What defensive measure should be taken when approaching an intersection?

When approaching an intersection, it is crucial to look both ways before entering, regardless of signals. This defensive measure enhances safety by ensuring that the driver is aware of any potential hazards, such as vehicles running red lights or pedestrians crossing the road. Even when traffic signals indicate that it is safe to proceed, doing a visual check helps prevent accidents. Intersections are common locations for collisions, as they involve multiple lines of traffic that may not always adhere to the rules. By looking both ways, drivers can identify any surprises, react appropriately, and make safe decisions about proceeding through the intersection.

Other choices do not promote safety and can lead to dangerous situations. For instance, accelerating to beat a red light increases the risk of accidents. Ignoring pedestrians neglects the right of way that they are often afforded, while choosing to only follow traffic signals neglects the need for awareness of the actual traffic environment.
