Final answer:
When merging onto the freeway, the goal is to match your speed to the flow of traffic, taking care to remain within legal speed limits and drive safely according to the traffic conditions.
Step-by-step explanation:
When merging onto the freeway, you should be driving at a speed that matches the flow of traffic, as long as it is safe and legal. While the speed limit is the legal maximum, actual driving speed will vary based on traffic conditions. If traffic is moving slower due to congestion, you should merge at a speed that is safe and allows for smooth integration into traffic. Conversely, if traffic is moving at the legal limit and it is safe to do so, you should aim to match this speed to avoid causing disruptions. Always be aware that exceeding the speed limit can result in a traffic citation, and driving significantly slower than the traffic flow can create hazards. Therefore, the best practice when merging onto a freeway is to adjust your speed according to existing traffic conditions, within the bounds of traffic laws.
