The purpose of the three-year pilot program is to demonstrate the impact of Mexican trucks on U.S. highway safety. The law requires the program to include a statistically valid number of trucks. In September, the DOT's inspector general reported only five trucks had entered the program, and only three made trips beyond the border zone.The Teamsters have predicted the program would fail. The suit claims the Federal Motor Carrier Safety Administration breaks the following laws:
- It waives a law that trucks must display certain proof that they meet federal vehicle safety standards.
- It breaks the law requiring the pilot program to achieve an equivalent level of safety because Mexican drivers don't have to meet the same physical requirements as U.S. drivers.
- It breaks the law that Mexico must provide simultaneous and comparable access to U.S. trucks. Mexico cannot do so because of the limited availability of ultra-low sulfur diesel fuel in Mexico.
- It breaks the law that the pilot program must include enough participants to be statistically valid.
- It doesn't comply with the environment requirement of the National Environmental Policy Act.
