Do U.S. trucks need Mexican insurance to cross the border?

Article 63 Bis of the Ley de Caminos, Puentes y Autotransporte Federal says all vehicles that travel on federal roads and bridges must have insurance guaranteeing third parties for damage to their property and persons caused by operating the vehicle, and that buying it is the vehicle owner's responsibility. The Finance Ministry sets the minimum coverage. The article was added in 2013, and the consolidated text published by Mexico's Chamber of Deputies shows a last reform in November 2025.

Operating a U.S. truck inside Mexico also raises Mexican permitting and customs questions that are beyond an insurance page. Work with your customs broker and a provider that writes coverage for Mexico.

Every auto policy has a coverage territory clause. Read yours. If it does not list Mexico, the policy does not respond to a crash there, including your liability, physical damage, and cargo. Some policies extend limited coverage near the border; do not assume, confirm it in writing.

Going the other direction, Mexican-domiciled carriers operating in U.S. border commercial zones must meet U.S. financial responsibility rules. Under 49 CFR 387.7(b)(3), they can buy coverage for periods of 24 hours or longer and must carry an MCS-90 and an insurance document showing the coverage dates in the vehicle. That is their requirement, not yours, but it explains why interchange partners at Laredo or El Paso carry different paperwork.

Most Texas cross-border freight changes hands near the bridge. If a Mexican carrier or drayage company pulls your trailer, or you pull theirs, the trailer interchange agreement and your cargo form's territory and transfer conditions matter more than Mexican auto insurance.
