What is especially important when choosing the speed for driving along tree-lined avenues with narrow roadways?

When driving on narrow roads lined with trees, it is important to correctly estimate the lateral distance to both the trees and oncoming traffic, because there is little room for error. If a wide vehicle approaches from the opposite direction, you may not have enough space to pass safely at normal speed. In such cases, you must be able to stop within half the visible distance, as the road ahead could be blocked. Estimating these distances and adjusting your speed is essential to avoid accidents or collisions. Rapidly changing light conditions do not make distance estimation easier and are not a reason to increase speed. For similar questions, always focus on safety margins and the need to adapt speed for narrow or potentially obstructed roads.
