Borderlands Mexico is a weekly rundown of developments in United States-Mexico cross-border trucking and trade.

Trucker protest raises stakes in Mexico-US B-1 visa dispute

Trucking industry leaders in Mexico are stepping up calls for U.S. officials to clarify how B-1 visa rules are being enforced against cross-border truck drivers, warning that continued uncertainty could disrupt freight flows between Mexico and the United States. The stakes are significant: Mexico is the United States' largest trading partner, with hundreds of billions of dollars in bilateral goods trade moving by truck each year, making cross-border trucking capacity a linchpin of North American supply chains.

Officials with Mexico's National Chamber of Freight Transportation (CANACAR) say Mexican drivers are losing their visas after encounters with U.S. officials involving alleged cabotage violations, yet carriers still lack clear information about how eligibility and violations are determined at different border crossings.

The dispute spilled into public view Thursday when truck drivers blocked commercial traffic at the Mexicali, Mexico-Calexico East (California) border crossing in protest of visa revocations. CANACAR officials in neighboring Tijuana have urged drivers there not to stage similar blockades, warning that shutting down additional border crossings would increase the economic impact.

Alfonso Millán Chávez, CANACAR delegate for Tijuana, Tecate and Playas de Rosarito, said the organization and other business groups are seeking meetings with U.S. and Mexican officials to establish clearer protocols governing visa revocations tied to alleged cabotage, Uniradio Informa México reported.

Millán said disagreements can arise over what constitutes a prohibited domestic movement in the U.S., including how officials treat the movement of empty trailers.

"Sometimes we have had problems with the interpretation, for example with an empty trailer," Millán said, according to El Sol de Tijuana. "The empty trailer is there to be loaded with merchandise, and some officers interpret the empty trailer as merchandise."

Cabotage generally refers to transportation between two points within the same country by a foreign carrier. Mexican truck drivers using B-1 visas are permitted to haul international freight into and out of the U.S., but generally cannot perform point-to-point domestic U.S. freight movements. In Mexico, cabotage by foreign carriers is similarly restricted, a long-standing point of friction in bilateral trucking negotiations dating back to the North American Free Trade Agreement era and the subsequent U.S.-Mexico-Canada Agreement.

Millán said CANACAR wants U.S. authorities to establish protocols for visa actions involving suspected cabotage and to provide reliable statistics showing how many drivers have lost their visas.

CANACAR estimates that more than 25,000 visas have been revoked from commercial drivers along Mexico's northern border, including potentially 4,000 in the Tijuana area. The figures are CANACAR estimates based on reports from its members and social media rather than official U.S. government statistics. The organization has sought information from the U.S. Embassy in Mexico and the U.S. State Department.

Pressure intensified Thursday when truckers protested at the Mexicali commercial port of entry over what drivers described as an increase in B-1 visa revocations. Millán said CANACAR had anticipated growing frustration among drivers.

"We understand the desperation of the drivers, and as a chamber and as an industry, I think we have been anticipating this over the last few months," Millán said. "There hasn't been a week when we haven't raised the issue with various authorities in both Mexico and the United States."

CANACAR is nevertheless urging drivers to pursue negotiations rather than expand the demonstrations to Tijuana.

Millán called for Mexico's Interior Ministry and Ministry of Foreign Affairs to intervene with U.S. authorities, saying the dispute ultimately requires a binational solution. He said CANACAR has already raised the issue with the U.S. Embassy and State Department.

"My hope is that it does not extend to Tijuana," Millán said of the protests. "The idea is that we be cautious with this issue."

He added that CANACAR has consistently favored dialogue over actions that interrupt cross-border commerce.

Ismael Reyes de la Rosa, a CANACAR official in Mexicali, has also raised concerns about how U.S. officers are handling B-1 visas at the border, as drivers seek greater clarity over what activities could trigger cancellation or revocation.

The growing concern is not limited to Baja California. Israel Delgado, CANACAR's vice president for Mexico's northwest region, has warned that visa losses could affect time-sensitive shipments including medical products, technology, food and perishables moving from Mexico into the U.S.

The visa dispute is beginning to ripple beyond trucking companies. José Luis Contreras Valenzuela, president of the Association of Industrialists of Mesa de Otay, said the situation has contributed to delays in incoming supplies and deliveries of finished products. Federico Serrano Bañuelos, president of Index Zona Costa, said companies that outsource transportation services are particularly exposed. Business groups are seeking to elevate the issue to Mexico's Ministry of Foreign Affairs for diplomatic discussions with U.S. officials, according to El Sol de Tijuana.

The dispute comes as cross-border freight activity in the Tijuana region is already below previous peaks. Millán recently said roughly 3,000 export trucks are crossing daily, compared with as many as 4,500 during stronger periods. He said freight volumes fell nearly 30% in 2025 before improving somewhat this year.

Millán said English-language proficiency enforcement, another recent concern for Mexican drivers operating in the U.S., has become less of an immediate problem locally. He said CANACAR had not recently received reports of drivers being placed out of service for English proficiency violations.

"The current challenge is the revocation of visas for cabotage issues," Millán said, adding that such violations are sometimes interpreted "in a very drastic way."

Mexican trucking companies depend on B-1 drivers to move international freight across the border, and industry leaders warn that unclear or inconsistent enforcement of cabotage rules could reduce available cross-border capacity and trigger additional protests at major commercial gateways. Whether the requested binational talks produce clearer protocols, and whether protests spread beyond Mexicali, are the key developments to watch in the coming weeks.

CBP announces extended-hours program for empty trailers at Laredo bridge

Port of Laredo, in coordination with Nuevo León's Border Zone Development Corporation, will begin a 90-day program extending weekday operating hours for empty tractors and trailers at the Colombia-Solidarity Bridge beginning Monday, Sept. 14, 2026, U.S. Customs and Border Protection said.

Laredo is consistently among the busiest U.S. ports for truck freight with Mexico, which makes congestion management there a bellwether for broader cross-border flow efficiency.

Under the program, weekday operations for empty trucks and trailers will begin one hour earlier, at 7 a.m., and continue until midnight, Monday through Friday. Current weekday operating hours are 8 a.m. to midnight.

The program is intended to alleviate morning northbound traffic congestion from Colombia, Nuevo León, to Laredo, Texas. The 90-day timeframe suggests the results will be evaluated before any decision on making the change permanent, giving carriers and shippers a pilot period to gauge its effect on crossing times.

Program details:

• Effective date: Monday, Sept. 14
• Duration: 90 days
• Current weekday hours: Monday-Friday, 8 a.m.-midnight
• Revised weekday hours: Monday-Friday, 7 a.m.-midnight
• Applicable traffic: Empty tractors and trailers only
