Aye, one local company I spoke to yesterday said the same thing. Said I would need to find someone to verify my on duty hours at school, use those hours to update my logs every weekend before I start driving, just in case of an audit. May just wait till summer for the 2nd driving gig, just find a non-dot part time gig for weekends during the school year.
If you are under a DOT consortium, the second company can put you in a truck without a Pre-Employment. Don't know about the random pool. Would assume "yes" if it is a CDL gig.
From If an employee performs safety-sensitive functions for two different employers, is the employee If an employee performs safety-sensitive functions for two different employers, is the employee subject to each of the employer’s DOT drug and alcohol testing programs. Yes, under 49 CFR § 382.305 question 8, the driver must be in DOT random for each employer they are employed with.
Well this is a different issue, if one works for a non-dot company, and then works for a dot company, all hours worked applies to the dot company hours of service. What I mean is if you work ten hours at company X doing say cutting lawns, then go to company Y and you are driving a truck, company X hours apply to company Y logs as work. Now if anyone doesn't think this right or legal, they are wrong. Some time ago there was a case where a FedEx freight driver was moonlighting at a place as a food stock boy. He worked 8 hours at the food place and then went to work at FedEx for 10 hours. One night he got into an accident - fell asleep and ran into a motor home on the freeway in the middle of the night. The state investigators and NTSB pulled his logs as part of the investigation but also in talking to the guy who mentioned he didn't work at his other job that day, but did other things. So they had pulled his employment records from that other job and concluded it was an HOS violation and this opened the door up for one hell of a lawsuit from the people who he hit. I think there was a $20M settlement with FedEx. He was also sued but he ended up settling for the loss of his license for life per agreement with the lawyers as a sacrifice.
It would have still been noticed. I'd be surprised if tax records being pulled is not sop when investigating a wreck involving one who has to log hos. Be it a truck driver, train operator, pilot, etc.
