Precision work: The time trial
regularity rallies, also called time-speed-distance rallies (tSd), are a type of
time trial. they are indicated by a yellow road sign (tSd 1/100). at the signpost,
an official gives the drivers a hand signal telling them when to start. time is
recorded beginning after a few meters, coinciding with a red flag signal when
the vehicles pass a photoelectric sensor or pressure hose sensor. the co-driver
presses the stopwatch at this starting line and begins measuring the target time.
the team should continue driving once the tSd has been completed so as not
to hinder the vehicles behind it.
lichtschranke = Photoelectric sensor
Schlauch = Pressure hose sensor
