17 Calculation of the overtaking distance

The speed difference for overtaking should be at least 20 km/h. The viewable distance should be twice the overtaking distance.

Rule of thumb

Overtaking distance =	Higher speed x Higher speed
	Speed difference

Example: The overtaking vehicle travels at 80 km/h, the vehicle to be overtaken travels at 60 km/h.

Calculation: 80 km/h x 80 km/h : 20km/h = 320 m

Example 2: The overtaking vehicle travels at 60 km/h, the vehicle to be overtaken travels at 30 km/h.

Berechnung: 60 km/h x 60 km/h : 30km/h = 120 m

Note: The greater the speed difference during overtaking, the shorter the overtaking distance.
