Matching the speed of the traffic and yielding as necessary is considered a safe action when merging onto a highway because it enables a smooth integration into the flow of traffic. Highways are designed for higher speeds, and approaching at a similar speed helps maintain the momentum and safety of both the merging vehicle and the vehicles already on the highway. Yielding where necessary ensures that you give way to vehicles that have the right of way, which reduces the risk of collisions and maintains traffic flow.

Opting to speed up and force your way in can create a dangerous situation, as it may lead to aggressive driving and possible accidents. Slowly approaching without checking traffic can result in a failure to gauge the speed and distance of oncoming vehicles, increasing the likelihood of an unsafe merge. Waiting until the highway is clear is impractical in most scenarios, as highways are usually busy, and doing so can create confusion and disrupt the flow of traffic if everyone attempted to wait for a clear path. Thus, the proper merging strategy helps ensure safety for all road users.
