Final answer:
Changing lanes should be done gradually and carefully, ensuring no car is in your blind spot, and is a key part of being a cautious and attentive driver.
Step-by-step explanation:
Changing from one lane to another is best done gradually and carefully. It is important to avoid quick and frequent lane changes, which can be hazardous and create unnecessary risk. Also, it is crucial to ensure that no car is in your blind spot before changing lanes. When driving, being observant and making decisions based on road conditions and the behavior of other drivers is essential. For example, one must gauge the speed and distance of other vehicles, such as the scenario where you must estimate if it is safe to cross the road with an oncoming car that is 28 meters away. In the end, the goal is to maintain safety for yourself and others by being a cautious and attentive driver.
