Regardless of whether the load was strapped properly or not, one of the reasons that DVSA are cracking down on loads not being secured properly is because of the needless hours and £millions lost because of delays purely due to having to clear up loads after something like this which wouldn’t have necessarily needed to be had they been secured properly.
No idea how many of you watch Highway Thru Hell but there’s been plenty of times they’ve come to a vehicle on its side down an embankment and the load is still in place because it has been secured properly, often not moving at all especially if it is timber.
