Final answer:
When a divided highway ends, drivers should prepare to merge safely by checking traffic, adjusting speed, and changing lanes if necessary. The safety of a rabbit crossing a highway is unpredictable and depends on traffic conditions.
Step-by-step explanation:
When you see a sign indicating that a divided highway ends, and you should prepare to change lanes or shift lane position, it implies that the separate roadways for opposing traffic are about to merge or intersect. This typically means that the physical barrier or median that separates the highway directions is coming to an end.
As a driver, it's important to assess the traffic around you, check your mirrors, and safely merge into the correct lane as the roadway configuration changes. This may also involve reducing your speed and increasing your awareness of the vehicles around you, as lanes might merge or intersections may appear.
If a car is traveling in the lane furthest from a crossing animal, such as a rabbit, this does not guarantee the safety of the animal crossing all lanes. High-speed vehicles can pose significant danger, and the rabbit's crossing may still be risky.
