Problems getting on track after joining server

[Curtis1]

Solution found: Turn spectate off in options

I did a quick search and was not able to find a solution so I ask here instead.

I can get into a server and see others practicing but when I push the drive button in the bottom right, it won't let me join. No matter what server I join the same results. Any idea why this is happening? What can I do to resolve this issue?

Thanks in advance for any assistance provided.
