Observation, Speed & SpaceStandalone practice
Driver A travels at 30 mph. Driver B travels at 60 mph on the same dry road. Both see a hazard at the same moment and brake hard. What is true about the distance that each driver needs to stop?
Correct answer: Driver B needs more than twice the distance that Driver A needs
Why
The Washington guide warns that higher speeds make stopping distances longer and give you less time to react. A small increase in speed adds a large amount of braking distance. For this reason, speeding makes a crash more likely, and the higher force of impact makes injuries more severe.
