RULE OF THUMB 
 
 
The most important rule of thumb, which you need for the theoretical examination, summarized again for you.
 Reaktionsweg:
   Recognize - decide - react
We humans assume a reaction time of about one second
the reaction path in m 
 
 
Example:
speed: 80 km/h
reaction time 2 seconds
 
Bremsweg:
   From the start of braking to the standstill of the vehicle.
Braking distance in m
 
 
 
Example:
speed: 40 km/h
  
 speed: 40 km/h
Emergency braking:
Stopping distance:
  Detect the danger until the vehicle comes to a standstill
Stopping distance in m = reaction distance in m + braking distance in m
 
Stopping distance in m = reaction distance in m + braking distance in m
Example:
speed: 60 km/h
 
Stopping distance with emergency braking:
Example:
speed: 60 km/h
