Which action is NOT recommended when preparing to pull out from the curb?

Pulling back into the street without looking is not recommended because it poses a significant safety risk. When you prepare to pull out from the curb, it's crucial to be aware of your surroundings to ensure that you do not collide with pedestrians, cyclists, or other vehicles. By checking all mirrors, using turn signals, and looking over your shoulder, you create better visibility and awareness of the traffic conditions. Each of these actions is essential for safe driving, as they help you to confirm that the lane is clear before merging back into traffic. Therefore, neglecting to look can lead to dangerous situations, making it a critical point to understand in driving safety.
