Before proceeding at a stop sign or traffic light, a driver should do what?

Before proceeding at a stop sign or traffic light, the appropriate action for a driver is to look for vehicles, pedestrians, and bicyclists. This action is essential because it ensures the safety of all road users. Drivers must be vigilant about their surroundings and assess the traffic conditions before making any moves. By checking for other vehicles, pedestrians waiting to cross, and bicyclists in the vicinity, a driver can prevent accidents and contribute to a safer driving environment.

Prioritizing this awareness over other options reflects responsible driving behavior. While checking a phone or adjusting a rearview mirror may seem quick and harmless, these tasks can distract from the critical need to observe traffic. Similarly, turning on hazard lights is typically reserved for emergencies and would not apply in this context where the driver must focus on traffic around them. Thus, the correct choice highlights the importance of situational awareness and precaution before continuing through an intersection.
