OK thanks, so I work Monday to Friday 8:30 till 16:30 with 30 mins lunch.
So presumably I can only work about 8 hours every other weekend. The government just love to keep the working man down!!
What makes you think that you can only work an 8 hour driving shift every other weekend 
If you are thinking about the 48 hour week then that does not affect you as 37.5 hours are in a non driving job under the normal WTD which can be fully opted out of leaving only the driving WTD to be considered
