First when you spawn(at newbie spawn),use /gps so you can locate place where you can start driving test.
When you arrive to red checkpoint,you can press enter or F or you can use command /enter.
When you come in,you should go in the little classroom and use command /driverlic.
Then you will be TPed in vehicle for which is used for driver test.
Also you will have some rules and you have to follow them,if you do not follow them you will fail.
1. You should not drive any faster than 115km/h.
2. Do not damage the vehicle.
3. You need to take less than 90 seconds per checkpoint to pass.
At the end if you followed all rules,you will pass it.
Congratulations!
