Which of the following describes improper lane changes?

Improper lane changes can often be attributed to a lack of vigilance, which includes the failure to properly observe traffic conditions, blind spots, and the behavior of other drivers. When a driver is not paying adequate attention to their surroundings, they may make abrupt or unsafe lane changes that can lead to dangerous situations, such as collisions.

Vigilance involves being aware of and responsive to one’s driving environment, which is crucial for making safe lane transitions. A vigilant driver would observe when it’s safe to change lanes, ensure that there are no vehicles in their blind spots, and signal their intentions clearly to other road users. In contrast, issues such as judgment problems may relate more to decision-making rather than observational skills, and road safety compliance refers to adhering to laws and regulations which, while related, doesn’t specifically address the attentiveness required for lane changes.
