At 50km/h this corresponds to about 15m. For higher speeds up to about 100km/h outside built-up areas a similarly defined 2-second rule applies, which for 100km/h translates to about 50m. For speeds on the order of 100km/h there is also the more or less equivalent rule that the stopping distance be the speed divided by 2 k/h, referred to as halber tacho (half the speedometer) rule, e.g. Accid Anal Prev. ahead.

This content is provided by the NIH National Institute on Aging (NIA). The time between the onset of a stimulus and the start of an overt response.Reaction time, or RT, is a measurement of the speed of response. This means that a driver who is sleepy can take longer to see and recognize a hazard in the road, which impacts his or her overall reaction time and makes it more difficult for the driver to avoid a hazard. General fatigue can also affect perception while driving, as someone may become more likely to lose focus or stare at one point in the road and become less aware of hazards or other vehicles.
