What should you do when you approach an intersection without traffic controls?

When approaching an intersection without traffic controls, the appropriate action is to yield to vehicles and pedestrians already in the intersection. This is important for maintaining safety and order, especially at locations where no signs or signals dictate right-of-way.

Yielding means allowing others who are already in the intersection to proceed first, which helps prevent accidents that could occur if drivers attempt to assert their right of way in the absence of clear rules. This supportive approach ensures that both vehicles and pedestrians are safe, fostering mutual respect and awareness among all road users.

The other choices present options that compromise safety. Speeding up could lead to dangerous situations, particularly if other vehicles or pedestrians are present. Stopping without proceeding may disrupt the flow of traffic unnecessarily, and turning on hazard lights does not serve a purpose in this context. Therefore, yielding is the best course of action to ensure safety and compliance with the unwritten rules of the road.
