How do you properly merge onto a highway?

Merging onto a highway requires understanding how to seamlessly integrate into the flow of traffic while maintaining safety for everyone on the road. The correct answer emphasizes the importance of using the acceleration lane to match the speed of traffic. This approach allows a driver to gradually increase their speed to align with that of vehicles already traveling on the highway.

Using the acceleration lane provides the necessary distance to adjust your speed and safely merge without causing disruption to the ongoing traffic. It creates a smooth transition from the entrance ramp onto the main roadway, which is essential for avoiding collisions and ensuring the safety of all road users.

While the other options may seem relevant, they do not address the practicality of merging as effectively. For instance, stopping before merging disrupts the flow of traffic and creates hazards. Relying solely on speed limit signs without considering the current speed of traffic could lead to unsafe merging scenarios. Waiting for a gap is necessary, but failing to accelerate adequately might cause delays or force other drivers to make sudden adjustments, negating the safety of the merge. Therefore, utilizing the acceleration lane to match the speed of existing traffic is the most effective and safest method for merging onto a highway.
