Ride on rightmost lane that goes straight or right yield to drivers?

At least in Austria and Germany the only situation where you can be required to drive on the left is when taking a left turn. (e.g. Austrian STVO: § 12. Einordnen)

Per default you have to drive as far right as is reasonable.

That being said, if it doesn’t endanger or inconvenience you, it doesn’t hurt to accommodate other driver’s needs.

I do this regularly biking in the US. Taking the lane at an intersection reduces many dangers at intersections. If there was a car in the lane that was going straight the cars behind would also not be able to turn right on red. At the light, you are moving at exactly the same speed as a stopped car going straight and so there is really no reason for you to not use the same amount of space.

I am not a lawyer and the exact laws around biking vary between states in the US so this is not legal advice. Though for reference my state would require me to ride "as far to the right as is safe/reasonable" so I believe that my suggestions follow this.

Also as an aside, cars turning right on red is really dangerous and shouldn't be a normal thing.
