Passing A Left Turning Vehicle


Question : This is a (possibly stupid) question about indicating, but I cannot find a definitive answer. It’s about passing a left turning vehicle.

To indicate or not to indicate?

At a lot of intersections, a single lane become two or more lanes, so passing the left turning car on the right would require a lane change.

I would recommend always indicating for this.

However, on some less busy roads it remains a single lane. But, it’s still wide enough to still have room to pass on the right.

For example, when there is a stopped car waiting to make a left turn in front of you.


I indicate to the right to let the driver behind know that I’m about to veer right to pass the left turner. Do you think it’s necessary?

Sometimes I think it might just cause confusion too, as they might think I want to make a right turn?

First of all there is no such thing as a stupid question.

Signals When Passing a left turning vehicle

Second, YES (…in my opinion…) I think this is necessary to indicate.

Remember the reason we signal is to tell others what we plan to do.

The driver behind you probably isn’t psychic.

And probably doesn’t know if you are planning to also turn left, stop and wait patiently for the car to turn left, or turn right, or go around.

Shoulder Checks

Always do a quick signal before you move (not at the same time) in this situation to indicate you’re going around.

Also, you should do a quick mirror and shoulder check. Just like any other lane change, there may also be bikes or other road users in your blind spot.

Even on a road with only one lane in your direction, you can go around a left-turning vehicles; as long as there isn’t a car already stopped behind it waiting.

Treat this simply as any other lane change.

The only thing possibly making this not an official lane change (2 lane changes actually) is the absence of the little white lines on the ground.

So, do a mirror/signal/shoulder check before you go around. And, do another mirror/signal/shoulder check before you go back into the normal lane.

This is to make sure no vehicle behind you has moved into your blind spot.

In addition, this shoulder check helps you notice the left-turning vehicle, if suddenly it has decided it is tired of waiting.

Sometimes this happens & the car seems randomly now continuing straight on. Of course, this is not recommended behavior, but it could happen right?

You are correct in that you don’t want to have the people around you think you’re actually turning right when you aren’t. This could lead to all kinds of other disasters. 

So just make the signal early enough and quick enough and turn off the signal before an opposing left-turner would be confused by it.

Realize too, that the left-turner in front of you is now blocking the view for the potential left-turner facing you.

So, go through the intersection with caution.

Slowly may be a good idea in many cases, especially when there is a considerable gap of space in front of you.

This space may lead the oncoming left-turner to assume there may be nothing coming anymore i.e. a good time for a T-bone collision.
