Final answer:
The correct way to enter a freeway is at or near the speed of freeway traffic, which helps maintain traffic flow and ensures safe merging.
Step-by-step explanation:
The correct answer is option d. To enter a freeway, you should enter the freeway at or near the speed of freeway traffic. This helps maintain the flow of traffic and allows for safer merging into the through lanes. On-ramps are designed to give vehicles enough distance to accelerate to a speed that matches that of the freeway. For instance, in a problem where a car accelerates from rest at a rate of 2.40 m/s² for 12.0 seconds, the objective is to reach a speed that allows for a smooth integration with the traffic already on the freeway. Stopping on the ramp is dangerous and can cause accidents, whereas entering the freeway too slowly can also be hazardous as it may cause other vehicles to brake suddenly or swerve to avoid a collision.
When entering a freeway, it is important to match the speed of the vehicles already on the freeway. This allows for a smooth merge and reduces the risk of causing a collision or disrupting the flow of traffic. If you enter the freeway at a significantly lower speed, it can put both you and other drivers at risk.
For example, if the speed limit on the freeway is 65 mph and the vehicles are traveling at that speed, you should aim to accelerate and merge at a similar speed. This ensures a safe and efficient entry onto the freeway
