Used to happen a lot when DoT and the Police had the roadworthy blitzs' on long weekends at places like the S Bends south of Gerro, Eneabba, Waroona etc and would set up checkpoints and inspect virtually every 4X, V8 Commy and Ricer... stock family sedans etc would get waved thru.
I got checked every Easter for about 4 years running thru 2010 ish era esp at S bends 'cause the Gerro Feds were crazy hard on 4X's.
They were esp feral on oversize tyres, tyres outside guards, big lifts, Rod Holders/Driving Lights above Bull Bars and seat belts that didn't retract on 4X's
Doesn't happen as much these days due (I guess) to manpower etc
