Explanation:

🆕 New Concept Discovered: Three-Second Rule
Safe following distance in normal driving conditions

Step 1: Identify the standard safety rule for following distance

Under ideal driving conditions, traffic safety administrations (such as the Illinois DMV/Secretary of State) recommend maintaining a minimum following distance of at least 3 to 4 seconds behind the vehicle directly in front of you. This is often referred to as the "three-second rule."

Step 2: Compare with the given options

• A: 1 second behind the vehicle ahead — Too short; does not allow enough reaction time.
• B: 2 seconds behind the vehicle ahead — Formerly a common standard, but modern safety guidelines recommend more time to ensure a safe stopping margin.
• C: 3-4 seconds behind the vehicle ahead — Matches the recommended safety standard for ideal conditions.
• D: As close as possible to the bumper — Extremely dangerous (tailgating).

Answer:

C: 3-4 seconds behind the vehicle ahead
