Honestly, no I don't. I do not drive for Celadon but even if I did I still couldn't answer the question. You need to talk with a recruiter or someone with hiring authority. Even current drivers for Celadon might give you inaccurate info because policies change all the time.

Id call Celadon but from what i saw above you should be okay. I have a friend driving for them and she likes it.
You're going to have to tell a recruiter anyway if you fill out an app so just call and ask them tomorrow before you spend the time filling out an online application.
