Final answer:
When entering an expressway, you must check traffic flow, signal and adjust your speed to create space, and then accelerate smoothly and merge.
Step-by-step explanation:
When entering an expressway, you must:
- Check traffic flow from entrance ramp: Before merging onto the expressway, it's important to look for any oncoming vehicles and assess the traffic flow.
- Signal and adjust speed to create space: Signaling your intention to merge and adjusting your speed appropriately helps create a safe gap for you to enter the expressway.
- Accelerate smoothly and merge: Once you have found a suitable gap in traffic, accelerate smoothly to match the speed of the expressway and merge into the traffic flow.
