Minnesota Permit Practice Test

The correct answer is that a driver should obey a sign immediately upon seeing it. Following a posted sign is essential as it conveys important information regarding rules and regulations that are crucial for safe driving and road navigation. For instance, a speed limit sign indicates the maximum legal speed on that stretch of the road; ignoring it could result in dangerous situations or traffic violations.

While it may seem reasonable to contemplate obeying a sign only after passing it or at a complete stop, this approach can lead to unsafe behaviors on the road, such as abrupt braking or not responding to critical warnings like stop signs or yield signs in due time. Being attentive to signs the moment they are visible allows drivers to make necessary adjustments before reaching the sign's location, enhancing overall traffic safety and compliance with road laws.
