There are all types of drivers with varying experience levels you can hire. You are able to set parameters like years of experience so you only see drivers who fit your needs.
There are currently hundreds of drivers active on the Relay Network. After placing an order, you will be able to see how many drivers are located in the nearby area at that time.
You as the carrier determine the worker classification as the driver is hired by you and not Relay. You can opt to hire 1099 or W2 drivers on the Relay network based on your needs and work as you see fit.
