When merging onto a highway, what is a recommended action?

When merging onto a highway, turning off your signal is generally not recommended. Instead, the most appropriate action is to use your signal to indicate your intention to merge. Proper signaling communicates your plans to other drivers, helping to ensure safety and smooth traffic flow. While it’s crucial to signal, it's important to also match your speed to that of the traffic on the highway to make the merge more seamless.

Using your horn to alert others can create confusion and is often unnecessary if you are signaling appropriately. Speeding up excessively can lead to dangerous situations if other vehicles are not aware of your presence. Similarly, braking suddenly can cause issues for both you and drivers behind you, as it may lead to collisions. Thus, the focus should always be on clear communication, safe merging techniques, and adjusting your speed appropriately.
