Good question, probably means you click your tongue
Speaking of links, today we had an incident with one of those hired drivers. He had forgotten to lock the fifth-wheel coupling, so the 'kingpin' was'nt holding on to the wheel. He did'nt bother testing it or anything like that, he just assumed that it would lock on it's own, so he raised the support legs, hooked up power, ABS, air and drove off... for about ten metres before the trailer dropped off, shattering the lights on the link and made my day a living hell.
The only way to get the trailer back up was either with a forklift, wich we don't have, or by manually raising the support legs. Guess who drew the short straw?
Oh yeah. Me.
Good fun!
