100% idiot !! i have worked driving trucks / reccovery trucks
what may look firmly or feel firmly tied down is a falacy !!
i have had to stop on a motorway hard shoulder to re strap down a car on a reccovery truck that started off firmly strapped down but had slackened off through flexation of the reccovery truck bed and slight movement of load
bear in mind that was a solid load bed and purpose made ratchet load straps
that load is on a coka cola tin roof with string !!
pity the person that gets decapitated on the curb by a wing because someone was too tight to pay for correct transport !!
legal isn’t always safe !!
safety is a difrent matter , i wouldn’t have done it !! and say the worst nightmare happened it would be very doubtful you would be insured !!
