What indicates a vehicle may not be familiar to the driver?

A driver who is operating a vehicle recklessly might suggest a lack of familiarity with the vehicle. Reckless driving behaviors can include erratic lane changes, sudden acceleration or braking, and an inability to navigate turns smoothly. These actions may indicate that the driver is struggling to control the vehicle or is unaware of its handling characteristics, which are often better understood by someone who is more experienced with that particular car.

In contrast, playing loud music or having passengers present does not necessarily imply any level of familiarity with the vehicle; these behaviors could occur regardless of the driver's experience. Moreover, consistently using turn signals is typically a sign of a responsible driver who is aware of the rules of the road and is likely familiar with their vehicle, as it suggests they are taking care to communicate their intentions to other road users. Thus, these alternative options do not convey the same implications about the driver's experience with the vehicle.
