Under multi-manning, the ‘second’ driver in a crew may not necessarily be the same driver from the duration of the first driver’s shift but could in principle be any number of drivers as long as the conditions are met. Whether these second drivers could claim the multi-manning concession in these circumstances would depend on their other duties. On a multi-manning operation the first 45 minutes of a period of availability will be considered to be a break, so long as the co-driver does no work.
