Commercial auto remains one of the most challenging lines in construction insurance programs. The segment has reported underwriting losses for fourteen consecutive years, while claim severity has increased approximately 64% since 2015. Rising vehicle repair costs, medical inflation, and increasing liability awards have all contributed to the pressure on commercial auto results. For contractors whose programs include trucks, vans, service vehicles, and heavy equipment with road exposure, commercial auto is the line where rate increases have been most sustained and where underwriting scrutiny has intensified most significantly. Here are six things every construction company needs to understand to manage this line effectively in 2026.
1. The Line Has Been Unprofitable for 14 Consecutive Years and Carriers Are Reacting
The commercial auto market is not in a temporary correction. It is in a structural repricing driven by loss trends that have persistently outrun rate increases. Carriers have responded by tightening underwriting standards, reducing capacity for fleet accounts with adverse loss experience, and requiring documentation of risk management programs that was previously considered optional. A contractor who was written by the same carrier at the same general terms for five years should not assume those terms will remain available. Underwriting reviews are more rigorous, more documentation-intensive, and more likely to result in a material change to terms than at any prior point in recent history.
2. Nuclear Verdicts Are Driving Umbrella and Excess Costs as Much as Primary Auto
The impact of large jury verdicts in commercial auto extends beyond the primary layer. When a commercial vehicle accident results in a verdict that exceeds the primary auto liability limit, the excess and umbrella layers above the primary policy can also be exposed. Multimillion-dollar verdicts against commercial vehicle operators have increased pressure on these higher layers. In response, excess and umbrella carriers have restricted capacity for programs with significant commercial auto exposure and increased rates for umbrella towers that sit above commercial auto primary limits.
Contractors whose umbrella and excess structures were designed before the current nuclear verdict environment should review whether their attachment points and limits still reflect the actual exposure. An umbrella that attaches at $1 million of primary auto liability was sized for a verdict environment where $1 million resolved most serious incidents. In the current environment, that attachment point may be sitting in the middle of the range where serious verdicts are landing.
3. Telematics Is Now an Underwriting Requirement, Not a Best Practice
Carriers underwriting commercial auto for contractor fleets are increasingly treating telematics as a core underwriting input rather than an optional safety measure. Accounts that can provide telematics data showing driver behavior trends, including speeding frequency, hard braking events, distracted driving indicators, and miles driven per vehicle, may receive different underwriting consideration than accounts without this information. The difference can be significant. Fleet accounts with documented telematics programs and favorable driving data may have access to terms that are not available to accounts without comparable documentation.
The practical implication for contractors who have not implemented telematics is that the premium differential between telematics-equipped and non-equipped fleets is now large enough to justify the investment on insurance cost savings alone, before the safety and operational benefits are considered. For contractors evaluating telematics platforms, the key underwriting input is behavioral data, not just GPS location. Carriers want to see what drivers are doing, not just where vehicles are.
4. Driver Qualification and MVR Monitoring Are Being Evaluated at Renewal
The annual motor vehicle record check is no longer the only driver qualification measure contractors should consider in the current market. Carriers are increasingly evaluating whether fleet accounts use continuous MVR monitoring programs that automatically flag changes to a driver’s record between annual reviews. A driver who receives a DUI conviction or accumulates moving violations between scheduled MVR checks can create an exposure that the employer may not know about or be able to address promptly.
Written driver qualification standards are also being evaluated. Carriers want to see documented criteria that define which violations disqualify a driver from operating company vehicles, how violations are reviewed and acted upon, and what training or intervention is required when a driver’s record changes. Accounts with documented programs receive more favorable treatment than those relying on informal management judgment.

5. Vehicle Repair Costs Are Pushing Actual Cash Value Settlements Lower Than Replacement Cost
Modern commercial vehicles, particularly trucks equipped with advanced driver assistance systems, cameras, and sophisticated electronic components, can be significantly more expensive to repair than older vehicles. A rear-end collision that might have resulted in a $4,000 repair on a 2018 truck could cost $12,000 to repair on a comparable 2024 model because of the sensors, cameras, and bumper-integrated electronics that may need to be replaced and recalibrated. When repair costs approach or exceed a vehicle’s actual cash value, the insurer may declare it a total loss. The resulting ACV settlement may be significantly less than the cost of replacing the vehicle in the current used vehicle market.
Contractors who carry commercial auto coverage on actual cash value terms for older vehicles in their fleet should evaluate whether the ACV of those vehicles, given current market conditions, adequately reflects replacement cost. The gap between ACV and replacement cost on a truck that is five or more years old can be substantial, and that gap falls entirely on the fleet operator in a total loss scenario.
6. Check Hired and Non-Owned Auto Exposure
Employees may use their own cars to drive to job sites, pick up materials or make other work-related trips. Contractors may also rent vehicles when a project requires them. If a crash occurs during one of those trips, the business could face a liability claim even though it does not own the vehicle.
Hired and non-owned auto (HNOA) coverage is designed to address certain liability claims arising from the business use of rented vehicles or vehicles the business does not own. Coverage depends on the policy’s terms and how the vehicle is being used, so contractors should review these exposures alongside their commercial auto coverage. HNOA generally does not pay to repair an employee’s personal vehicle.

Frequently Asked Questions
Why is commercial auto the most expensive line in a contractor’s insurance program?
Commercial auto has reported underwriting losses for fourteen consecutive years as claim severity has increased faster than premium levels. The primary cost pressures, including rising vehicle repair costs, medical inflation, and exposure to large jury verdicts in commercial auto cases, have not eased. In response, carriers have increased rates, tightened underwriting standards, and reduced capacity for fleet accounts with unfavorable loss experience.
What do commercial auto underwriters evaluate for contractor fleet accounts in 2026?
Underwriters evaluate loss history, driver qualification standards, MVR monitoring frequency and process, telematics adoption and behavioral data, vehicle maintenance records, and the written safety policies governing driver behavior. Accounts that can document disciplined risk management across all of these categories receive materially better terms than those with clean loss histories but no supporting documentation.
What is hired and non-owned auto coverage and do contractors need it?
Hired and non-owned auto coverage provides liability protection when a contractor’s employees use personal vehicles for business purposes or when the company rents vehicles it does not own. It fills the gap that a standard commercial auto policy leaves for non-fleet vehicles used in connection with the business. Most contractors have some exposure to this risk, and HNOA coverage is typically inexpensive relative to the liability it addresses.
