Why $750,000 Was Never Meant To Be Your Limit

A number Congress picked in 1980

Every interstate carrier hauling general freight files proof of at least $750,000 in public liability coverage. Ask where that figure came from and almost nobody can say. It is not an actuarial estimate of what a bad crash costs, and it never was.

Congress set it in the Motor Carrier Act of 1980, Public Law 96-296, signed July 1 of that year. Section 30 of that act fixed the property carrying minimum at $750,000, with $1 million and $5 million for the hazardous materials categories. Carriers did not even have to meet it immediately. Congress allowed a phase in at $500,000 for general commodities while the newly deregulated industry adjusted. Open 49 CFR 387.9 today and the schedule of limits still runs under one column heading, January 1, 1985, with the same $750,000 sitting in the first row.

It was written as an entry test, not a damages estimate

The reason that number has aged the way it has is that it was never built to measure harm. Deregulation was opening the industry to thousands of new carriers, and the House report accompanying the act described financial responsibility as inextricably bound to the entry provisions concerning whether a carrier is fit to operate in interstate commerce. The stated purpose was to create additional incentives to maintain and operate trucks safely and to assure carriers held an appropriate level of financial responsibility.

That is a licensing standard. 49 CFR 387.7(a) says no motor carrier shall operate a motor vehicle until it has obtained and has in effect the minimum levels set out in 387.9. Nothing in either section ties the figure to what a courtroom will award. Your commercial auto liability limit is the number doing the actual work, and the filing only proves you cleared the floor.

The government measured the gap and published it

This is not an insurance industry talking point. Section 32104 of MAP-21, Public Law 112-141, directed DOT to examine whether the minimums were still appropriate. FMCSA delivered that report to Congress in April 2014, built on a study by DOT's Volpe center.

The findings were blunt. Catastrophic crashes, meaning those with damages exceeding the current minimums, were rare at under one percent, roughly 3,300 out of about 330,000 commercial vehicle crashes a year. But severe and critical injury crashes produced damages above $1 million on their own. And the floor had quietly eroded. Had $750,000 simply tracked core CPI from 1985, it would have stood at $1,623,771 by 2013. Indexed to medical CPI it would have been $3,188,250. Over those 29 years medical care inflation ran 4.9 percent annually against 2.8 percent for the core index.

The fix was proposed, then withdrawn

FMCSA followed its report with an advance notice of proposed rulemaking published November 28, 2014 at 79 FR 70839, announcing it was considering an increase. On June 5, 2017 the agency withdrew that notice. Its stated reason was that it lacked sufficient data or information to support further rulemaking, because commenters had not supplied cost or benefit data and the agency could not obtain adequate information on industry liability limits, premium costs, claim frequency, or amounts paid above policy limits.

Congress keeps returning to it anyway. Land Line reported in April 2026 on HR 8218, the Fair Compensation for Truck Crash Victims Act, which would raise the minimum to $5 million. Like the earlier attempts going back to 2019, it has not passed. The floor on your filing today is still the one written in 1980.

What that leaves a small fleet holding

A one truck operation carrying the federal minimum is compliant. Compliant and protected are different words. Our piece on how a nuclear verdict reaches a small truck carrier walks through the mechanism, and the short version is that an award is sized to the harm done, not to the size of the company that did it. A single severe injury crash can pass $750,000 without ever becoming a headline case.

The practical answer is the layer sitting above the filing. Primary liability satisfies 387.9 and keeps your authority alive. An excess or umbrella layer is the part of the program that actually responds to a number somebody else chooses. At one to five trucks you have no fleet average to absorb a bad year, which is exactly why that second layer matters more to you than to a hundred truck carrier. The same logic runs through what commercial truck insurance actually costs, and it is worth reading next to the verdict exposure breakdown before your next renewal.

Price the layer before you need it

Excess limits are easiest to add at renewal, when nothing is pending and your loss runs are clean.
