Generally, truckies just talk to each other on UHF40 (or 29) to arrange safe overtaking.
But a turn signal has always been a warning signal. It points to where one should never be.
It's not uncommon, though, for a truck that has *already* executed an overtaking manoeuvre to 'thank' the vehicle now behind them with an R-L-R-L combo of single flashes, *after* they're back on the correct side of the road.
Some truckies add a 'flourish' of one or two 'hazard light' flashes to the end of the sequence.
But, in all my years on the roads, I've only heard of recently deceased idiots who've tried overtaking a truck that has had its right-hand indicator on.
Things may have changed in the last decade, but FIIK why!

Yes, but Social Media apps can derive location data through other means, including time zone and language settings, visible WiFi Access Points, not to mention GPS.
The Libs passed the legislation because they're corrupt.
Labor passed it because they're incompetent.
Either way, it's likely that the AustGov will be the gatekeepers of 'onboarding' and re-verification of existing users.
It's a disgrace.
