Insurance Costs Climb as State Laws Erode Federal Preemption Shield

Why are trucking insurance costs rising faster than claim frequency?

Carrier insurance premiums are climbing because of state-level legislative changes and poor underwriting discipline, not just large jury awards. Myles Oppenheimer, chief risk officer at Cover Whale, calls the current market turmoil a "self-inflicted wound" that traditional insurers cannot manage. The recent Supreme Court decision eliminating federal preemption in broker liability cases has accelerated the problem by opening carriers and brokers to state-by-state legal exposure.

The Supreme Court ruling in May allowed plaintiffs to sue freight brokers for negligence in carrier selection under state tort law, stripping away the federal shield that had limited broker liability for decades. That decision expanded liability for brokers and raised insurance costs for carriers who work with them. Oppenheimer argues the ruling is part of a broader legislative environment that fragments risk across state lines, making it harder for insurers to price policies accurately.

How state laws fragment the insurance market

Traditional trucking insurance relies on federal preemption to create uniform risk pools across state lines. When states pass their own liability standards, jury instructions, and damage caps, insurers lose the ability to model risk at scale. Oppenheimer says this legislative patchwork forces underwriters to treat each state as a separate market, raising administrative costs and reducing the capital available to write new policies.

The result is tighter capacity. Carriers with clean CSA scores and modern safety systems still face double-digit premium increases because insurers cannot distinguish low-risk fleets from high-risk ones when state laws vary. Small fleets operating in multiple states pay the highest premiums because they cross the most legal jurisdictions without the negotiating power of large carriers.

Underwriting discipline breaks down

Oppenheimer points to a lack of underwriting discipline as the second driver of cost increases. Insurers wrote policies during the soft market of 2019 and 2020 without adjusting for rising claim severity. When nuclear verdicts began hitting in 2021 and 2022, carriers that had been underpriced for years saw renewal premiums jump 30% to 50% in a single cycle.

That whipsaw pricing pushed marginal carriers out of the market entirely. Fleets that could not afford the new premiums either shut down or went uninsured, concentrating risk in the remaining pool. The cycle repeats: fewer insured carriers mean higher premiums for those who remain, which forces more carriers out, which raises premiums again.

Tech-forward solutions as the only exit

Oppenheimer says traditional insurers cannot solve the problem because they lack the data infrastructure to price risk at the driver and trip level. Cover Whale and other insurtech companies use telematics, real-time safety scores, and machine learning to segment fleets by actual performance rather than broad industry averages. That allows them to offer lower premiums to carriers who invest in cameras, lane discipline, and driver training.

For small fleets, the message is clear: insurance costs will not stabilize until underwriters can measure risk in real time. Carriers that adopt telematics and share data with insurers will pay less. Carriers that rely on annual renewals and paper logbooks will pay more or lose coverage entirely.

What this means for brokers and small carriers

The Supreme Court ruling and state-level liability expansion hit brokers and small carriers hardest. Brokers now face direct exposure in crash cases, which raises their insurance costs and makes them more selective about which carriers they book. Small carriers with older equipment, no telematics, or marginal safety scores will find fewer load opportunities as brokers tighten vetting standards to limit their own liability.

Carriers that operate in high-liability states like California, Florida, and Texas will see the steepest premium increases. Fleets that can shift lanes to lower-liability states or invest in safety technology to offset state-level risk will have an advantage. The rest will either pay the premium or leave the market.

The insurance crisis is not a temporary spike. It is a structural shift driven by legislative fragmentation and underwriting failure. Carriers that treat insurance as a compliance checkbox rather than a risk-management tool will not survive the next three years.
