Delaware Driver Education State Practice Test

What does a speed limit sign regulate?

1. The maximum speed allowed on a stretch of highway

2. The minimum speed allowed in construction zones

3. The speed at which emergency vehicles can pass

4. The suggested speed for heavy vehicles

The correct answer is: The maximum speed allowed on a stretch of highway

A speed limit sign is a critical element of traffic regulation that informs drivers of the maximum speed permitted on a particular stretch of roadway. This regulation is established to ensure the safety of all road users, promoting orderly traffic flow and reducing the likelihood of accidents. The numerical value displayed on the speed limit sign indicates the fastest legal speed under ideal driving conditions, which drivers are expected to adhere to. While there are other regulations concerning minimum speeds, specific considerations for emergency vehicles, and suggestions for heavy vehicles, these do not fall under the authority of a standard speed limit sign. Instead, they pertain to different traffic management strategies or signage designed to address those unique circumstances. Therefore, the essence of a speed limit sign is to set clear maximum speed thresholds for vehicular movement.
