A vehicle approaching an intersection should give priority to which vehicle?

The correct answer emphasizes the rule of priority at intersections, which is typically based on the type of road from which vehicles are approaching. A vehicle coming from a wider road generally has the right of way because wider roads are usually designed to accommodate higher volumes of traffic and are often viewed as having a priority over those coming from narrower or less significant roads. This prioritization helps prevent accidents and ensures a smoother flow of traffic at intersections.

This understanding is grounded in traffic management principles where vehicles on more significant highways or roads are expected to continue their path without interruption, signaling to drivers on smaller or secondary roads the need to yield. Thus, when a vehicle is approaching an intersection, prioritizing those from wider roads aligns with safe driving practices and adherence to traffic laws.

The other options reflect scenarios that may not align with standard prioritization rules. For instance, vehicles from normal roads may not have the same level of priority as those on wider roads, and immediately signaling hazard lights does not inherently determine right of way at intersections. Lastly, giving priority to vehicles from left side roads is contrary to general traffic laws which dictate that priority is given to vehicles on larger roads.
