Truckers have recently been the target of scams seemingly coming from the US DOT. The persons behind the fraud might induce a trucker to release banking information. Please pass this warning along to your clients - the US DOT is NOT asking for releases to banking information. You can go to the US DOT OIG website for more information.
The US DOT and FMCSA warn "Advise your local carriers and law enforcement agencies if you are targeted by this scam and be suspicious when asked for banking information from anyone".
