What is the correct procedure for merging onto a freeway?

The correct procedure for merging onto a freeway involves accelerating to match the speed of traffic and merging safely. This approach is essential for ensuring a smooth transition onto the freeway, which typically has higher speed limits and faster-moving vehicles. By accelerating to the flow of traffic, a driver reduces the risk of causing accidents due to sudden slowdowns or disruptions, which can occur if a vehicle tries to merge without matching speed.

When merging, it is also important to signal and check mirrors and blind spots to ensure that the merge can be performed safely without interfering with other vehicles. The emphasis on coordinating speed with that of the freeway traffic helps maintain the overall traffic flow and enhances safety for everyone on the road.

The other options present actions that would compromise safety: stopping in the merge lane can create hazards; failing to check blind spots can lead to collisions; and using the emergency lane is inappropriate during regular merging, as it is intended for emergencies only.
