Why am I not able to use the Co-Driver feature?
If you have a co-driver on your logs and then you guys move trucks for whatever reason, the Drive Safe HOS Black Screen with Green Numbers will not show up when driving is detected. If the Co-Driver does not log into the vehicle prior to the first driver driving, you will not be able to access the Co-Driver's log. "Co-Driver(s) Info missing - try again later" message will show up when you press the Co-Driver button.
