what are the 3 principles a driver should follow (in french)
VOIR
PENSER
AGIR
agir= changing speed (vitesse) or idstance of security, communicating with others, etc.
what is important to avoid risks
not thinking this wont happen- rather constantly be vigiltant & take steps
what should you NOT do to avoid risks
don’t underestimate
if you’re not sure wait & see
don’t overcross roads if you don’thave good visibllity
what is the average amount of time to switch from brake to accelerator, and how much distance is travelled in this time?
1 second; During this second the vehicle travels 13.89m at 50km/h without any action by the driver on the brake pedal.
what do you need to know to anticipate the ‘temps d’arreter’
importance of reaction time (temps du reaction) and understand the influence of speed on the braking distance (vitesse & distance du freinage).
what is the ‘distance d’arret’
the distance traveled during reaction time
+
distance traveled during braking distance.
how long does the distance d’arret last
Stopping distance begins when you notice the hazard and ends when the vehicle comes to a complete stop.
what is a good tip when a pedestrian might pass while you’re driving?
put leg on brake and start slowing down already to lower distance d’arret
what is the order of events while deciding whether to stop
Percieve Identify Analyze Decide Act (agir)
what does the ‘reaction’ time depend on
degree of vigilance of driver and speed
what does the braking distance depend on
vehicle performance, pavement state (l’etat de la chaussee), speed
what is the reaciton time
time between reacting and acting (1 second= 25 meteres at 90 km/hr)
how does weather affect distance of stopping?
increases the distance of braking by x2
how does speed influence distance d’arrret (examples at 130 vs 50 m)
at 130 km/h:
- reaction time distance= 36 m travelled
- braking distance= 82 m travelled
= total 118 m travelled
at 50 km/h:
reaction time= 14 m travelled
brakign distance= 12 m
= 26 m travelled
how do you choose the speed at which you travel?
usually there are authorized maximums (road signs/ conditions you’re in) but its best to travel lower than maximum allowed either way
but generally choose a speed where you can have a safe distance from the behaviour of other drivers
+ your distance d’arret does not cross over with a zone of uncertainity

why do you need to takae distance from others while driving
to have time to see, think and act safely and leave intrevals for the temps d’arret & temps du reaction
what interval of time should calculate to ensure a good distance from other drivers
2 seconds (in city/road/highway)
how do you calculate your ‘distance du securite’
Multiply the number of 10th (i.e. 50km/h=5) of speed by 3 and then multiply the result by 2 to gain the 2 second distance
i.e. 5 x 3= 15
hence distance should be:
15m x 2 seconds= 30 m distance
i.e. 110km h
11x3=33
33x2= 66 m distance
how should you keep distance on the highway
= look at the white lines on the road to know the distance needed to keep space safely. (length of 2 tracks= 2 seconds of security at 130 km/hr)
how should you keep distance in a tunnel
TUNNEL blue lights indicate distance of security (length of 2 blue lights= safe distance)
how can you commincate
its important; using ‘clignonants’ (lights) and audio-visual body language + horn (klaxon)
when can you use the klaxxon
in sitautions of IMMEDIATE danger
what should the last person in a traffic line do?
put on their distress lights (feux de distress)
