Minimum speed signs are designed to
A. Show current local road conditions.
B. Assure pedestrian safety.
C. Keep traffic flowing smoothly.
D. Test future traffic signal needs.
Answer: C. Keep traffic flowing smoothly.
Speed limit signals are designed for a reason – roadblocks to maintain the level of traffic flow between certain roads and motorways. This type of sign is normally installed in certain locations where slower vehicles would result in the hindrance of the general flow of the road traffic, such as freeways or expressways with higher speed limits. In ensuring a minimum speed limit the driver is greatly motivated to drive effectively and thus will always follow the pace of other vehicles which may not be too slow. This not only estimates time requirements but also hopefully eliminates any bottleneck; congestion, or potential accidents occurred due to the significant differences in speed between various vehicles on the road. Speed Minimum signs are more than just a figure of speed, they provide the possibility of a uniform and harmonious operation of a traffic stream, which has the ultimate goal of the security which is guaranteed by the appropriate and fast enough movement on the roads
