Terms in this Study Set(13)
What is stopping distance?
The distance a vehicle travels from the moment a driver sees a hazard to when it stops.
Components of stopping distance?
1. Perception time 2. Reaction time 3. Brake distance
True or false: Speed affects stopping distance.
True, because higher speeds increase the distance needed to stop.
How does road condition affect stopping distance?
Wet, icy, or uneven roads can significantly increase stopping distance due to reduced traction.
Fill in the blank: Reaction time typically averages _____ seconds.
1.5 seconds
Difference between total stopping distance and braking distance?
Total stopping distance includes perception and reaction distances, while braking distance is just the distance traveled while braking.
Question: What increases stopping distances in adverse weather?
Reduced traction and increased stopping distances due to factors like rain and snow.
What is the formula for stopping distance?
Stopping Distance = Perception Distance + Reaction Distance + Braking Distance
How does speed of 60 mph affect stopping distance?
At 60 mph, the stopping distance can be around 240 feet under ideal conditions.
True or false: A heavier vehicle requires a longer stopping distance.
True, because it has more momentum and needs more distance to stop.
What is perception distance at 30 mph?
At 30 mph, perception distance is approximately 44 feet.
Fill in the blank: A driver’s reaction time is typically _____ seconds.
1.5 seconds
Question: What can reduce stopping distance?
Proper vehicle maintenance, good tires, and dry road conditions can reduce stopping distance.
