What is the best way to inform other drivers of a maneuver you are about to make on the highway?

Using your signals is the most effective way to inform other drivers of a maneuver you are about to make on the highway. Turn signals are specifically designed to communicate your intentions clearly and unambiguously. When you use your signals, you indicate whether you plan to turn, change lanes, or merge, allowing other drivers to anticipate your actions and adjust accordingly. This practice significantly contributes to overall road safety by reducing the potential for confusion among drivers.

While other methods like using your horn, making eye contact, or waving your hand can help in certain situations, they can be less reliable or misinterpreted. Horns are typically used to alert others to immediate dangers rather than to signal a planned maneuver. Eye contact may not always be possible or may not guarantee understanding, and hand gestures can also be easily misunderstood. Therefore, utilizing turn signals remains the standard and most effective means of communication on the road.
