Is it advisable to use hand and arm signals in bright sunlight?

Using hand and arm signals while driving is indeed a wise practice, particularly in bright sunlight. These signals serve as an additional means of communication with other drivers, which can enhance safety on the road. When visibility is compromised due to bright lights or the sun's glare, hand and arm signals can still be seen clearly, especially when electronic turn signals may be less noticeable. This method allows drivers to convey their intentions – such as turning or stopping – effectively.

In situations where other vehicles or pedestrians may not see brake lights or turn indicators as clearly, hand signals provide a reliable alternative, reminding others on the road of your actions. This is particularly critical in environments where quick and clear communication can prevent accidents.

The idea of using hand signals only on highways or under certain conditions is less comprehensive, as clear communication is vital regardless of the driving environment. It's also important to note that relying solely on hand signals when signal lights are malfunctioning is not sufficient, as a combination of methods is always the safest approach to ensure that other road users are aware of your intentions.
