Why do trucks carry higher insurance limits, and how much coverage is there?

The minimums, and why they exist

Texas lets a passenger car onto the road with thirty thousand dollars of injury coverage per person; federal law will not let a general-freight interstate carrier move without at least three quarters of a million, and hazardous cargo pushes the required financial responsibility into the millions. The gap is not bureaucratic generosity, it is actuarial honesty: a loaded tractor-trailer at highway speed produces injuries that a car-sized policy could not begin to touch, and Congress decided decades ago that the industry, not the victims, would carry that risk. Many purely intrastate Texas carriers operate under state minimums commonly set at half a million for heavier vehicles, still an order of magnitude beyond the car next to them.

The coverage above the minimums

The legal floor is where the inquiry starts, not where it ends. Reputable fleets, and every carrier a broker or shipper of consequence will hire, stack coverage in towers: a primary policy at or above the federal minimum, then layers of excess and umbrella coverage that can run into the tens of millions, sometimes with the carrier's parent, the trailer's owner, the freight broker, or the shipper contributing policies of their own. There is also a peculiar federal creature worth knowing exists: the MCS-90 endorsement, a public-protection promise attached to the carrier's filing that can require an insurer to pay a judgment even where ordinary coverage defenses might have applied, with the insurer left to chase its own insured afterward. None of this coverage introduces itself. It is found through statutory disclosures, discovery, and the corporate mapping described on the liability page, which is why the empty apology that there is only the minimum policy should be verified, never believed.

What the money means for how the case is built

Coverage shapes strategy. Where a car case may hit a hard policy ceiling, a truck case can support, and therefore demands, the full workup: reconstruction, human factors, the regulatory violations, the life care plan, the economist, because the recovery is not artificially capped by a thin policy at the first layer. It also explains defense behavior, the rapid-response teams at the scene within hours, the early recorded-statement pressure, the quick modest offer, all of it sized to the exposure the carrier's own insurance tower represents. The counter is symmetrical preparation, beginning with the preservation letter and the coverage demand in week one.

Before any number is discussed

No truck case should be valued, much less settled, before every policy in the tower is identified in writing. Silver Key Law treats coverage discovery as a first-month deliverable in every commercial vehicle case, and the consultation is free.
