Professional trucking is a lightly [[regulation|regulated]] industry. Most trucking companies police themselves, with the caveat that the federal government requires a certain standard of behavior to be met by each employed trucker. For example, truckers coming into the United States from Mexico must be U.S. citizens, or else have [[green card]]s that allow them to work within the United States of America. Furthermore, they must be fluent in English, which is necessary to understand essential road signs such as traffic lights and speed limits. American truck companies and drivers have opposed increased competition from Mexican trucks and truckers, and have forced cancellation of an experimental program. This has caused diplomatic tension between the U.S. and Mexico. | Professional trucking is a lightly [[regulation|regulated]] industry.
