When are hand signals or lamps required for vehicles?

Hand signals or lamps are required when turning or stopping to ensure that drivers communicate their intentions clearly to other road users. This is particularly important as it enhances safety on the roads by making the actions of the vehicle predictable to others, such as cyclists, pedestrians, and other drivers.

Using hand signals or lamps during turns or stops allows for better coordination and can prevent accidents by alerting others of your immediate plans. For instance, when planning to turn left or right, raising an arm can indicate the direction, while the use of lamps serves a similar purpose both in daylight and nighttime conditions.

While it is true that visibility plays a role in safe driving and that drivers need to be aware of their surroundings at all times, hand signals and lamps do not need to be used continuously or under every circumstance, making them specifically necessary during the critical moments of turning or stopping.
