Idaho Written Driver's License Practice Test 2025 – The All-in-One Guide to Exam Success

When merging onto a highway, it is essential for a driver to speed up to match the flow of traffic. This action is important because highways are designed for higher speed travel, and maintaining a similar speed to that of the vehicles already on the road ensures a smoother and safer transition into the traffic. By matching speeds, the driver minimizes the risk of collisions that could occur if they were to enter the highway at a significantly slower pace.

Driving at the appropriate speed encourages safe gaps in traffic to merge into, allowing for more predictable behavior from other drivers. It is also crucial for the driver to use their mirrors and check blind spots while accelerating to merge effectively. In contrast, options that suggest slowing down or stopping at the entrance ramp can lead to dangerous situations, such as causing bottlenecks or impeding the progress of vehicles already on the highway. Additionally, signaling only when other vehicles are present does not contribute to proactive communication; a driver should always signal their intent to merge, regardless of the presence of other vehicles. This practice ensures that all road users are aware of the driver's intentions, promoting safety for everyone on the road.
