A Mexican carrier, Servicio de Transporte International y Local SA de CV, is applying to be the 11th fleet to join the cross-border program.

If it is granted authority it would be the largest operation in the Federal Motor Carrier Safety Administration’s pilot program.

Servicio de Transport would bring 13 drivers and 20 vehicles to the program. Most of the 10 carriers that already have authority run just one truck and one driver. None runs more than six trucks or four drivers.

The application, which is posted in today’s Federal Register, is open for public comment through May 13.

It says that Servicio de Transport is related to a new U.S. carrier, International Transportation Services.

The addition of these trucks and drivers would boost FMCSA toward its goal of 4,100 inspections over three years. That’s the target the agency says it needs to hit in order to prove that its cross-border regulatory regime can successfully maintain safety.

The most recent data on the agency’s website shows 934 inspections so far, with the 10 carriers in the program.

Besides Servicio de Transport, four other Mexican carriers have applications pending.
