Why is it important to look for brake lights from slowing vehicles?

Answer: B — To prepare for possible hazards

Looking for brake lights from slowing vehicles is crucial because it helps drivers prepare for possible hazards on the road. When you observe a vehicle's brake lights illuminate, it indicates that the driver is reducing speed, which could signal various scenarios such as an upcoming stop, an obstacle in the road, or traffic congestion. Being aware of these signals allows you to adjust your speed and position accordingly, ensuring you maintain a safe distance and can react appropriately to any sudden changes in traffic conditions. This proactive approach enhances overall safety for both the driver and other road users.
