What is the appropriate way to merge onto a highway?

Answer: B — Speed up to match the traffic flow before merging

The appropriate way to merge onto a highway is to speed up to match the traffic flow before merging. This is crucial as it allows for a smoother integration into the existing traffic, minimizing the risk of accidents. When you accelerate to the speed of the vehicles already on the highway, you reduce the likelihood of disrupting the flow of traffic and creating a hazardous situation for yourself or other drivers. Merging at a speed that is close to that of highway traffic ensures that you can find a suitable gap to enter safely without forcing other drivers to change their speed or position unexpectedly. Proper merging techniques promote safety and efficiency on the road, which is essential in high-speed environments like highways.
