How long can you stay awake ? Some courier / parcel firms send 5-6 vans up to Carnryan every night because they don’t have to keep record or use a tacho . When you see these guys day in day out with their eyes hanging out of their sockets you realise van driving is not for anyone long term . Not surprising that most of the off road accidents on the A75 are vans forgetting to turn the corners at the end of long straights .
