Final answer:
At an uncontrolled intersection, the general rule is to yield to the driver on the right to prevent accidents and ensure orderly traffic flow.
Step-by-step explanation:
When two cars enter an uncontrolled intersection at the same time, the general rule is that they should yield to the driver on the right. This rule is in place to prevent confusion and potential accidents by providing a clear guideline on who has the right of way in such situations. It's important to note that this rule applies to uncontrolled intersections, which are intersections without traffic signals or signs. Each driver must observe the rule to ensure safety and prevent collisions.
