You don't. Sorry, bikes DO NOT make left turns in intersections. You go straight across, then cross from there. I've biked to school and work for 25 years, and in intersections, I never make a left turn. It takes 2 minutes extra at the most, small price to pay for not being under a truck.
Smaller roads, sure, if there's no traffic, you just look over your left shoulder and make the turn if it's all clear.
I took a bike safety class that was supposedly taught by professionals and supposedly based on local vehicle legislation (in California) and they taught us to make vehicular left turns, by positioning ourselves in the rightmost traffic lane which is allowed to turn left, and indicating our intentions to make a left turn with our hands. I've subsequently done this several hundred times in various kinds of traffic.
Did they make a mistake? Is this not consistent with what motorists are being taught to expect? Are motorists commonly not being taught what to expect, and getting confused about this?
All the replies here seem very strange for me as in the UK at least, the highway code says that we are entitled to be in the middle of the lane if we need to be, and actually turning right (read as left turn for US / EU people), we're supposed to be in the centre of the correct lane for that manoeuvre.
There are always some idiot drivers who think that bikes have no right to be on the road, and who'll pass dangerously close to you, sound their horn as they're passing a few inches away from you (and the distraction could easily make you swerve into them), complain if you take the middle of the lane, but open their doors in front of you if you stay on the edge, etc. On the whole though, drivers in the UK tend to be careful when cyclists are around, and I've never had any aggression from someone when I've been in the second or third lane to make a right turn.
As a cyclist, I also find it incredibly irritating when another cyclist runs a red light, not only because it reflects badly on the other cyclists, but also they'll probably be in my way a minute later, when I need to pull out further in the road to overtake them, as it's almost always the slowest cyclists who won't stop for a red light.
For California, I don't know. For western European: Oh my god YES!
By all mean signal which way you're going to turn, but in intersection, especially those with multiple lanes, you never make a left turn. Drivers will not expect you in the middle of the intersection.
> don't know. For western European: Oh my god YES!
You are over generalising. I don't know where you are but where I am in western europe cyclist absolutely cross intersections like a vehicle.
The trick is to take control of the lane. If you are sticking to the side cars won't see you. If you take up space in front of them they will see you and include you in their calculations.
And before you or someone else jumps here to spread some fud: No i am not advocating jumping in front of cars with zero warning. Or whatever silly idea you have based on what I just wrote. I see this done all the time, and I do it fairly regularly.
You have to be seen. You have to be predictable. You have to know where you are heading.
For Eastern European: bikers can turn left at intersections, they must signal with their arm, position themselves to the left of the lane just as cars do, and drivers have to expect them. It’s being taught in driving schools, for heaven’s sake.
But just as you don’t signal and start your left turn in your car at the last moment, so you don’t with a bike. Unfortunately, we have bikers who go to a left turn from the rightmost position, don’t signal or signal when it’s useless. The rule for drivers is to expect and anticipate stupid people and not kill them.
This is really not correct. I'd say in the most of Europe, you signal left, you take the entire lane and make your turn on the intersection. In many places there are even dedicated zones in front of left lanes (taking the entire width), so that it's obvious cyclists have the right to do so.
And the same thing on roundabouts, if you want to safely ride a roundabout you absolutely have to take the entire lane and not allow cars to overtake you. Otherwise cars exiting the roundabout will run over you.
I don't know what parts of western Europe you're talking about, but in Germany, cyclists absolutely make left turns all the time. Also, drivers are taught about this in driving school, so they will (or should at least) expect cyclists to be there.
For the record, I personally prefer crossing twice as well. But I'll disagree with "western Europe".
The GP is plainly wrong. ~Everyone in Switzerland does normal vehicular left turns, and the bicycle exam for schoolchildren includes making vehicular left turns correctly (i.e. signaling, waiting for cars that are in process of overtaking you, moving to the middle of the road, possibly stopping, turning when the way's free of vehicles that have right of way).
I don't think California drivers see enough cyclists do the same thing to have any kind of consistent expectation of what cyclists will do, or what they should do.
Smaller roads, sure, if there's no traffic, you just look over your left shoulder and make the turn if it's all clear.
