Combining two jobs

Hi all I hope that someone can help me to get my head around the regulations regarding my job circumstances. I work a permanent night shift in a factory, I do Sunday, Monday and Tuesday nights 6pm until 6am for a month then I do Wednesday, Thursday and Friday nights 6pm until 6am for a month I would like to know how many hours I can legally drive on this shift pattern. When I finish on the Sunday, Monday , Tuesday I get until the following Wednesday off but when I finish the Wednesday Thursday Friday I go back in on the Sunday again which means I work 6 out of 7 nights. This sounds complicated but my week is usually 36hrs with no driving. I passed my class1 in May and I am trying to get some part time work to gain experience. Any help would be appreciated.

You can effectively do 12 hours for someone driving. You need to average 48 hours and keep to weekly rest periods etc.

It may be different due to you shift pattern and because a driving week is from 00.01 Monday morning so some weeks you may be able to work another day. It gets very complicated!

I used to work mon- fri and could only work every other sat to keep in line with weekly rest.

Thanks for the reply
