Final answer:
Weaving in and out of traffic on the highway causes more congestion and is unsafe. This behavior disrupts traffic flow and can lead to a chain reaction of slowdowns. Congested roadways result in higher pollutants and fuel consumption, demonstrating the importance of smooth traffic flow for safety and efficiency.
Step-by-step explanation:
The correct statement about weaving in and out of heavy traffic on the highway is that it causes more congestion, and therefore, it is not advisable to do it. Weaving through traffic is not only unsafe but also disrupts the flow of vehicles leading to even greater traffic congestion. This type of driving behavior can cause abrupt lane changes and sudden braking, which forces other drivers to react and can lead to a chain reaction of slowing down, thus adding to congestion.
Furthermore, the principle that shipping finished goods over congested street networks and jammed freeways increases costs and reduces profits supports the argument that congested roads are not ideal for transit. Studies have also demonstrated that slow speeds and idling of vehicles in heavy congestion lead to significantly higher levels of pollutants and fuel consumption.
Understanding traffic flow and its impact is therefore crucial for safety and efficiency on the road. This includes recognizing that practices that may seem time-saving, like weaving in traffic, can ultimately be counterproductive and dangerous.
