Shippers running freight across the US-Mexico border are running short of trucks at the worst possible time. Mexican commercial drivers are scarce, US visa rules keep qualified operators parked at the border, and nearshoring keeps piling new tonnage onto lanes that can't expand fast enough.

FreightWaves reports the two pressures are landing on the same drayage market, and the math isn't pretty for anyone shipping northbound.

The lane in one number

Roughly $800 billion of goods crosses the US-Mexico border each year, and about 70% of it moves on wheels. Trucks carry the lion's share of northbound auto parts, electronics, medical devices and fresh produce, and haul southbound the steel, plastics and chemicals that feed Mexican maquiladoras. When that fleet wobbles, the whole bilateral supply chain catches a cold.

What's actually breaking

Two pressures are stacking on the same lane: not enough qualified Mexican drivers, and not enough of them cleared to cross.

On the supply side, Mexico's commercial driver pool is shrinking faster than fleets can replace it. Long-haul over-the-road work keeps losing recruits to domestic construction, last-mile delivery and ride-hailing, where hours are saner and home time is real. Driver schools graduate too few candidates, and retention lags turnover on most long-haul fleets.

On the policy side, the United States still has no dedicated visa category for commercial truck drivers. Mexican operators wanting to move freight deep into US territory clear immigration hurdles that are slow, expensive and patchy. The FAST and SENTRI trusted-trader programs help carriers with US-side operations, but they don't solve the upstream problem: a Mexican driver without US credentials can't take a container past the border.

So most cross-border freight moves in drayage. A Mexican driver delivers the container to the port of entry, hands it to a US-domiciled driver, and turns around for the next pickup. That handoff is where capacity lives or dies.

What does it cost drayage?

Drayage has always run on thin margins, and the math gets uglier when border crossings back up. Laredo, Texas handles more northbound trucks than any other US land port, and the queue stretches when US-side trucks run short. Wait times past two hours cost drivers runs, stack detention charges, and force shippers to either pay up or miss delivery windows.

The second-order effect lands on importers. Nearshoring has filled industrial space in Texas, Tennessee and the Mexican Bajío with new automotive, electronics and medical-device inventory. Those goods need trucks to reach distribution centers and assembly plants. A short fleet means slower inventory turns, fewer backhauls and a steeper bill per move.

Carriers on the Mexican side aren't sitting still. Several large fleets have raised driver pay by double-digit percentages over the past two years. Retention is improving but still trails turnover. Until the pipeline fills, every shipped container competes for a smaller pool of qualified drivers.

What does this change for shippers and brokers?

Expect three things this quarter:

• Longer lead times on cross-border lanes
• Firmer drayage rates
• A sharper premium for carriers with US-side assets

Brokers already working with US-domiciled carriers will feel it least. Those leaning on Mexican fleets for first-mile pickup will pay the difference, or accept the delay.

Forwarders sourcing from Mexican maquiladoras should expect tighter appointment windows at Laredo and Otay Mesa, and longer dwell times at US distribution centers when the cross-border handoff slips.

The federal lever sits in Washington. A dedicated trucker visa, or an expansion of the FAST program to cover more commercial drivers, would unlock capacity fast. Without it, nearshoring's gains keep running into the same old wall: not enough trucks, and not enough drivers cleared to drive them.
