For years, fleet safety meant reacting to single events. A hard brake. A speeding ticket. A near-miss caught on camera. New industry data on driver risk patterns suggests that approach misses most of the real risk sitting in your fleet, and it’s changed how we think about coaching with the fleets we support. 

The Data Behind the Shift 

We’ve been watching this trend closely. A recent analysis of crash and driving behavior data, collected across the back half of 2025, found that the riskiest 10% of drivers account for 47% of all crashes. Widen that to the riskiest 30% of drivers, and the number jumps to 76% of crashes. Most of your risk sits with a small, identifiable group. 

The multiplier effect is just as striking. Mobile phone use alone makes a driver 2.7 times more likely to land in the highest risk tier. Add harsh braking, and that climbs to 4.5 times. Add distraction on top of both, and it reaches 5.4 times. One risky habit is a warning sign. Several stacked together predict a crash weeks before it happens.

Why Single-Event Alerts Fall Short 

A traditional alert system flags a single moment. It buzzes when a driver brakes hard, or crosses a speed threshold. That’s useful, but it’s reactive by design. It tells you what already happened. It doesn’t tell you which drivers are quietly building toward a serious incident. 

Compounding risk models work differently. They look at patterns across weeks rather than isolated moments. That’s the shift Commercial Carrier Journal covered in its recent breakdown of the industry’s crash data: safety technology is moving from “what just happened” to “who’s headed for trouble.

You Already Have This Capability 

Here’s the part worth saying plainly: if you’re running Geotab, you don’t need to switch platforms to get pattern-based insight. Geotab’s safety center, driver scorecards, and exception reporting already track compounding behaviors across your fleet. That includes phone use, harsh events, and other risk indicators layered together well beyond single triggers. 

Pairing that data with dash camera footage gives you the full picture: which drivers are trending toward risk, and video evidence of what’s happening in the cab. Combined with a program built around recognizing and coaching your safest drivers, you get both ends of the safety equation in one system.

Better Prioritization Beats More Alerts 

The real opportunity here is sharper prioritization, well beyond another layer of alerts. Most fleets don’t lack visibility into risky behavior. They lack a clear answer to a simple question: which drivers should we coach first? A fleet that focuses limited coaching time on its highest-risk 10% addresses the group tied to nearly half its crash risk. 

Northern BI can help you set up Geotab’s driver risk and exception reporting to focus coaching time where it prevents the most incidents. Ask us for a consultation to review your current safety scorecard setup.
