How can a vehicle become unpredictable in traffic?

A vehicle can become unpredictable in traffic when the driver fails to communicate their intentions effectively. When a driver does not signal or provide any indication of their next move, other drivers on the road are left guessing about the vehicle's actions. This lack of communication can lead to confusion and increase the risk of accidents, as other motorists may not be able to anticipate lane changes, turns, or stops.

In contrast, maintaining a consistent speed, using turn signals properly, and obeying speed limits contribute to predictable driving behavior. These practices allow other drivers to anticipate what a vehicle will do next, significantly improving safety on the road. When drivers follow these rules, they promote a more organized traffic flow and reduce uncertainty for everyone sharing the roadway.
