They already know that you likely will be clueless 
Just use what you learned in school on the driving part..
It’s actually required for any company to give a driving test to a new employee..even if you drove for 50 years.
That’s really all they are doing, checking a box for the government..that and figuring out how much help you will need and who to place you with for training.
Good luck, don’t sweat the small stuff.
