The highest 10% of drivers ranked as highest threat by Samsara’s Threat Mannequin accounted for 47% of crashes in a brand new report launched by the corporate.
The discovering is a part of Samsara’s new Compounding Threat Report, which examines how combos of driving behaviors and different elements can contribute to elevated crash threat. The corporate says the analysis might help fleet managers determine the place to focus restricted teaching sources.
“The actual key takeaways are that 10% of drivers account for almost half of all crashes, 30% account for greater than three-fourths of crashes. So who you coach, who you zoom in on, actually, actually issues,” mentioned Arpan Podduturi, Samsara VP of AI security.
Compounding Threat Report
Samsara’s Compounding Threat Report appears to be like at how totally different driving behaviors and different elements can mix to have an effect on crash threat relatively than simply remoted occasions.
The report relies on Samsara’s Threat Mannequin, which evaluates greater than 50 elements throughout areas together with driving conduct, publicity, situational context and driver growth. The mannequin appears to be like at elements reminiscent of dashing, harsh braking, distracted driving and cell phone use, in addition to situations reminiscent of evening driving and climate situations.
As an alternative of evaluating every security occasion by itself, the mannequin appears to be like at how these elements happen collectively. Samsara refers to this as “compounding threat.”
“It’s like the mix of dashing plus it’s raining. Plus, it’s darkish out. Plus, you’re on the finish of your shift, and people issues compound in methods which are actually harmful,” Podduturi mentioned.
The report discovered that combos of behaviors have been related to greater ranges of threat than particular person behaviors alone. Drivers exhibiting cell phone use alone have been 2.7 occasions extra more likely to fall into the mannequin’s highest threat tier than the general driver inhabitants. That determine elevated to 4.5 occasions when cell phone use was mixed with harsh braking and 5.4 occasions when cell use, distraction and harsh braking have been current collectively.
The report additionally discovered associations between particular person behaviors and crash threat. Harsh braking was related to a 1.8 occasions greater chance of a crash, whereas cell phone use and distracted driving have been every related to a 1.7 occasions greater chance. Dashing occasions have been related to a 1.5 occasions greater chance.
Samsara mentioned the Threat Mannequin ranks drivers by relative threat and isn’t designed to foretell whether or not a selected driver will crash on a specific day. The findings describe statistical associations and don’t set up that the behaviors themselves induced a crash.
Utilizing threat knowledge for teaching
The Threat Mannequin additionally powers Samsara’s new Teaching Precedence characteristic, which is designed to assist fleet managers resolve the place to focus their teaching efforts.
Teaching Precedence brings the mannequin’s threat elements right into a single view, permitting managers to see the drivers, behaviors and different elements contributing to elevated threat.
“These are the highest drivers that you must prioritize to educate them. After which we’re saying you must coach them on behavioral patterns, not remoted occasions,” Podduturi mentioned.
As an alternative of responding to particular person alerts as they happen, managers can use the broader threat profile to determine recurring patterns and decide the place extra teaching could also be wanted.
“It’s who wants the human-to-human teaching, and the place are you able to automate? I feel that’s actually the important thing factor that fleets have to internalize,” Podduturi mentioned.
The mannequin additionally confirmed a possible sign earlier than crashes occurred. When evaluating drivers who have been subsequently concerned in a crash with those that weren’t, Samsara mentioned the mannequin prioritized the crash-involved driver about three out of 4 occasions. The consequence held throughout each next-day and seven-day analysis home windows.
A concentrate on driver security
Samsara mentioned the findings are supposed to provide fleets one other option to method driver security by figuring out patterns that will warrant intervention earlier than a crash.
Separate evaluation recognized aggressive driving, distracted driving and speeding-related patterns as probably the most constant and credible behavioral contributors to crash threat, in keeping with Samsara. Different elements, together with evening driving, freezing temperatures and concrete publicity, can amplify threat however are usually not teaching targets on their very own.
The corporate mentioned Teaching Precedence is meant to assist managers focus their time on the behavioral patterns most related to elevated threat, whereas self-coaching can reinforce safer habits throughout the remainder of the workforce.
The report relies on aggregated knowledge used to coach and consider Samsara’s Threat Mannequin from July 1 by way of Dec. 15, 2025. The dataset spans drivers and fleets throughout a number of industries and areas.
Samsara’s broader aim is to make use of the info to assist fleets transfer from reacting to particular person security occasions towards figuring out patterns of conduct and focusing on teaching the place it might have the best impression.
