Which driving condition primarily necessitates the use of turn signals?

The need for turn signals is crucial when changing lanes. This driving action directly involves moving your vehicle into a different lane, which can impact other road users. Using turn signals communicates your intentions to other drivers, reducing the likelihood of accidents by allowing them to anticipate your movements. It is a fundamental part of safe driving practices, as it ensures that everyone on the road is aware of your decisions, promoting a coordinated driving environment.

In other driving conditions, such as rainy weather or heavy traffic, while signaling is still important, the specific action of changing lanes is where the use of turn signals becomes especially vital for maintaining safety and awareness among all drivers. Night driving also requires turn signals, but visibility issues may place a different emphasis on caution rather than the act of signaling itself.
