Final answer:
When on a freeway entrance, it is important to stop moving and become stationary until it is safe to merge into traffic.
Step-by-step explanation:
When you are on a freeway entrance and have to wait for a gap in traffic before you can enter the roadway, the best course of action is to stop moving and become stationary until a safe opportunity to merge arises.
This allows you to assess the flow of traffic, observe the speed and behavior of other vehicles, and ensure that it is safe to merge without causing any disruption or danger to yourself or other drivers.
Once you have identified a suitable gap in traffic, you can then proceed to enter the roadway.
