The commercial auto insurance market remains challenging, with underwriting losses persisting over the last 14 years despite rising premiums.

SambaSafety recently released the 2026 edition of its annual Driver Risk Report, which examines the driver safety trends insurance carriers and commercial fleets are facing in 2026. They attribute the tough commercial auto market in part to escalating claim severity, which they report has increased 64% since 2015.

Liability losses have increased at a rate beyond general economic inflation, SambaSafety says, driven by social inflation and nuclear verdicts. Increasingly complex vehicles have also contributed to increasing commercial auto losses, as tech-heavy vehicles become more common in fleets. Vehicle sensor systems are often interconnected and can be embedded throughout the vehicle, which makes them more difficult and expensive to repair.

SambaSafety's 2026 report also examines the ways in which labor dynamics and driving behavior influence risk. Persistent driver shortages have led to fleets onboarding less-experienced crew in order to keep their businesses rolling, which puts them at higher risk of more frequent and severe losses.

Fleet managers also face magnified risk due to evolving driving behaviors, including speeding and participating in distracting activities, which contribute disproportionately to more severe incidents. These behaviors, SambaSafety notes, present risk that is difficult for insurance underwriters to price accurately.

In the slideshow above, we'll look at six takeaways from SambaSafety's latest Driver Risk Report that offer insights into the state of commercial driving risk in 2026.
