What is the best way to communicate with other drivers while on the road?

Using turn signals and brake lights is the best way to communicate with other drivers while on the road because these signals are specifically designed for this purpose. Turn signals indicate your intention to change lanes or make a turn, which helps other drivers anticipate your movements and adjust accordingly to prevent accidents. Similarly, brake lights alert other drivers when you are slowing down or stopping, providing crucial information that can prevent rear-end collisions and enhance road safety.

Hand signals can be useful but are often not as visible or understood, particularly at night or in adverse weather conditions. Frequent lane changes can lead to confusion and create unsafe scenarios as it does not provide clear communication about your intentions. Honking your horn may signal urgency or alertness but can also be interpreted as aggressive or startle other drivers, which is not an effective form of communication compared to the clarity provided by turn signals and brake lights.
