How difficult is the adr test for hazardous substances drivers?
Answers:
not difficult at all providing you are only doing the standard groups and don't need explosives or atomic.
I doubt they add all that much apart from safety, which would be mostly common sense
it depends on which groups you wish to aquire!
Did mine in the army it took a bit of study but if you put the effort in and you really want to pass you should fly through the test.
Good luck
