My enquiry was prompted by an observation in a book that suggested that tiredness was a factor and that tiredness was caused by restrictions on driver's hours not being robustly observed. However, that seems to be refuted by the replies in this thread which I accept.
Driving in Iraq is not a routine task - it is virtually an act of war in itself. As mentioned above, speed can sometimes be seen as a force protection measure in its own right - there is a balance between the risk of an RTA and that of an IED.
In addition to the insurgency threat, I believe there are probably few other countries in the world where you are regularly likely to encounter an HGV travelling at night, without any lights, the wrong way up a 6 lane highway.
Drivers hours legislation is effectively a peace time diktat. That said, it is MoD policy to comply wherever possible. Commanders take this very seriously but operational needs will come first, and an element of risk management may be required.
There are plenty more non-fatal RTAs than those that get reported and the reasons behind all of these are carefully analysed and appropriate advice promulgated to reduce recurrence. In fact, there is a Warrant Officer at 2* HQ level (the Force Master Driver) who's sole task is pretty well to minimise RTAs.
In terms of barking up trees (or indeed climbing on bandwagons, if I may mix cliches), your contribution could hardly have been seen as supportive of British soldiers really, could it?
In any case, I hope we have now clarified matters.
