Should frequent lane changes be avoided on the expressway?

Frequent lane changes on the expressway should indeed be avoided because they can create unsafe conditions for both the driver making the changes and other vehicles on the road. Making frequent lane changes increases the likelihood of collisions, as it reduces the driver's ability to maintain awareness of their surroundings, including blind spots where other vehicles may be. Furthermore, changing lanes often can lead to sudden movements that might surprise other drivers and cause them to react unpredictably.

On expressways, where speeds are typically higher and traffic is more dynamic, maintaining a stable and predictable driving pattern is essential for safety. This allows all drivers to anticipate each other's actions and respond accordingly, thereby reducing the risk of accidents. Keeping lane changes to a minimum enables more efficient merging and helps in maintaining overall traffic flow.
