Researching Hgv Driving, What are expected working hours?

If youre doing "length of the country runs" thatll be nights out too. Start 05hr00 Monday finish 16hr00 Friday, maybe Saturday morn sometimes. Shop deliveries maybe 07hr00 to 16hr00 daily?
Road transport is a very varied beast.

Edit to add. Be careful when discussing working hours and pay etc.
You may start work at 05hr00, and finish at 20hr00. Other folk may say youve done 15hrs work, but you wont always get paid that. Depending on contracts, breaks, POA etc, you may be paid through you may not. Many of that days hours may be paid, but not count towards WTD hours, even discussing hours gets many of us talking at cross purposes.
