Final answer:
The right of way at intersections is generally given to drivers going straight, indicated by answer C. This rule helps prevent accidents and ensures a safer traffic flow. Traffic signals additionally contribute to regulating speed and improving intersection safety.
Step-by-step explanation:
The law regarding right of way at intersections is designed to provide clarity and safety to all road users. The correct answer to the question of who has the right of way at intersections is C. Drivers going straight. This is because drivers turning left or right are typically required to yield to drivers going straight, to prevent potential conflicts and collisions. For example, if two cars arrive at an intersection at the same time, the driver going straight has the right of way over the driver who wants to turn. Traffic signals also play a significant role in controlling traffic flow and ensuring safety. They force vehicles to slow down and adhere to the posted speed limit, reducing the likelihood of speeding through an intersection.
