Medical Courier Insurance: The Houston Vetting Checklist

Medical courier insurance is the part of vendor selection that gets a checkbox and thirty seconds of attention. A certificate of insurance arrives as a PDF, someone confirms it exists, and the file closes. That is a reasonable process for a landscaping vendor. It is a poor one for a company whose drivers walk your loading dock every morning, carry irreplaceable specimens, and operate vehicles on the Southwest Freeway in your name.

The gap is not that Houston facilities ask the wrong questions. It is that the legal floor in Texas sits so much lower than most procurement teams assume that a courier can be fully compliant with state law and still leave your organization holding a claim. Here is what the floor actually is, and what to require above it.

The Texas Auto Liability Floor Is $30,000

Every driver in Texas has to carry liability coverage, and the required amount is smaller than a single ambulance ride. Per the Texas Department of Insurance auto insurance guide, state law requires at least $30,000 of coverage for injuries per person, up to $60,000 per accident, and $25,000 for property damage — the combination written as 30/60/25.

That is the number behind a legally insured vehicle. It is not a number that survives a multi-vehicle collision on I-45 during the afternoon build, and it is not a number any hospital's risk office would accept if it were stated plainly instead of buried in a certificate.

There is a second problem underneath the first. A personal auto policy generally does not cover the work at all. TDI's own guide lists, among the things most policies do not cover, accidents that happen while you are driving for a ride-hailing service or delivering items for a fee, and accidents that happen while driving for business. A courier running routes on a personal policy is not underinsured. In a claim, the courier may be uninsured for that trip entirely — and the facility that dispatched the run gets named anyway.

Most Medical Courier Vans Are Not Federally Regulated

Facilities often assume a courier is backstopped by federal trucking rules. For the typical medical courier fleet, it is not. Under 49 CFR §390.5, a commercial motor vehicle is one with a gross vehicle weight rating of 10,001 pounds or more — or one carrying placardable quantities of hazardous materials, or designed to carry more than eight passengers for compensation.

A Transit Connect, a Sienna, or a sedan running specimens between a Katy clinic and a Medical Center reference lab clears none of those thresholds. The federal minimum financial responsibility rules do not reach it either.

The contrast is the useful part. 49 CFR §387.9 sets $750,000 as the floor for a regulated freight carrier hauling ordinary nonhazardous property. A vehicle carrying blood tubes, a transplant-adjacent tissue block, or a short-dated infusion dose is exempt from that floor purely because of its weight. The commodity is more consequential and the coverage requirement is lower. Nothing fills that gap except your contract.

The Texas Workers' Compensation Gap

This is the exposure Houston facilities miss most often, and it is specific to Texas. The Texas Department of Insurance states plainly that in Texas, private employers can choose to carry workers' compensation insurance coverage, but it is not required in most cases. Employers who opt out are called non-subscribers.

“In Texas, private employers can choose to carry workers' compensation insurance coverage, but it is not required in most cases.”

— Texas Department of Insurance, employer guidance on workers' compensation

This is not a theoretical minority. Per TDI's 2024 biennial report on the Texas workers' compensation system, the non-subscription rate that year was the lowest since 2016 — and it was still 24 percent of employers, covering 13 percent of Texas employees.

Roughly one Texas employer in four has no workers' compensation coverage. Small owner-operated courier companies sit squarely in the segment where that is most common. When a driver for a non-subscriber is injured, the injury does not resolve inside a comp system — it resolves through litigation, and the property owner where the injury happened is an obvious defendant.

How This Lands on a Houston Loading Dock

Picture an ordinary Tuesday at a Houston-area reference lab. A courier driver arrives for a 6:40 a.m. pickup, comes through a receiving bay that was mopped twenty minutes earlier, and falls carrying a rack of tubes. The specimens are lost. The driver has a fractured wrist and eleven weeks off.

1. If the courier is a workers' compensation subscriber, the injury runs through that system and the lab's exposure is limited to an ordinary premises question.
2. If the courier is a non-subscriber, there is no comp claim to run. The driver's path to recovery is a negligence suit, and the wet floor in your receiving bay is the fact pattern.
3. The lost specimens are a separate question entirely — general liability typically will not cover damage to property in the courier's care, custody, and control. That is what cargo coverage is for, and cargo limits on small courier policies are frequently set at a few thousand dollars.
4. If the driver was a subcontractor rather than an employee, the courier may argue it is not the employer at all, which changes who your contract can actually reach.

None of those four branches involve anyone behaving badly. They are the ordinary consequences of a coverage structure nobody read before the first pickup — which is why insurance verification belongs in the same conversation as service levels and delivery windows, not in a separate procurement appendix.

The Five Things to Verify Before You Sign

• Commercial auto liability — a business auto policy, not a personal one, at a limit your risk office would defend in writing. Confirm hired and non-owned auto coverage if any driver uses a personal vehicle.
• Commercial general liability — covering bodily injury and property damage arising from operations on your premises, with your organization added as an additional insured by endorsement rather than by a line of text on a certificate.
• Cargo or inland marine coverage — sized against what a single run actually carries. Ask for the per-shipment limit in dollars and compare it to the replacement cost of a full rack of specimens or a temperature-controlled pharmacy load.
• Workers' compensation — and if the courier is a non-subscriber, say so on the record and require an occupational injury plan plus a defense and indemnity clause that survives the answer.
• Driver employment status — employees or independent contractors, in writing. Subcontracted drivers can be entirely reasonable, but the coverage, background-check, and training obligations have to follow them, and the contract has to say so.

Why the Cheapest Bid Is Often the Uninsured One

Coverage is a real cost, and it is one of the few costs a courier can remove without the client noticing on day one. Commercial auto instead of personal, cargo limits sized to medical freight instead of parcels, and workers' compensation in a state that does not require it are three line items that separate a per-stop rate more than route efficiency does.

That is worth remembering when comparing courier pricing across bids, or when weighing a courier against running deliveries in-house — where the same coverages become your own payroll and fleet obligations rather than someone else's. A quote that is meaningfully below the field is usually explained by something, and coverage is the most common something.

Key Takeaway

Texas sets a low bar and lets vendors stand on it. A courier can carry the state-minimum 30/60/25, decline workers' compensation like roughly a quarter of Texas employers, subcontract its drivers, and still be entirely legal. Your contract is the only instrument that raises that floor. Ask for the policy type and not just the limit, verify additional-insured status through the endorsement, price cargo coverage against what a single run is worth, and get driver employment status in writing before the first pickup rather than after the first claim.
