Talk to the regular driver or see the report to see what other cover drivers do on that route. If it is a split route you won't get much info on it. Not much you can do really, except file over 9.5 grievences. Make sure to take your full lunch and break, do not use this time to sort truck or deliver. If you aren't getting to drive much, then just do your job as best you can and cash that check with a big fat smile on your face.
