What are two main things drivers should look for ahead?

Focusing on vehicles coming onto the highway and brake lights from slowing vehicles is essential for safe driving because it helps drivers anticipate potential changes in traffic conditions. Being aware of vehicles merging onto the highway allows for proper adjustments in speed and lane positioning, preventing collisions. Additionally, noticing brake lights from drivers ahead signifies that traffic is slowing down, prompting the driver to prepare for a potential stop or reduced speed.

This understanding is crucial for maintaining a safe following distance and enabling proactive responses rather than reactive ones, which enhances overall roadway safety. Looking ahead at these factors equips drivers to make informed decisions, ensuring both their safety and the safety of others on the road.
