A log binder with paper log sheets may come in handy in situations when a pro driver needs to record hours of service manually instead of using an ELD when operating a CMV. Although uncommon there are certain times when you may not need to use an electronic logging device (for instance if your EDL fails or when a log isnt needed more than 8 days in a 30-day period - always check the most recent regulations regarding exemptions). This binder can keep a loose-leaf log book organized and protected and has pockets to store pens and other important paperwork to help keep your organized while over the road. This log sheet holder zips so nothing falls out and nothing creeps in.
