I have a Class B CDL and work for a national company. I drive class B trucks and pickups w/trailers for work. I may only drive the Class B truck, 5 or 6 times in a year for a week at a time. The same goes for the pickup and trailer. I was told we have to fill out a drivers log for every day we work, off day, and vacation. Does this apply to occasional drivers? Or do I fill out a log book for 7 days prior, and when I'm driving?
