More years ago than I care to disclose I worked for a custom combining crew in the USA. AS the harvest moved from south to north we moved from farm to farm by loading the combines on truck beds. One of the first lessons we ":greenhorns" received was to know the height of our load and to read the signs on overpasses informing the maximum height a load could be. If the load was just a little too high we let air out of the tires, if it was more than letting the air out would allow us to drive under the overpass we had to take an alternate route.
The driver of this load should have practiced by hauling combines in the USA.😉
