ROG:
Start 0600 both do different things till 0700 which is allowed for the first hour only - after that both drivers must stay together
Not necessarily. One driver could have several second drivers during the period but then really only driver 1 could work to double manning rules. It doesn’t have to be the same pair of drivers for the entire journey but if one driver is working more than 15 hours and claiming double man rules then he must be accompanied for all but the first hour of his shift.
For example.
Drivers 1 and 2 start work at 06:00 Driver 1 is a Southerner and Driver 2 a Northerner.
06:00 - 06:30 Other Work
Leave Southern Depot
06:30 - 11:00 Driver 2 drives, Driver 1 on break.
11:00 - 11:05 swapping cards
11:05 - 15:00 Driver 1 drives, Driver 2 on break.
Arrive Northern Depot
Driver 2 clocks off and goes home. Shift of just over 9 hours - Single manned rules.
Driver 3 joins Driver 1, Driver 3 is a Southerner.
Swap trailers
15:30 Depart Northern depot
15:30 - 19:30 Driver 3 drives, Driver 1 on break
19:30 -19:35, swapping cards
19:35 - 23:35 Driver 1 drives, Driver 3 on break
Arrive back at Southern Depot, roads were quieter so southbound journey was a little quicker than the northbound.
00:00 Both Drivers clock off and go home
Driver 3 shift of 9 hours - Single manned rules
Driver 1 shift of 18 hours - Double manned rules.
All 3 drivers legal.
