New Hampshire Drivers Practice Test

Merging onto an expressway requires you to adjust your speed to match the flow of traffic. Increasing your speed is critical because expressways are designed for vehicles to travel at faster speeds, typically ranging from 55 to 70 mph, depending on the area. When you accelerate to meet or closely match the speed of existing traffic, you help ensure a smooth transition into your lane and reduce the risk of collisions. This is essential not only for your safety but also for the safety of other drivers, as a significant speed difference can lead to dangerous situations. For instance, coming to a complete stop disrupts the flow of traffic and increases the likelihood of being rear-ended. Similarly, reducing your speed or hesitating to merge could create gaps in traffic that other drivers might find difficult to navigate safely. Therefore, increasing your speed allows for a safer and more effective merging process.
