When merging onto a highway, what should you do first?

  1. Maintain speed and merge when there is a gap in traffic

  2. Increase speed to match the flow of traffic

  3. Turn on your signal light

  4. Check for other vehicles and adjust speed

The correct answer is: Check for other vehicles and adjust speed

When merging onto a highway, your first priority should be to check for other vehicles and adjust your speed accordingly. While maintaining speed and merging when there is a gap in traffic may also be necessary, it is important to first ensure that merging can be done safely without causing any collisions. Increasing speed to match the flow of traffic may also be necessary, but only after checking for other vehicles and ensuring a safe merge. Turning on your signal light is important, but it should not be the first action taken when merging onto a highway.
