Final answer:
At an uncontrolled intersection or a four-way-stop, the car on the right should proceed first if both arrive at the same time. This rule helps maintain traffic flow and safety.
Step-by-step explanation:
When arriving at an uncontrolled intersection or four-way-stop at the same time as another car, the general rule of the road is that the car on the right should proceed first. This means, if two cars arrive at an intersection at the same time, the car to the right has the right-of-way. If you are the driver on the left, you should yield to the car on your right. This rule ensures that there is order and safety on the roads and prevents confusion and accidents. It is important to follow these rules consistently to maintain traffic flow and safety.
The idea of the car with the 'loudest horn' proceeding first is incorrect and does not comply with traffic laws. Traffic laws serve to create a predictable environment where all road users can understand each other's intentions and act accordingly.
