Final Answer:
The recommended time/distance that you should NOT be looking ahead for driving safety is 100 feet. Option 4 is correct.
Step-by-step explanation:
Looking ahead in driving is crucial for safety. While 2 to 3 seconds, 1 to 2 blocks, and half a mile are all recommended times/distances for maintaining awareness, looking just 100 feet ahead limits reaction time significantly. For optimal safety, drivers are advised to scan about 12-15 seconds ahead, equal to roughly one city block or a quarter-mile on highways, ensuring ample time for reaction in case of sudden changes.
Five car lengths, approximately 70 feet, falls short in providing the necessary reaction time, emphasizing the significance of a broader field of vision. The 100-feet mark restricts the ability to anticipate hazards and adapt to changing road conditions promptly, underscoring the importance of looking farther ahead for proactive and safer driving practices.
Correct answer: 4) 100 feet
