I am surprised that the antics of the drivers (and perhaps the owners too) of heavy vehicles, that is, lorries, tippers, bulk concrete carriers, container prime movers and trailers and coaches, do not seem to catch sufficient attention of the authorities.

Drive along any expressway or major multi-lane road during off-peak hours and you will find heavy vehicles keeping pace with you at 80kmh to 90kmh - or worse still, tailgating you. Stand on a pedestrian overhead bridge over one of these roads for 10 minutes and you don't have to be a rocket scientist to gauge that most of these heavy vehicles are racing beyond their vehicle speed limit.

By the way, heavy vehicles are supposed to be fitted with speed limit devices. What we see on the road suggests widespread tampering with these devices between vehicle inspections.

Heavy vehicles may form a small part of the total vehicle population. But their bulk and greater carrying capacity mean accidents involving them tend to be more serious and damaging.

The authorities are correctly concentrating their enforcement efforts on drink driving. Keep up the good work. But please take a closer look at the misdemeanours of goods vehicle and coach drivers. For too long they seem to be winning this cat-and-mouse game.
