If a driver is unsure about a speed limit, what should they do?

When a driver is unsure about a speed limit, the best course of action is to look for posted limits or signs. This approach ensures that the driver adheres to the correct speed limit that is legally established for that particular road or area. Speed limits are put in place for safety and can vary based on factors such as road type, local regulations, and specific conditions. By checking for signs, the driver can obtain the most accurate and relevant information regarding the speed they should maintain, promoting safety and compliance with traffic laws.

Other strategies, such as following the flow of traffic, might not always be safe or legal, as the flow could exceed the actual speed limit. Assuming a general speed limit without verification can lead to unintended violations, while driving as slowly as possible can create danger and frustration for other road users. Thus, verifying the posted limits is the most responsible and effective action.
