You as the carrier determine the worker classification as the driver is hired by you and not Relay. You can opt to use 1099 or W2 drivers on the Relay network based on your needs and work.
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.
Drivers work for you as a carrier. Relay can provide options for Worker's Compensation and/or Occupational Accident Insurance for the drivers you use on the Network if you need it.
