When merging onto a highway, what is the best practice?

When merging onto a highway, accelerating to match the speed of traffic is the best practice because it helps to ensure a smooth and safe merging process. Highway traffic typically moves at higher speeds, and achieving a similar speed allows drivers to enter safely and reduces the likelihood of collisions.

When you approach the merge point, it's crucial to gauge the speed of vehicles already on the highway and adjust your speed appropriately. This means accelerating in the merging lane so that when you reach the point of merging, you can join the flow of traffic seamlessly.

This practice enhances safety for all drivers on the road, minimizing the chances of sudden stops or abrupt lane changes. In contrast, slowing down to match traffic or changing lanes sharply can create hazards for both the merging vehicle and those driving on the highway. Additionally, only looking to the left might limit awareness of vehicles that could be approaching from the right side, further increasing the risk of an accident.
