Last updated Apr 6, 2026|Official source

Summary

Requires the Secretary of Transportation to make rules that force motor carriers to have enough financial protection (like insurance or other proof) to pay for injuries, property damage, and environmental cleanup when they move freight between states or between a state and a place outside the United States. The basic minimum is $750,000 for general freight. Moving certain bulk or very dangerous materials must have at least $5,000,000, though that can be lowered to not less than $1,000,000 in U.S. territories if the territory’s leader asks, safety won’t be hurt, and $5,000,000 insurance is not available. Other hazardous shipments must have at least $1,000,000, with possible smaller amounts for some intrastate non-bulk moves and for farm vehicles in non-bulk interstate moves. The Secretary can require private carriers to file proof that meets either the federal minimum or the state-required amount, whichever is higher, and the proof must cover final judgments for injuries, deaths, or property loss. A few defined terms: a farm vehicle is used only for farming and only uses highways incidentally; interstate commerce includes transport between a state and a place outside the U.S. when the trip is in the U.S.; “State” includes the 50 states, D.C., Puerto Rico, the Virgin Islands, American Samoa, Guam, and the Northern Mariana Islands. Proof of financial responsibility may be insurance, a guarantee, a surety bond, or self-insurance. Carriers from neighboring countries must carry proof in the vehicle or be denied U.S. entry. Knowing violations can bring civil fines up to $10,000 per day after notice and hearing, and collected penalties go into the Highway Trust Fund. Vehicles under 10,000 pounds are exempt unless they carry class A or B explosives, poison gas, or large amounts of radioactive material.

(C)operated only incidentally on highways.
(2)“interstate commerce” includes transportation between a place in a State and a place outside the United States, to the extent the transportation is in the United States.
(3)“State” means a State of the United States, the District of Columbia, Puerto Rico, the Virgin Islands, American Samoa, Guam, and the Northern Mariana Islands.
(b)(1)The Secretary of Transportation shall prescribe regulations to require minimum levels of financial responsibility sufficient to satisfy liability amounts established by the Secretary covering public liability, property damage, and environmental restoration for the transportation of property by motor carrier or motor private carrier (as such terms are defined in section 13102 of this title) in the United States between a place in a State and—
(A)a place in another State;
(B)another place in the same State through a place outside of that State; or
(C)a place outside the United States.
(2)The level of financial responsibility established under paragraph (1) of this subsection shall be at least $750,000.
(c)The Secretary may require a motor private carrier (as defined in section 13102) to file with the Secretary the evidence of financial responsibility specified in subsection (b) in an amount not less than the greater of the minimum amount required by this section or the amount required for such motor private carrier to transport property under the laws of the State or States in which the motor private carrier is operating; except that the amount of the financial responsibility must be sufficient to pay not more than the amount of the financial responsibility for each final judgment against the motor private carrier for bodily injury to, or death of, an individual resulting from negligent operation, maintenance, or use of the motor vehicle, or for loss or damage to property, or both.
(d)(1)The Secretary of Transportation shall prescribe regulations to require minimum levels of financial responsibility sufficient to satisfy liability amounts established by the Secretary covering public liability, property damage, and environmental restoration for the transportation by motor vehicle in interstate or intrastate commerce of—
(A)hazardous material (as defined by the Secretary);
(B)oil or hazardous substances (as defined by the Administrator of the Environmental Protection Agency); or
(C)hazardous wastes (as defined by the Administrator).
(2)(A)Except as provided in subparagraph (B) of this paragraph, the level of financial responsibility established under paragraph (1) of this subsection shall be at least $5,000,000 for the transportation—

(i)the chief executive officer of the territory requests the reduction;
(ii)the reduction will prevent a serious disruption in transportation service and will not adversely affect public safety; and
(iii)insurance of $5,000,000 is not readily available.
(3)The level of financial responsibility established under paragraph (1) of this subsection for the transportation of a material, oil, substance, or waste not subject to paragraph (2) of this subsection shall be at least $1,000,000. However, if the Secretary of Transportation finds it will not adversely affect public safety, the Secretary by regulation may reduce the amount for—
(A)a class of vehicles transporting such a material, oil, substance, or waste in intrastate commerce (except in bulk); and
(B)a farm vehicle transporting such a material or substance in interstate commerce (except in bulk).
(e)Regulations prescribed under this section may allow foreign motor carriers and foreign motor private carriers (as those terms are defined in section 10530 of this title) providing transportation of property under a certificate of registration issued under section 10530 to meet the minimum levels of financial responsibility under this section only when those carriers are providing transportation for property in the United States.

(B)a guarantee.

A separate violation occurs for each day the violation continues.
(2)The Secretary of Transportation shall impose the penalty by written notice. In determining the amount of the penalty, the Secretary shall consider—
(A)the nature, circumstances, extent, and gravity of the violation;
(B)with respect to the violator, the degree of culpability, any history of prior violations, the ability to pay, and any effect on the ability to continue doing business; and
(C)other matters that justice requires.
