The article says 80% but it's surely wrong, you say, it's more than 20%. Why would the ministry of transport people make that up? I'm not surprised, as rig accidents are on the rise - often, too many hours and defective eqpt - not the drivers' faults, as employers or contractors are very demanding. Ever looked at those big trucks and their tires, for example, when they stop at a stop light? Often just plain horrifying.<quoted text>
Sorry, 80% does not sound real to me. Maybe 20% but not 80%. This was some years ago but I had a trailer with the old lug-piloted wheels and one wheel had three of the ten fasteners sheared off on the inside. This is something a trucker driver would not normally notice during his daily inspection.
Oh, you are allowed 10% of brakes/ wheel fasteners to be defective and still be road worthy. That is why most heavy trucker have wheels with ten lugs. If nine are good, you can still roll.
Same with ten sets of brakes on an eighteen wheeler. You can have one brake out of service and still be legal to roll.
I was buying a set of steering tires at a truck stop on a Sunday afternoon and they sheered one stud off. The local Freightliner dealer was closed but the Kenworth was open and they had the part. It would have been legal to roll with one broken but I would not be as happy.
The inspectors talked of defective trucks, did not mention percentages.
