Cambridge Mobile Telematics

View

Cambridge Mobile Telematics provides a platform that monitors driving behavior using mobile sensors to track patterns like speed, braking, and phone usage. This technology allows insurance companies to offer usage-based policies where premiums are determined by actual driving performance rather than general demographics. By providing real-time data analytics and safety rewards, the company distinguishes itself from traditional insurers that rely on static risk assessments. The company's goal is to reduce accidents and improve road safety for everyone by encouraging and rewarding safer driving habits.

CMT launches freight broker safety platform with 90-day carrier driving data

Cambridge Mobile Telematics has launched Freight Safety Intelligence, a platform giving freight brokers access to recent driving data from participating carriers. Announced on 2 September, the system analyses driving behaviour from the previous 90 days to generate carrier-level safety scores. The platform uses data from carriers' existing telematics systems rather than requiring new hardware. Carriers can opt in and control what information they share. CMT says the 90-day analysis has been validated against actual accident risk, though validation methodology details were not disclosed. The launch follows a May Supreme Court ruling in Montgomery v. Caribe Transport II that allows lawsuits alleging negligent carrier selection by brokers to proceed under state law. In 2024, 5,218 large trucks were involved in fatal crashes in the US, down 3% from 2023 but up 30% from 2014.

CMT launches Freight Safety Intelligence to improve carrier selection.

CMT launches Freight Safety Intelligence to improve carrier selection. The platform uses recent driving behavior to give freight brokers a more current view of carrier safety performance. Sept. 2, 2026 Key takeaways. * Brokers can use 90 days of driving data to assess carrier safety before assigning freight. * Carriers voluntarily share telematics data and control what information they contribute. * A carrier-level safety score could make recent driving performance a factor in freight selection. Cambridge Mobile Telematics (CMT) recently launched Freight Safety Intelligence to give freight brokers current insights into carrier driving safety. The company, which develops telematics and AI technology for safer mobility, is expanding its road safety platform to the freight industry with a system that also gives carriers a way to demonstrate their safety performance. Freight Safety Intelligence measures carrier driving risk based on real-world driving behavior. Freight brokers can use the safety signal as part of their carrier selection processes to better understand driving risk before assigning freight. The platform uses data from carriers' existing telematics systems. Carriers voluntarily authorize their data through the platform and maintain control over what information they share. Sponsored recommendations. CMT analyzes driving safety from the previous 90 days and generates a carrier-level safety score that is validated against actual accident risk. The recent data is intended to give brokers a more current view of driving behavior than existing safety records. For carriers, the platform provides a way to use recent driving performance to demonstrate how safely they operate. CMT said this can help carriers differentiate themselves from competitors, strengthen broker confidence, and potentially compete for more business based on demonstrated safety performance. Freight Safety Intelligence builds on CMT's DriveWell Fleet platform, which launched in January 2026 for commercial fleets and their insurers. "Every day, millions of families share the road with commercial trucks, and every load moved by a safer carrier makes those families safer," said William V. Powers, co-founder and CEO of CMT. "For more than a decade, CMT has helped tens of millions of people become safer drivers, preventing over 126,000 crashes and 68,000 injuries. Freight Safety Intelligence brings that same approach to freight. When brokers can see which carriers drive the safest and reward them with more business, safety becomes key to how carriers grow. This changes the incentives for an entire industry and will make the roads safer for everyone." What this means for the trucking industry. Freight Safety Intelligence could give freight brokers another data point when evaluating carriers, particularly when traditional safety records do not reflect recent driving behavior. For carriers, the platform creates a potential business benefit from maintaining and demonstrating strong safety performance. The opt-in model also puts carriers in control of the telematics data they contribute. If brokers incorporate the resulting safety scores into carrier selection, recent driving performance could become a more visible factor in how carriers compete for freight.

Volvo wants to make you A safer driver - and lower your insurance bill.

Volvo wants to make you A safer driver - and lower your insurance bill. [email protected] (Iulian Dnistran) Thu, August 13, 2026 at 2:01 AM PDT An optional app will provide a safety score based on the driver's behavior, and higher scores could lead to lower insurance rates. * Volvo is taking a page out of Tesla's book when it comes to car insurance. * The Swedish automaker is launching an optional app that monitors how a car is driven. * Available on 2020-and-newer Volvos, the Safety Coach app will come up with a safety score, which could be linked to special insurance rates. Volvo is launching a new app that will monitor the driver's behavior behind the steering wheel and come up with a safety score for the previous two weeks. That score will then be used for usage-based offers from insurance companies that have partnered with Volvo, so people who get high scores in the app have the potential to slash their insurance costs. The Safety Coach app will be optional, and its rollout will begin this month in Sweden and Norway, with most Volvo models from model year 2020 getting access to the in-car app. A smartphone version will also be integrated into the Volvo Cars mobile app. Further down the road, the company aims to launch the app in the United States and other European markets, with insurance-related offers included in the rollout. The app, which is similar to Tesla's Safety Score approach, will monitor the driver's behavior in traffic, including braking, acceleration, and cornering. The app was built by Volvo Cars in collaboration with Cambridge Mobile Telematics (CMT), which describes itself as the world's largest telematics and AI company for safer mobility. "Our research shows that many accidents involve some form of surprise. What helps prevent that is predictability," said Mikael Ljung Aust, driver behaviour expert at Volvo Cars. "Staying within expected speed ranges and avoiding abrupt manoeuvres makes your driving easier for others to anticipate and reduces the risk of a collision. Supporting safe driver behaviours is a key piece of the puzzle we need to solve to reach zero collisions, and tools like Safety Coach can help turn these insights into safer everyday habits." After downloading the app, drivers can manage their own data. Volvo said that owners are not locked into the system after opting in for the first time, so they can opt out of sending their data to affiliated insurance companies. What's more, after opting out, drivers can opt in again at any time. In Sweden and Norway, owners who choose to share their driving behavior data will soon be able to make use of a special usage-based offer from insurance firm Volvia. The automaker has not disclosed which insurance company will handle customized offers in the U.S. when the Safety Coach app launches here. In Europe, the app is compatible with cars that have a Google-based infotainment system from model year 2020 onwards, and the same cars will likely make the cut in the U.S., too. These include the all-electric EX40, EC40, EX60, and EX90, as well as the combustion-powered XC40, S60, V60, XC60, XC90, and V90.
