Why do some stopped buses use indicators, and some use hazard lights?
It’s long been a bugbear of mine that a vehicle that has correctly stopped in a legal parking/stopping position should not use its hazard lights.
Some buses do this, despite being stopped in proper bus zones. Melbourne Bus Link appears to be one company whose buses mostly do this. Most buses from other operators seem to just use their left indicator.
I reckon this is not only pointless, it actually causes problems when the bus driver wants to pull out.
Motorists are obliged by law to give way as a bus pulls out from the kerb, but the change from “hazard lights on” to “indicating right” is pretty much indistinguishable, because the motorist would have to be checking the bus’s left indicator and notice it stop flashing.
It also can cause problems if the bus driver forgets to turn off the hazard lights, and the bus continues down the road with them flashing.
Yes, the bus in the video above isn’t entirely within its lane — it looks like the lane simply isn’t wide enough. But the use of hazards happens everywhere with some bus companies. I don’t think it makes much sense in most cases.
