What are the Working Hours & Overtime specifically for the Fuel transport / Trucking industry
I want to go into diesel/ petrol tankers and normally i have seen that drivers work 3 weeks in and 1 week off in a month

But, not sure what the exact / legal working hours are in that industry as the drivers will definetely have to do lots of KM driving and mostly one can not cover the distances in ordinarly 8 hour shift.
For example, JHB to Durban and back (there is shortage of fuel inland and it has to be loaded from Durban and sent up to JHB)
