Excess Liability Coverage: What Texas Truckers Keep Underbuying

Your primary liability policy meets the FMCSA minimum. You filed your MCS-90. You're legal. That's not the same as being protected.

Texas courts have handed down nuclear verdicts against trucking companies for years. A single serious accident on I-10 west of Houston, one fatality, one aggressive plaintiff's attorney, and a $1 million primary limit is gone before the depositions are finished. What comes next hits your assets, your business, and your future loads.

Excess liability coverage exists for exactly that scenario. Most small fleets and owner-operators either skip it, underbuy it, or misunderstand what it actually does. Here's what you need to know.

Excess Liability Mistakes That Cost Texas Truckers Money

Assuming the FMCSA Minimum Is Enough

The federal minimum for most general freight carriers is $750,000. Hazmat carriers go higher. That number was set decades ago and has not kept pace with jury awards or medical costs.

In Texas, verdicts involving commercial truck accidents routinely exceed $1 million. Serious injury cases, especially those involving traumatic brain injury, spinal damage, or wrongful death, can reach $5 million, $10 million, or beyond. If your primary policy pays its limit and the judgment is larger, the remainder comes from you.

Excess liability kicks in above your primary limit. It does not replace your primary policy. It sits on top of it, and it pays after the primary is exhausted. Without it, your business absorbs whatever gap remains.

Buying Too Little Excess Coverage Because the Premium Feels High

Excess coverage is often more affordable than operators expect, especially when compared to what it protects. Buying a $1 million primary and then stopping there leaves a meaningful exposure gap. Stepping up to $2 million or $4 million total via an excess layer is frequently a fraction of the primary cost.

The math matters here. Do not skip excess because the premium quote feels uncomfortable. Get the full picture. The cost of being underinsured after a serious accident is not a number you recover from.

Confusing Excess Liability with Umbrella Coverage

These terms get used interchangeably. They are not the same thing.

Excess liability follows the exact terms and conditions of your underlying primary policy. It pays more of the same coverage. An umbrella policy, on the other hand, may broaden coverage in certain ways and can sit above multiple underlying policies.

For most owner-operators and small Texas fleets, a commercial excess liability policy tied to your primary auto liability is the cleaner, more straightforward option. Ask specifically which product is being quoted and what it follows. If your agent cannot explain the difference clearly, that is a problem.

Not Updating Excess Limits When Adding Trucks or Drivers

You started with two trucks. You added three more over the past year. Your primary policy got updated. Your excess layer did not.

An excess policy that was sized for a two-truck operation does not automatically scale when your fleet grows. More trucks on the road means more exposure, more miles, more risk. Review your excess limits any time your fleet changes in size or operation type.

What Excess Liability Actually Covers (and What It Doesn't)

Excess liability covers the same losses your primary liability covers, once those limits are exhausted. That typically includes bodily injury to third parties and property damage caused by your vehicle during a covered operation.

What it does not cover:

• Cargo claims (that's motor truck cargo coverage)
• Damage to your own truck (that's physical damage)
• Losses that your primary policy excludes entirely (the excess follows the primary, so if primary excludes it, excess excludes it too)
• Non-trucking or personal use claims if your primary does not cover those situations

This last point matters for lease-on operators. If your primary policy excludes certain operations and an accident happens during one of those periods, your excess carrier will deny the claim for the same reason your primary carrier did. The policy language in your primary directly shapes what your excess will pay.

Why Texas Specifically Demands More Coverage

Texas is a high-litigation state. Plaintiff's attorneys here are experienced, aggressive, and well-funded. They know how to present trucking accidents to juries, and Texas juries have shown a willingness to award large verdicts when they believe a carrier was negligent.

Consider a dry van haul on I-10 through the Katy corridor, one of the most congested freight lanes in the country. Thousands of commercial trucks move through that stretch daily. Rush-hour backups, distracted drivers, sudden stops. The exposure is real and constant. A rear-end collision at speed with multiple civilian vehicles can generate claims from several injured parties simultaneously. Each claim draws against the same primary limit.

The Port of Houston area adds another layer of complexity. Container freight movement around the port means more truck traffic, more turns, more congestion, more opportunity for accidents in densely populated zones. A single incident near the port can involve property damage, injuries, and infrastructure claims that stack quickly.

DFW freight lanes carry similar risk. High volume, interstate interchange points, aggressive traffic, and significant population density mean that any serious accident has the potential to generate damages well above a standard primary limit.

Texas also does not cap most personal injury damages in the way some states do. That matters when a case goes to trial.

How TB Insurance Group Approaches Excess Liability

We look at your total exposure before recommending limits. That means understanding what you haul, where you operate, how many trucks you run, and what your primary policy actually says.

A reefer operator moving temperature-sensitive pharmaceutical loads out of the Houston Medical Center does not carry the same risk profile as a flatbed running construction steel on US-290. The right excess limit depends on your specific operation, not a number pulled from a general guideline.

With 25-plus carrier relationships, we can place excess coverage that matches your primary policy correctly and does not create gaps between the two layers. We have seen too many operators show up after an incident with an excess policy that was mis-structured relative to their primary, and the carrier used that to dispute coverage. That is a preventable problem.

We also review your coverage when your operation changes. Fleet growth, new commodities, new lanes, new drivers. Any of those can shift your exposure profile enough to warrant revisiting your excess limits.

Get a Coverage Review

If you are running under $1 million in primary liability with no excess layer, or if you have not looked at your excess limits since adding trucks, schedule a review with TB Insurance Group. We will look at your current policy structure, identify where your exposure exceeds your coverage, and give you a clear picture of what a properly structured excess layer would cost.

No generic quotes. No pressure. Just an honest look at where you stand.
