Which car has the right of way at such an intersection?

The blue car, which has the right of way on the main road, drives first.
The pink car then continues when the road is clear.
The yellow car follows because its turn is the most difficult.
A simple tip to never hesitate again:
Ask yourself these three quick questions at every T-intersection:

Who stays in the main lane? → absolute priority.
Who makes the simplest maneuver?
Who cuts into whose path?
In a few seconds you will have the right answer, even in the most difficult situations.

Since a calm driver is a conscious driver, mastering these little rules will make the road smoother… and much more pleasant for everyone thanks to a well-understood intersection.
