What is the consequence of not using signals when changing lanes?

When a driver changes lanes without using signals, it creates confusion for other road users. Signals are a crucial part of communicating intentions on the road; they inform other drivers and pedestrians of what a motorist plans to do next. Failing to signal can lead to misunderstandings, as nearby drivers might not expect a lane change, increasing the likelihood of collisions. The potential for an accident arises because other drivers may not have adequate time to react to an unexpected movement, which could result in dangerous situations.

While there may be other implications such as warnings from law enforcement or points on a driving record, the immediate and most significant consequence of not signaling is the heightened risk of an accident, making it critical for drivers to always use proper signaling when changing lanes.
