That's profiling.
I'm thinking its probably not illegal to profile a truck. That's all an officer needs. Does the DOT need probable cause to pull over a CMV? Thinking not. Otherwise there wouldn't be such thing as a "random inspection".
Now, that said, if an officer starts a roadside "random" then all bets are off and he could probably opt to inspect everything except the driver's shoe size.
Assuming that I understand what "randoms" are all about.
