We have one roundabout in the town that I live in. It’s a foreign concept to me, but it’s nice to be acquainted with new things. One thing I’ve noticed is that every time I use the roundabout, I never use a turn signal. This violates the central precept that I live by when driving:
Always use a turn signal.
People who do not use turn signals are one of the worst people in the world. So why aren’t I doing it? There’s hardly any time. I enter the roundabout, I pass the first turn and I’m right there. If I did it before that first roundabout, I might cause an accident and if I do it after, I’m already in the middle of turning so I’m not signalling anything.
Signals should be to signal what you’re going to do not what you’re already doing.
But let’s see what a quick Google search comes up with:
For continuing straight ahead, do not signal on approach and signal “right” before you leave.
Use right turn signal when passing the exit before the one to be taken
Look for pedestrians and use your turn signal before you exit, and make sure to stay in your lane as you navigate the roundabout.
Clearly, my assumptions were wrong and I know the answer for the future.
