I don't have any experience and I've only been driving well expediting for going 6 months now so I don't think I'd make the cut
My new co driver has been on the truck for one month, he is going to WG class next week. It really isn't as prestigious as some make it out to be. Higher paying loads with higher expectations of securement, appearance, and professionalism.
It's really just common sense.
KS6, WG is a marketing term used by FedEx. And maybe some others. White Glove treatment of your valuable items.
Another carrier may call it something else. Just special protocols,carrier specific, no one place to get training.
If my Father held a WG class it'd be 2 minutes long.
1) look good and be very professional to the customer.
2) handle and secure the stuff like it's yours.
3) get back to work. Class dismissed.
