Drivers entering an intersection to turn left:
Answers
Can wait in the intersection until they can turn left.
Can wait in the intersection until the light turns yellow before turning left.
Must wait for the green arrow before turning left.
Must not enter an intersection unless they can get through it without having to stop.
The correct answer and explanation is:
The correct answer is: “Must not enter an intersection unless they can get through it without having to stop.”
Explanation:
When drivers approach an intersection with the intention of turning left, they must be aware of traffic laws and guidelines designed to ensure the safety and efficiency of traffic flow. The key principle here is that drivers should not enter an intersection unless they can clear it entirely without needing to stop, especially if the signal is about to change or traffic conditions suggest it could create congestion.
Why drivers should not enter an intersection if they can’t clear it:
- Gridlock Prevention: One of the main reasons for this rule is to prevent gridlock, which occurs when vehicles block the intersection, preventing cross-traffic from moving freely. If a driver enters an intersection and cannot complete their turn due to oncoming traffic or other obstacles, they create a blockage that can affect all vehicles in the intersection. This disrupts the flow of traffic and causes delays.
- Safety Concerns: When drivers stop in the intersection while waiting for a chance to turn left, they may be in a hazardous position. They are exposed to potential collisions from vehicles approaching from behind or from oncoming traffic if they are waiting in a way that interferes with the movement of other cars.
- Compliance with Traffic Signals: Traffic signals are designed to control the flow of traffic safely. In many cases, a left-turn signal will have specific rules, such as requiring a green arrow to turn left. Entering an intersection when not able to complete the turn might cause confusion, especially for drivers who are following the green signal and expecting the intersection to be clear.
Conclusion:
Therefore, the best practice for drivers approaching an intersection to turn left is to ensure they can complete their turn without stopping in the middle of the intersection. If they cannot do so, they should wait until the intersection is clear and they are able to complete their turn safely. This principle helps maintain the flow of traffic and prevents unnecessary risks.
