Why should you avoid making sudden lane changes?

Answer: A — It can surprise other drivers and increase the risk of collisions.

Making sudden lane changes can surprise other drivers, which significantly increases the risk of collisions. Sudden movements can catch following vehicles off guard, leaving them little time to react or adjust their speed. This unpredictability adds a layer of danger to the driving environment, as rear-end or side-impact collisions are more likely to occur. Additionally, other drivers may not anticipate your move if they are not given adequate signals or space to adjust. Therefore, making lane changes gradually and with clear communication through indicators helps ensure that all road users can respond safely and appropriately. While it might be tempting to think that using turn signals or driving faster is sufficient justification for sudden lane changes, these actions do not mitigate the overall risk involved. Consistent and predictable driving patterns contribute to safer roadways for everyone.
