Question

which of the following contributes to improved traffic flow? lowering the speed limit on major freeways not slowing down to look at an accident scene using your car instead of public transportation raising the speed limit on major freeways

Explanation:

• Lowering the speed limit on major freeways can cause traffic to slow down and potentially create bottlenecks, which is not good for traffic flow.
• Not slowing down to look at an accident scene helps maintain a consistent speed and reduces the likelihood of creating a secondary traffic jam caused by rubbernecking.
• Using your car instead of public transportation increases the number of vehicles on the road, which can lead to more congestion.
• Raising the speed limit on major freeways, if done without proper infrastructure or driver training, can lead to unsafe driving and potential accidents, which would disrupt traffic flow.

Answer:

Not slowing down to look at an accident scene.
