Status of Mexican Trucks in the United States: Frequently Asked Questions

Introduction
In the North American Free Trade Agreement (NAFTA), which took effect in January 1994, the
United States and Mexico agreed to allow each other’s trucks to carry goods across the border to
make deliveries anywhere inside their respective countries. This provision was controversial in
the United States, and a trial program begun in September 2007 by the Bush Administration was
defunded by Congress in March 2009. Mexico imposed tariffs on certain U.S. goods in response
to the program’s termination, as permitted by NAFTA. After bilateral negotiations, the Obama
Administration recently announced a new pilot program to allow long-haul Mexican trucks into
the United States.1
This report answers frequently asked questions regarding the current plan to permit Mexican
trucks into the United States. For more detailed information on the background of this program,
the customs processes at the border, and the economics of cross-border trucking, see CRS Report
RL31738, North American Free Trade Agreement (NAFTA) Implementation: The Future of
Commercial Trucking Across the Mexican Border
, by John Frittelli.2
What Is the Obama Plan?
The Obama Administration’s pilot program would proceed in three stages for Mexican long-haul
trucks. Stage one would begin when the Mexican firm is issued a provisional operating authority
by the U.S. Federal Motor Carrier Safety Administration (FMCSA) after completing a pre-
authorization safety audit.3 This audit, among other things, includes checking a carrier’s records
for driver drug and alcohol testing, hours-of-service compliance, Mexican commercial driver’s
licenses, and ability to obtain U.S. insurance, as well as testing each driver’s English proficiency
and inspecting each vehicle that will be participating in the pilot. During stage one, the Mexican
carrier’s trucks and drivers would be inspected each time they enter the United States for at least
three months. If the carrier does not receive at least three inspections during the initial three
months, stage one would be extended.
FMCSA would evaluate the safety of the carrier during stage one, and after this evaluation is
completed, the carrier could proceed to stage two. In stage two, the carrier’s trucks would be
inspected at the border at the same rate as other Mexican trucks, which are restricted to the border
commercial zone. During stage two, FMCSA would continue to monitor the carrier’s safety
performance. Within 18 months of issuing the provisional operating authority, FMCSA would
conduct a compliance review of the Mexican carrier. If the Mexican carrier receives a satisfactory
rating and has no pending enforcement or safety improvement actions, the carrier would receive
permanent operating authority, beginning stage three after it has operated at least 18 months
under provisional authority. (In calculating the 18 months, carriers that participated in the Bush
Administration pilot program would have that time credited toward their 18 months.) To maintain
permanent authority during stage three, the Mexican carrier must comply with all FMCSA safety
regulations and renew its safety inspection of vehicles every 90 days for the remainder of the

three-year pilot program. When the pilot program concludes, the Mexican carrier could convert
its permanent authority to standard permanent authority similar to that of U.S.-based carriers.
How Does the Obama Plan Differ from the
Bush Program?

Under the Bush program, Mexican trucks did not undergo a “full inspection” (as defined in
regulation), but were “checked” to see whether the carrier had passed a pre-authority safety audit
(by displaying a special decal) and whether the driver had a valid license and was proficient in
English. The Obama Administration’s plan would require, during an initial period of at least three
months, full inspections of all participating long-haul Mexican trucks when they arrive at the
border.
The Bush program anticipated the installation of global positioning system (GPS) devices on
Mexican trucks to monitor their travel in the United States. The Obama plan incorporates not only
GPS devices but also electronic onboard recorders (EOBRs) to enforce driver hours-of-service
limits and to track the trucks’ movement inside the United States.
The Bush program, limited to 100 carriers, would have used crash data to determine the safety of
Mexican long-haul trucks. The Obama plan has no limit on the number of Mexican carriers and
intends to use roadside inspection data rather than crash data to determine the safety of Mexican
trucks. FMCSA calculates that 4,100 inspections over three years among 46 participating
Mexican carriers will be needed to produce sufficient data to validate the results of the pilot.
The other, more numerous, safety requirements for long-haul Mexican trucks in the Obama plan
are items continued from the prior Bush Administration plan.4
Why Grant Mexican Trucks Long-Haul Authority?
In NAFTA, the United States and Mexico agreed to allow each other’s trucks to make deliveries
from Mexico into the United States and vice versa. The intent is to reduce the cost of truck
transportation between the two countries, thereby making trade more efficient. Without long-haul
authority, Mexican trucks are limited to the commercial zone around U.S. border towns and cities.
The commercial zones range from about 3 to 25 miles inside the United States.5 A shipment from
Mexico to a U.S. point beyond the commercial zones must be transferred from a Mexican truck to
a U.S. truck in the vicinity of the border, raising the cost of transportation.

Status of Mexican Trucks in the United States: Frequently Asked Questions

Are U.S. Truckers Interested in Operating in
Mexico?

Before the Bush pilot program, Mexico did not allow U.S. trucks anywhere in Mexico. Under the
Bush pilot program, 10 U.S. carriers participated in Mexico’s reciprocal pilot project. These
carriers operated 55 trucks on 2,245 trips into Mexico.6 Mexico continued to allow these U.S.
trucking firms to operate in Mexico after the United States terminated its pilot program in 2009.
As of April 2011, four of the 10 U.S. carriers were continuing to operate in Mexico.7 Most U.S.
trucking firms offering services in Mexico do so through a partnership with a Mexican trucking
firm.
Where Would Mexican Trucks Travel and
How Many Would There Be?

Relative to rail and coastal shipping, trucking is more costly for long-distance shipments, even
with a driver paid according to Mexican wage scales. Therefore, it is likely that most Mexican
trucks in the pilot program will not travel beyond the border states. The results of the 2007-2009
Bush pilot bear this out. Under that program, Mexican participants made 12,516 trips into the
United States. Of these, 1,439, or 11.5%, were to destinations beyond the commercial zone. Only
4% of these long-haul trips (a total of 80 trips) were to destinations beyond a border state. Almost
all of the trips beyond the border commercial zone were to destinations within Texas and
California. In more than 30 states no Mexican project participant was identified at roadside
inspections during the 18 months of the program.8
The relatively few Mexican trucks hauling goods far beyond the border states would likely be
carrying highly valuable and/or time-sensitive goods. For example, new cars and trucks and auto
parts are significant imports from Mexico. Fresh produce (tomatoes, peppers, cucumbers) is also
a major import from Mexico and is carried in trucks even for long distances because of
refrigeration requirements. Mexican beer is another product that would likely be carried by
truck.9 Electronic equipment, such as televisions, computers, appliances, and cell phones, is
another product with high value-to-weight ratios and thus might be efficiently trucked from
Mexico to distant parts of the United States.10

9 Railroads could carry a larger share of beer compared to produce because beer merely needs protection from
temperature extremes and has a much longer shelf life. Railroads tend to carry harder, less tender produce, such as root
vegetables and apples. Further information on products traded with Mexico, their mode of travel, and U.S. origins and
destinations is available from the U.S. Department of Transportation (DOT), Office of Freight Management and
Operations, Freight Analysis Framework. However, publicly available import data often do not distinguish between the
location of the importer of record (the company’s headquarters) and the actual destination of an import shipment.

Status of Mexican Trucks in the United States: Frequently Asked Questions

It is difficult to predict how distribution patterns might change as a result of the trucking program.
In some cases, sunk investments in warehouses near the border for packaging or transloading
operations could reduce the attractiveness of utilizing Mexican long-haul trucks in the United
States.
In many cases, using a Mexican truck to carry shipments far from the U.S. border will be
economically viable only if the carrier is able to pre-arrange a backhaul load from the United
States to Mexico. Car haulers and refrigerated carriers both use specialized equipment, which
narrows their backhaul market considerably. The United States exports new cars to Mexico, but in
far smaller quantities than it imports (it exports more parts, which would be carried in “dry van”
trailers). Refrigerated carriers prefer finding, if not refrigerated cargo, at least cargo that requires
temperature protection for backhauls.11 While the United States exports meat, dairy, fruit, and
other temperature-sensitive products to Mexico, these products may not be shipped from the
vicinity of destinations for imported produce. Also, produce is imported from Mexico seasonally,
with the peak season from November through January, when fewer U.S. agricultural products
may be available for export to Mexico. The difficulty of arranging backhauls is likely to slow the
expansion of Mexican truckers within the United States.
What About Hauling Domestic Freight in the
United States?

NAFTA does not require that Mexican trucks be allowed to carry U.S. domestic cargo, and the
Obama Administration pilot plan would not allow them to do so.12 As is already the case with
Canadian trucks, Mexican trucks would be allowed to operate in the United States only if they are
carrying cross-border cargo or if they are running empty for the purpose of picking up cross-
border cargo. Mexican trucks would be allowed to pick up a load in the United States and deliver
it to either Mexico or Canada, but they would not be permitted to carry freight from one U.S.
point to another. A corresponding restriction applies to U.S. trucks operating in Canada or
Mexico.
However, an inconsistency in trucking regulations may cause some confusion with respect to
Mexican trucks. In 1999, the U.S. Customs Service (now U.S. Customs and Border Protection)
amended its regulations to allow a foreign motor carrier to make a domestic delivery as long as
that movement is “incidental” to the international delivery. Under this exception, a Mexican or
Canadian truck could carry U.S. domestic freight along the route it would follow to return to its
home country. This change was made purposely to increase the efficiency and utilization of
trucks.13 However, immigration regulations require a foreign national driving a foreign-based
truck to obtain a B-1 visitor visa, which prohibits the holder from engaging in such incidental
domestic movements.14 Thus, it is immigration regulations, rather than trucking regulations, that
require Canadian or Mexican truck drivers to carry only cross-border cargo when operating in the
United States.

Status of Mexican Trucks in the United States: Frequently Asked Questions

Will Allowing Long-Haul Authority Improve
Border Efficiency?

Besides the transfer of cargo between short-haul and long-haul trucking firms, there are other
inefficiencies at the border that are obstacles to reducing the cost of cross-border transportation.
Heightened security concerns have raised the scrutiny of traffic moving in both directions. The
wait time for border crossing can be hours and is highly unpredictable. This requires motor
carriers to pad extra time when dispatching drivers, time that is lost even if the processing time
proves less than expected, as drivers cannot be assigned other loads so quickly. Problems with
incomplete cargo documentation or the need to conduct secondary customs inspections can back
up trucks, even for those enrolled in pre-registered customs programs designed to speed the
clearance process at the customs booth. Complaints persist that customs booths are not staffed
sufficiently at peak periods. Mexico’s customs processing is generally more labor-intensive than
the United States’ processing. Mexican customs brokers, rather than the shippers, are responsible
for the accuracy of shipment information. They may conduct manual piece counts of trucks’
contents for both incoming and outgoing cargo to verify proper payment of duties and taxes. This
occasionally requires trailers to be unloaded and reloaded.15
The long wait time at the border is the reason a third truck is used to shuttle cargo across the
border. Rather than tying up long-haul truck equipment, shuttle trucks are used to move the cargo
through the border-crossing process. These shuttle carriers are usually owner-operators using
older equipment, and are normally hired by Mexican customs brokers or freight forwarders. In the
case of produce trucks, only a driver is hired to move the cargo through the border process (the
truck equipment is not exchanged). The economic rationale for granting long-haul authority is to
allow for use of one truck instead of as many as three for long-haul shipments between Mexico
and the United States. However, border wait times can negate any potential advantage gained by
displacing short-haul equipment with long-haul equipment.
Are Mexican Trucks Less Safe Than U.S. Trucks?
Currently, there are about 4,600 Mexican carriers operating within the commercial zones and
about 1,000 Mexico-based but U.S.-owned carriers that have limited operating authority beyond
the commercial zones.16 Based on the results of roadside truck inspections in the United States
over the last five years, Mexican trucks and drivers have a comparable, if not slightly better,
safety record than U.S. trucks and drivers.17 The long-haul Mexican trucks participating in the
Bush pilot program also demonstrated a superior safety record compared to U.S. trucks, although
the sample size was too small to be statistically significant.18

15 Cargo originating from a maquiladora or shipments between a parent company and its subsidiary may be somewhat
more streamlined.
16 These 1,000 carriers operate under U.S. provisions that were in place before NAFTA. They receive certificates of
registration to operate within specific states beyond the commercial zones.

Status of Mexican Trucks in the United States: Frequently Asked Questions

The safety of trucks may have less to do with whether they are of U.S. or Mexican origin and
more to do with the type of truck. Drayage carriers, trucks that make short-haul movements and
spend much time idling while awaiting customs processing, tend to use older equipment. Long-
haul trucks tend to carry relatively high-value goods or temperature-controlled cargo, because
lower-value goods and less time-sensitive goods can be carried over long distances much more
economically by rail or water. If shippers are willing to pay a substantial premium over rail or
water transport to truck their product long distances, it seems plausible that they would choose a
reliable trucker with modern equipment to avoid risk of delay or spoilage. For instance, since
refrigeration technology is continually improving, shippers expect carriers to have the latest
equipment for temperature and atmospheric control.
The difference in economic incentives for short-haul versus long-haul trucking raises an
important policy issue. If safety is more important to long-haul trucking than it is to short-haul
trucking, limits on cross-border travel by long-haul trucks may increase the presence of older,
less safe trucking equipment in the border zones.19
A congressionally mandated study of the causation of accidents in the United States involving
large trucks that resulted in at least one fatality or injury found that the driver is a more critical
factor than the vehicle.20 The study reported that in 87% of those incidents in which a truck was
determined to be primarily responsible for a crash, the driver was the critical factor, while a
problem with the truck was the critical factor in only about 10% of the cases.
FMCSA has determined that a Mexican commercial driver’s license is equivalent to a U.S.
commercial driver’s license, and that the knowledge and skills testing for obtaining a Mexican
commercial driver’s license is similar to that in the United States. It also found that, unlike the
United States, Mexico requires pre-test training for all new truck drivers, with additional training
prior to each license renewal. FMCSA has access to traffic violation data for violations that occur
in Mexico.21
Which Trucking Groups Are Opposed to
Mexican Trucks?

U.S. truck driver organizations are opposed to allowing Mexican truck drivers to make deliveries
beyond the border commercial zones.
The International Brotherhood of Teamsters is strongly opposed to allowing Mexican trucks to
make long-haul deliveries into the United States. The Teamsters represent less than one in 10
truck drivers in the United States. Most Teamsters in the trucking industry work for UPS.22 The

carhauling market and national less-than-truckload (LTL)23 carriers are two other truck segments
where the Teamsters still have a strong presence. One Teamsters concern is Mexican trucks
delivering cars from Mexican auto plants to U.S. dealers.24 There are about 5,000 Teamster
carhaulers today, down from about 12,000 just a few years ago, and the union’s share of the
carhaul market has fallen below 70% due to increasing competition from non-union carriers as
well as railroads.25 A provision in the master contract between the Teamsters and unionized
carhaul carriers seeks to essentially keep the border closed. This provision states, “Vehicles
destined for delivery via truck transportation from the U.S. to Canada and vice-versa, or from the
U.S. to Mexico and vice-versa, shall be delivered to an agreed terminal or marshaling area, from
which point final delivery of the automotive vehicles shall be made by the drivers in their
respective countries. Present agreed practices shall remain in effect.”26
Many independent owner-operator truck drivers are also opposed to allowing Mexican trucks to
operate in the United States. These small trucking companies typically operate under the federal
operating authority of a larger trucking company, and many find loads through a truck broker.
They typically work in the truckload segment and would face competition from Mexican firms
for NAFTA-related freight, including refrigerated cargoes. Historically, independent owner-
operators were particularly important in hauling produce, which was exempted from federal
economic regulation of trucking under the former Interstate Commerce Commission, and this is a
sector in which Mexican trucking firms seem likely to be active.
