Final answer:
You must wait for the approaching vehicle going straight ahead before you turn left because they have the right of way. A traffic signal can improve intersection safety by regulating vehicle speeds and pedestrian crossings.
Step-by-step explanation:
When you want to turn left at an intersection and there is a vehicle approaching from the opposite direction going straight, you must wait for the approaching traffic to go through before you turn. This is because the vehicle going straight has the right of way, and turning vehicles must yield.
When you want to turn left at an intersection, you must wait for approaching traffic to pass before you turn because the approaching vehicle has the right of way. The rules of the road prioritize vehicles going straight ahead over those making left turns. By waiting for the approaching vehicle to go through the intersection, you are ensuring that you are not interfering with their right of way.
This rule helps to prevent collisions and ensure that traffic flows smoothly and safely at intersections. Furthermore, the presence of a traffic signal at such intersections can enhance safety by controlling the speed of vehicles and providing orderly movement of both vehicular and pedestrian traffic.
