TMR put this up on their Facebook asking who has to give way, but that's too easy. A much more complicated question is: what does the law say around indicating?
I've seen people say only blue must indicate, others say both must indicate, and yet others say neither must indicate. Which is correct?
@Zagorath
Transport Operations (Road Use Management—Road Rules) Regulation 2009 QLD
Section 149
Giving way when lines of traffic merge into a single line of traffic
A driver in a line of traffic that is merging with 1 or more lines of traffic travelling in the same direction as the driver must give way to a vehicle in another line of traffic if any part of the vehicle is ahead of the driver’s vehicle.
Maximum penalty—20 penalty units.
What's a penalty unit?
@observes_depths
This financial year it is $161.30
They say "penalty unit" so that each time they increase the fine amount, they only have to update the legislation in one place - the place where the value of a penalty unit is defined. Otherwise, every time the fine amount changes, they would have to recalculate all the penalties and update the legislation in hundreds of places with a new dollar amount.
