Which of the following is considered a reckless driving behavior?

Reckless driving is characterized by behavior that shows a willful disregard for the safety of others. Operating a vehicle erratically is a clear example of such behavior. This can include swerving, rapid acceleration and deceleration, sudden lane changes without signaling, and other actions that could endanger the driver, passengers, and other road users. Such driving not only increases the likelihood of accidents but also reflects a failure to adhere to the standard expectations for safe driving practices.

In contrast, driving under the speed limit, yielding right-of-way, and using indicators while turning are all behaviors that contribute to safe driving. These actions demonstrate a driver's commitment to following traffic laws and maintaining order on the road, thereby minimizing risks to themselves and others.
