Hi All!
As I'm driving around the main Hwys and Fwys in Australia I often notice that one a truck overtakes another truck they will flash their Left indicator once (to signal they are moving to the left lane again) flash their right hand indicator once (and this is my interest) then put their left hand indicator on as normal and change lanes...
I have noticed a few variations, but its obvious it not just an accident as they move across, so I'm wondering if anyone can tell me what it means (is it a thankyou, a "salute to fellow road traveller or something else) and/or the etymology of this gesture...
Cheers,
Bock
