Georgia DDA 6-Hour Defensive Driver & Driver Improvement Practice Exam

The best strategy when merging onto a controlled access highway is to accelerate relative to the traffic flow. This approach ensures that you match the speed of the vehicles already on the highway, allowing for a smoother and safer merge. When you accelerate to align your speed with the existing traffic, you reduce the likelihood of causing disruptions or accidents, as your entry into the flow is more seamless. The ability to merge effectively relies heavily on maintaining an appropriate speed, which not only helps you fit into the available gaps but also gives other drivers the opportunity to adjust their speed if needed, thereby enhancing overall road safety. In contrast, moving slower than the traffic flow can create hazardous conditions, as it may require other drivers to brake or maneuver unexpectedly. Relying on others to motion for you to merge could lead to delays and potentially dangerous situations, as it places an undue expectation on other drivers to facilitate your entry. Simply turning your head to look behind you, while necessary for checking your blind spot, does not address the critical aspect of speed adjustment necessary for a safe merge.
