Final answer:
When reaching the end of an on-ramp while getting onto an expressway, it is important to be traveling as close as possible to the speed of traffic. This ensures a smooth and safe merge onto the expressway, as matching the speed of traffic allows for efficient merging without causing disruptions or accidents.
Step-by-step explanation:
When reaching the end of an on-ramp while getting onto an expressway, it is important to be traveling as close as possible to the speed of traffic. This ensures a smooth and safe merge onto the expressway, as matching the speed of traffic allows for efficient merging without causing disruptions or accidents.
For example, if the speed of traffic is around 60 miles per hour, it would be ideal to match that speed when entering the expressway. This helps to maintain a consistent flow of traffic and minimizes the risk of collisions.
By traveling at a speed less than the speed of traffic, it can create dangerous situations, such as drivers behind having to abruptly slow down or change lanes to avoid collisions. Therefore, option (A) - traveling as close as possible to the speed of traffic - is the correct choice.
