If your commercial truck insurance renewal came back higher again this year, you are not being singled out. Commercial auto is the one line of business that has kept rising while almost everything else in the commercial insurance market has softened. Here is what is actually driving your premium in Texas, which parts of it you control, and which parts you do not.
Is commercial auto insurance really going up, or does it just feel that way?
It is going up, and it has been going up for a very long time. Industry survey data reported through trade press this spring put commercial auto premiums up about 5.8% in the first quarter of 2026 — the highest of any commercial line, and the 59th consecutive quarter of increases. In the same period, overall property and casualty premiums fell 1.2%, the first market-wide decline since 2017.
Read those two numbers together and you get the whole story of 2026: property is cheap again, liability is not, and commercial auto is the most stubborn liability line on the board. A fleet owner who hears “the insurance market is softening” and then opens a renewal with a 9% increase is not confused. They are just in the wrong line of business for good news.
There is also a hard, Texas-specific data point on the table. The Texas Department of Insurance approved rate changes for the Texas Automobile Insurance Plan Association (TAIPA), the state’s assigned-risk plan, in Commissioner’s Order No. 2026-9983. Per Bulletin B-0005-26, commercial automobile rates rise 4.9% overall effective November 1, 2026, for new and renewal business — with bodily injury and property damage liability each up 5.0%.
TAIPA is the market of last resort, not the voluntary market, so this is not a statewide 4.9% mandate. But it matters for two reasons. It is a regulator-reviewed signal that Texas commercial auto losses justify more rate. And if your fleet is at risk of being non-renewed into the assigned-risk plan, that is the number you will be paying against after November 1.
Why is commercial auto the outlier?
1. The federal liability minimum has not moved since 1985
Under 49 CFR §387.9, an interstate for-hire carrier hauling non-hazardous freight in a vehicle over 10,000 pounds must carry $750,000 in public liability coverage. That schedule column is literally headed “January 1, 1985.” It has never been raised. Hazmat operations carry higher minimums of $1 million or $5 million depending on the commodity.
Nobody in the industry treats $750,000 as a real limit anymore. Shippers and brokers routinely require $1 million, and freight contracts increasingly want excess layers on top. The gap between the legal floor and the commercial reality is where a lot of your premium lives — you are not buying the federal minimum, you are buying whatever your customers demand.
2. Verdicts, not accidents, set the price
Here is where we will be more careful than most of what you will read online. There are a lot of “median nuclear verdict” figures floating around the trucking press right now, ranging from roughly $22 million to over $50 million, and they trace back to competing vendor blog posts rather than to a single verifiable dataset. We are not going to quote a number we cannot source.
What is verifiable is that Texas lawmakers considered the problem serious enough to legislate on it. House Bill 19, passed by the 87th Legislature and effective September 1, 2021, is captioned “Relating to civil liability of a commercial motor vehicle owner or operator, including the effect that changes to that liability have on commercial automobile insurance.” The statute created a bifurcated trial structure so that a plaintiff must first establish the driver’s negligence before putting the carrier’s hiring, training, and supervision practices in front of a jury.
HB 19 helped. It did not end the problem. Severity keeps climbing even where frequency is flat, and severity is what reinsurers price off of.
3. Repair and medical costs compound quietly
A tractor with advanced driver assistance, radar sensors, and a camera package costs meaningfully more to put back on the road after a moderate collision than the same truck did five years ago. Physical damage rates follow. On the liability side, medical cost inflation and long-tail claim development mean a claim opened in 2023 is still developing today — and carriers price 2027 policies off of what those old claims eventually settle for, not what they were reserved at.
What actually moves your number?
You cannot change the federal minimum or the litigation environment. You can change almost everything an underwriter looks at first.
Your CSA and SMS scores
FMCSA’s Safety Measurement System is the first thing most commercial auto underwriters open, often before they look at your loss runs. Unsafe Driving and Hours-of-Service Compliance carry the most weight. A cluster of roadside violations in the last 24 months will cost you more at renewal than a single moderate claim will. Pull your own SMS profile, and challenge inaccurate violations through DataQs — carriers cannot un-see a score, but they can see a corrected one.
Driver qualification files
49 CFR Part 391 sets what has to be in the file. Underwriters read them as a proxy for how the whole operation is run. Missing MVRs, stale annual reviews, and no documented road test on a new hire tell a story that has nothing to do with paperwork and everything to do with whether you are hiring carefully. Minimum experience standards — two years CDL, three years clean MVR — written down and actually enforced, are worth real money.
Telematics and cameras
ELD data is compliance. Telematics and forward-facing cameras are underwriting leverage. Hard-braking and following-distance data lets you show improvement instead of asserting it, and dashcam footage has ended more disputed-liability claims than any argument a defense attorney ever made. If you already run cameras, make sure your submission says so in writing — it does not help you if it never leaves your office.
Deductible and retention structure
Once a fleet gets past roughly 10 to 15 power units and has a decent loss history, taking a higher physical damage deductible or a modest liability retention often buys back more premium than shopping the account does. The trade is real cash flow risk, so it should be a deliberate decision, not a last-minute one.
Renewal timing and submission quality
A complete submission 60 to 90 days out gets underwritten. A rushed one 10 days out gets rated defensively. If your renewal falls near November 1, 2026, and you are anywhere close to the assigned-risk market, start early enough that TAIPA is a fallback rather than a destination.
What if your renewal is up and the number is already bad?
Ask your agent for three specific things: the loss ratio the carrier is using, the individual claims driving it, and which of those are still open reserves rather than paid dollars. Open reserves are estimates. Estimates on stale claims can often be pushed down, and a reserve reduction on a three-year-old file can change a renewal more than a market search will.
Then compare the quote structurally, not just on price. Radius, commodity classification, hired and non-owned exposure, and how many drivers are actually scheduled all change the number. A cheaper policy that classifies your operation wrong is not cheaper; it is a coverage dispute you have not had yet.
