Who knew?

After seeing numerous heavy vehicles overtake us as we cruised at 100km an hour, I commented some time ago that it seemed that trucks were no longer speed limited to 100kph. Not quite sure why that happened originally or how long ago - perhaps a spate of truck-related accidents? - but it, and the trucks that sped past us, seemed to be long gone. But, not so apparently. A report by the Auditor-General suggests that current speed camera technology does not allow differentiation between trucks and smaller vehicles - so as long as trucks are under the general road limit eg 110kph, they will not be "caught". The good news - for truck drivers? - is that "we have the technology ... but aren't using it".
