How should drivers behave at a four-way stop according to the CR-3 Traffic Code?

At a four-way stop, the proper action for drivers is to come to a complete stop and yield the right of way to vehicles that arrived before them. This ensures order and safety at intersections where multiple vehicles may approach from different directions.

When drivers stop completely, they can better assess which vehicle has the right of way based on the established rules for such intersections. The general rule is that the first vehicle to stop is the first to go when it is safe to do so. In cases where two vehicles arrive at the same time, the vehicle on the right has the right of way.

The other options do not align with the established protocol for four-way stops. Proceeding at once would lead to chaos and potential collisions, as there is no outlet for determining who should move first. Yielding to pedestrians only does not account for the need to manage vehicular traffic. Finally, signaling is important for indicating turns but does not address the responsibility to stop and yield at the stop sign itself.
