Final answer:
The Speed Limit sign is often disobeyed, with individuals frequently exceeding posted limits despite potential safety concerns and legal consequences.
Step-by-step explanation:
A sign that people often disobey is b) Speed Limit. There is a common observation that many vehicles speed through intersections without regard to the posted speed limit. Despite the clear signage indicating the maximum allowed speed, drivers frequently choose to drive faster, leading to potential safety risks. Instituting a traffic signal could force vehicles to slow down and adhere to the speed regulations, preventing them from speeding through without caution.
In the broader context of social norms and symbols, signs like 'No Smoking', 'No Entry', and 'No Parking' are also commonly disregarded. These signs serve as cultural indicators of acceptable behavior, and when individuals choose to ignore them, they are reflecting a level of dissent from societal norms. For example, when someone parks in a 'No Parking' zone, they are making a decision that can lead to cultural sanctions or legal repercussions, such as fines or towing.
