What is the preference rule at intersections without signs?

At intersections without signs, the general preference rule is that the vehicle on your right has the right of way. This rule is grounded in the principle of yielding to traffic that is already present in the intersection or to vehicles that approach from the right. It helps ensure a smooth flow of traffic and reduces the risk of accidents by providing clear guidance on who should yield.

This approach is particularly important in situations where there are no traffic signals or signage to dictate who should go first, thus relying on a simple and widely understood convention to manage right-of-way. Knowing this rule helps drivers navigate these intersections safely and effectively, as it encourages predictable behavior among road users.

The other options would not typically apply in this context. For instance, vehicles on your left do not automatically have preference or precedence, and all vehicles must stop is an inaccurate interpretation since stopping is generally only required when necessary for safety. Pedestrian right of way is also crucial, but is more relevant in designated pedestrian crossings rather than in intersections that lack signage.
