Emergencies & HazardsPregunta 83 de 120
A car pulls out directly in front of you and there is not enough distance to stop. What is generally the best response?
a.Brake as hard as possible and hold the pedal down
b.Sound the horn and maintain speed
c.Downshift and hope the gap clears
d.Steer around the hazard if there is an escape path, because a vehicle can change direction faster than it can stop
Explicación
Stopping distance grows with the square of speed, but the time needed to steer around an obstacle changes very little, so an evasive steer is often the only option that works. Locking the brakes destroys steering control, the horn does not shorten the closing distance, and downshifting is far too slow to help.
