Still concerned about the possibility trucks could be used for bombings, the FBI also has checked student records at a Colorado truck-driving school, classroom instructor Jack Atencio said. Agents visited the school in Henderson, just northeast of Denver, for a few hours last week, checking specific names, Atencio said. --
FoxNews.com (October 15, 2001) A similar lack of press scrutiny has extended to specialty licenses too, such as the "hazardous material" (hazmat) permits the FBI now believes several dozen suspicious Middle Eastern immigrants sought through a Colorado truck-driving school. According to Time, the men paid cash, and did not use the school's job-placement services — an important aspect of the program's appeal. They also could speak no English, relying on a translator they brought along, yet somehow passed the state's hazmat written exam, which is given only in English. --

And even another article regarding the Colorado Truck Driving School:
THE DENVERCHANNEL.com: "FBI: ARABS DID NOT TRAIN AT COLORADO TRUCK SCHOOL" (ARTICLE SNIPPET: "Only five former students were found to be of Middle Eastern descent, and none of them were suspicious, officials said.
"They paid for their training with student loans. They do speak English, and we find nothing sinister in the training they received, or the subsequent employment they sought and fulfilled," FBI special agent Mark Mershon said.
Though this tip turned out to be false, FBI officials continued to urge residents to report anything suspicious.") (October 15, 2001)
