Similar to the reason you signal at a 4 way when turning across traffic (in that case it prevents a deadlock of two non indicating idiots waiting for each other when if they both indicated they could both go simultaneously).
In the roundabout case it lets drivers know you’re exiting the roundabout and they can enter it. It makes traffic much more efficient but it does need to be enforced since it’s for the benefit of other drivers not yourself.
- CamperBob2 2y agoTrusting the other driver's turn signal at a 4-way stop is fine. Trusting the other driver's turn signal when one or both is in motion is a good way to get killed. Signaling to enter or exit a roundabout communicates no useful information.
- mk67 2y agoVery nonsensical statement, as it helps a lot since decades and allows faster traffic flow in roundabouts.
- CamperBob2 2y agoHow does it allow faster traffic flow? You haven't been driving long (or at all) if you think trusting other drivers' turn signals is a good idea. Theories that look good through a bus window often don't work as well when viewed through a windshield.
