Highway SafetyMV Act 2019, Section 122 – unsafe following distance fine ₹500; NHAI 2-second rule advisory
Tailgating on the Highway
Rule: Maintain 2-second following distance at 80 km/h; increase to 4 seconds in rain or fog
1
Mumbai-Pune Expressway, monsoon, 80 km/h
Sharma follows the car ahead at 8-metre distance — 'Highway mein lane kya chhodoon, sab koi hataata hai.'
→ Car ahead brakes hard for a pothole. Sharma takes 30m to stop on wet road. Rear-ends the car at 20 km/h — airbags deploy, ₹40,000 bumper damage.
✓ Lesson: On wet roads, braking distance triples — the 2-second rule becomes a 4-second minimum.
2
Same highway, dry weather
Sharma picks a fixed marker (milestone) — when car ahead passes it, he counts 'one and two' before reaching it.
→ He naturally maintains 40+ metres of buffer. Three emergency stops — zero contact.
✓ Lesson: The 2-second count is a skill, not a feeling — feelings lie; the timer doesn't.
3
Highway rest stop, father-son conversation
Sharma teaches his son the milestone-count method while they're stationary.
→ Son practices it on the rest of the journey. 'Papa it works — you can actually see more road ahead too.'
✓ Lesson: A comfortable following distance also reduces driver stress and improves decision time.
