Final answer:
If the entrance lane is too short to allow acceleration to highway speed, the correct option is C - merge into highway traffic as soon as possible.
Step-by-step explanation:
If the entrance lane is too short to allow acceleration to highway speed, the correct option is C, merge into highway traffic as soon as possible.
When the entrance lane is too short, it means there is not enough space to accelerate to match the speed of the highway traffic. In this situation, it is important to merge into the highway traffic as soon as possible to avoid disrupting traffic flow or potential accidents. By merging into the traffic, you can adjust your speed and find a safe gap to enter the highway without impeding the flow of other vehicles.
Merging into the traffic requires caution and attentiveness. You should use your turn signals to signal your intention, check your blind spots, and smoothly merge into a gap in the traffic. It is also important to adjust your speed to match the flow of the traffic on the highway.
