📏 Safety Distance - The Three Second Rule

Keeping the right distance to the vehicle ahead can save lives. It gives you time to react.
Three second rule: The simplest method for maintaining safe distance:
- Choose a fixed point (sign, pole, marking)
- When car ahead passes the point, start counting
- "One thousand one, one thousand two, one thousand three"
- You should reach the point AFTER saying "one thousand three"
Why three seconds?
- 1 second = reaction time (brain perceives danger)
- 2 seconds = braking time begins
- 3 seconds = safety margin
Increase distance when:
- Rain, snow or slippery (at least 6 seconds)
- Poor visibility (fog, darkness)
- High speed
- Heavy load
- Driving behind motorcycle/bicycle
- If you're tired
Distance in meters:
- 50 km/h → about 30 meters (3 car lengths)
- 70 km/h → about 40 meters
- 90 km/h → about 50 meters
- 110 km/h → about 60 meters
When someone drives too close behind you:
- Don't get irritated
- Increase your distance ahead (extra safety margin)
- Brake earlier and softer
- Let them pass if possible
Common mistakes:
- Reducing distance in queues = dangerous!
- Staring at car ahead instead of traffic
- Forgetting to adjust in bad weather
Remember: Distance costs nothing but can save your life. You'll arrive just as fast anyway.
