from fleet data.

For connected fleets, CMT’s platform integrates with TSPs including Samsara, Verizon Connect, Lytx, Netradyne and Linxup. The company said this currently covers more than 80% of the connected commercial vehicle market, with broader coverage expected later in the year. Fleets can enrol using existing devices, avoiding additional installation costs.

From a motor finance perspective, the product is positioned as a way for insurers to refine risk selection and pricing accuracy, potentially influencing premium levels and loss ratios across commercial motor portfolios. CMT said insurers can view vehicle- and fleet-level data through a central portal to support underwriting, segmentation and policy pricing.

Adam Kahn, chief business development officer at Netradyne, said the partnership allows insurers to “access high-quality driving data” and apply it to pricing and risk assessment, while maintaining a focus on fleet safety outcomes.

For fleets without embedded telematics, CMT offers Tag Pro and Tag Max devices. Tag Pro is aimed at smaller fleets and uses an adhesive, windscreen-mounted device that transmits data via a proprietary network, without requiring a mobile phone or separate cellular contract. Tag Max is designed for heavy and long-haul vehicles and uses LTE connectivity to provide more detailed risk data, also without complex installation.

CMT said another focus of DriveWell Fleet is simplifying consent and onboarding for commercial policyholders. The platform includes standardised opt-in processes intended to support data transparency while reducing administrative friction for fleets and insurers.

Drew Reynolds, chief executive of Linxup, said the integration enables smaller fleets to “translate safety data into insurance outcomes”, including potential premium benefits, through a single platform.

The launch reflects continued insurer interest in using telematics to support commercial motor underwriting, as carriers seek more granular data to inform pricing decisions and manage risk in fleet portfolios.
