What constitutes an offense in relation to obeying warning signs and barricades?

Disobeying instructions from signages constitutes an offense because it directly relates to the law's intention to ensure the safety of drivers, pedestrians, and road workers. Warning signs and barricades are established to inform individuals of potential hazards, changes in road conditions, or other important instructions that must be followed for public safety. When someone fails to adhere to these indications, it poses a significant risk not only to themselves but also to others on the road.

In this context, ignoring road markings may be related but does not necessarily represent the broader scope of offenses against explicitly stated instructions. Driving under the speed limit is generally considered safe and compliant with traffic regulations, hence it does not qualify as an offense. Therefore, the focus on disobeying signage is crucial in understanding traffic laws and the emphasis on public safety measures.
