What is the correct procedure for merging into traffic on a highway?

Matching the speed of traffic before merging is a crucial step in ensuring a safe and successful merge onto a highway. When you approach the merging point, it is essential to accelerate to a speed that is close to the vehicles already traveling in the lane you intend to enter. This reduces the likelihood of causing a sudden stop or creating a dangerous situation for both yourself and other drivers.

By matching the speed of traffic, you create a smoother transition and allow for better predictability in movement, as other drivers can anticipate your actions more easily. This also minimizes the risk of collisions that can occur if vehicles are traveling at significantly different speeds when merging.

Merging directly into a lane without proper speed can lead to abrupt maneuvers that may surprise other drivers, increasing the potential for accidents. Therefore, being aware of the traffic flow and adjusting your speed accordingly is essential for safe merging practices.
