fair comment TG. I’d over looked that point 
Krankee:
The quoted example of ‘animals’ is, of course, particularly pertinent. We’d need Denis to input on this but, if carrying Livestock, then one couldn’t exactly find the nearest lay by and then unload the ‘cargo’ into the nearest field.They need food. They need water. They need a secure containment area. Which could still be two or three hours away.
And there are Regulations concerning the movement of Livestock which, I believe, effectively override certain parts of the EU hours Regs.
Sorry, missed this one
EU 1/2005 is the relevant regulation.
without going into too much boring detail - If you are unexpectedly delayed on a journey and stopping would cause welfare problems for the animals then I believe you have to continue to a place where the stock can be safely unloaded and given water and feed.
for standard transporter authorisations this a journey expected to last up to and including 8 hours.
