3. Pre-Authority Safety Audit (PASA)
• Review carrier’s safety management programs (vehicle maintenance, drug and alcohol testing programs, driver qualification files, etc.).
• Review driving records for only those drivers who would participate in cross-border long haul operations.
• Review the combined driving record of drivers who would participate in the program (U.S. driving history, Mexican Federal license history, and Mexican State license history).
• Inspection of each vehicle to be used in the phased in program.
• Check all participating vehicles for Federal Motor Vehicle Safety Standards (FMVSS) certification.
• Check all participating vehicles for EPA emissions standards.
• Conduct an English Language Proficiency and US Traffic Laws knowledge test of each driver participating in the program, conducted in English.
