At a four-way intersection, which vehicle may proceed first?

• A. The vehicle turning left
• B. The vehicle going straight
• C. The vehicle turning right
• D. All vehicles may proceed at once

Answer: (B)

In a four-way intersection, the vehicle going straight typically has the right of way, particularly when traffic signals are not present, or when vehicles are approaching from different directions. This rule is designed to facilitate a safe and orderly flow of traffic.

When multiple vehicles arrive at the intersection simultaneously, the general rule applies that vehicles going straight can proceed first unless they are facing a yield or stop sign. Other vehicles, such as those turning left or right, must yield to the straight-moving traffic to avoid conflicts and possible collisions. This is consistent with traffic laws that prioritize straightforward movement, which reduces uncertainty and improves safety at intersections.

While the vehicle turning right is allowed to proceed, it must do so only after confirming that the lane is clear and that no vehicles going straight are present. Hence, even if turning right may seem like an immediate option, it must yield to straight-going vehicles.

In summary, the correct answer identifies the vehicle going straight as having priority, thereby promoting safe navigation through the intersection.
