Certain logistics companies have been pushing drivers into "owner-operator" scenarios, where they are responsible for gas, insurance, maintenance, and lease payments, while not being given the flexibility to drive for other companies. Leaving some drivers with negative paychecks (basically, their pay didn't cover expenses).
I'm betting they are going after 18 years olds specifically because they are kind of primed to into debt for a career because the college admissions process kind of primes them to think this is normal.
