Which type of sign denotes a speed limit on a road?

Regulatory signs are crucial for maintaining order and safety on the roads, as they provide specific instructions that must be followed by all drivers. Speed limit signs fall under this category because they set a legal limit on how fast vehicles can travel on a particular stretch of road. This regulation is designed to protect all road users – including drivers, passengers, pedestrians, and cyclists – from the dangers associated with speeding.

On the other hand, informative signs aim to provide information, such as directions or locations, but do not impose rules that must be followed, which distinguishes them from regulatory signs. Warning signs alert drivers to potential hazards ahead, such as curves, slippery roads, or pedestrian crossings, but they do not set specific limits or regulations. Direction signs help navigate and guide drivers to their desired destinations, lacking any legal implications for drivers' behavior on the road. Thus, the correct identification of speed limit signs as regulatory signs emphasizes their importance in traffic management and safety.
