What should you do when merging onto a highway?

Merging onto a highway involves integrating your vehicle into fast-moving traffic, and therefore it is crucial to accelerate to the speed of traffic. This ensures that you can merge safely and smoothly without disrupting the flow of vehicles already present on the highway.

When accelerating to match the speed of traffic, you help maintain safety for yourself and other drivers by reducing the chances of collisions that occur when vehicles are traveling at significantly different speeds. It’s important to be aware of your surroundings and use your mirrors appropriately during this process to identify gaps where you can merge.

Other options do not align with safe merging practices. Slowing down and yielding to all vehicles could create dangerous situations, as it can cause confusion and impede the flow of traffic. Using your horn to alert other drivers is generally unnecessary and could be considered aggressive driving. Changing lanes without checking mirrors ignores critical safety protocols, as it increases the risk of accidents by not being aware of vehicles in adjacent lanes.
