Distance and location
A good distance and correct position in the field are the basis for safe driving. Here are the rules.
Distance and location are all about giving yourself enough time to react and enough room to maneuver. Correct field position makes you visible and predictable to others.
Distance forward
Use the three-second rule as a starting point:
| Ratio | Recommended distance |
|---|---|
| Dry road, good visibility | 3 seconds |
| Wet driving | 4 seconds |
| Smooth winter driving | 5–6 seconds |
| Fog or very poor visibility | Increase further, reduce speed |
The distance in meters increases with speed. At 80 km/h three seconds corresponds to approx. 67 m, which gives you margin to stop within the stopping distance .
Distance to page
- Cyclists and pedestrians: Keep at least 1.5 m distance when passing
- Oncoming traffic: Reduce your speed if the road is narrow and it is difficult to keep your distance
- Parked cars: Keep at least a door-width distance in case someone opens the door
Location in the lane
- Drive in the middle of the field as standard
- Lay down to the right before turning right at intersection
- Lay down close to the center line before the left turn
- Avoid being close to the center line on narrow roads with oncoming traffic
Backward distance
You cannot control the car behind you directly, but you can:
- Keep a steady speed so that the car behind can predict your movements
- Increase the distance forward if someone is too close behind you, so that you can brake more softly
- Avoid sudden braking that could lead to a collision from behind
Special situations
- Tunnels: Keep extra distance because stopping distance in tunnel is critical
- Motorway: High speed requires a longer distance
- Queue: Even at low speed you need distance to avoid emergency brake
- Turn: Reduce speed and keep a good distance through curves
