Step-by-step explanation:
When driving, it is important to scan the entire driving scene ahead to anticipate any potential hazards or obstacles. The recommended amount of time to scan ahead is about 12-15 seconds. This allows you to have enough time to react to any changes in traffic, road conditions, or potential dangers.
For example, if you are driving at a speed of 60 mph, scanning ahead for 12-15 seconds would mean looking at least half a mile or more down the road. This gives you a better understanding of what is happening ahead and helps you make better decisions while driving.
By scanning the entire driving scene ahead, you can identify any upcoming intersections, changes in traffic patterns, or potential hazards that may require you to slow down, change lanes, or take any other necessary actions to ensure your safety.
