Final answer:
The right of way at a 4-way stop is typically given to the vehicle on the right, with special considerations if one vehicle is going straight and another is turning left. Observance of traffic signals and speed limits is critical for safety, and drivers must yield to emergency vehicles by stopping.
Step-by-step explanation:
When cars arrive at a 4-way stop at the same time, the right of way is typically determined by a few simple rules. The most common rule is that the vehicle to the right has the priority to proceed first. If one car is on the right of the other, that car has the right of way. In the case where one vehicle is going straight and the other is turning left, the car going straight has the priority. If all four cars arrive at the same time, gestures, or a common understanding to proceed in a clockwise direction may resolve the situation.
It is crucial for drivers to observe traffic signals and signs to ensure road safety. Things like speed limits and pedestrian crossings are designed to protect all road users, including drivers and pedestrians. In the event of seeing an emergency vehicle such as an ambulance, the appropriate action would be to stop and become stationary, allowing it to pass safely. Understanding and following these rules ensures that everyone stays safe and traffic can flow smoothly.
