Question

which laws or rules prevent or reduce injury in the event of a crash?
a. signaling rules
b. speed limits
c. impaired - driving laws
d. passing rules

Explanation:

Speed limits reduce the kinetic energy of a vehicle in case of a crash, thus minimizing the impact force and potential injury. Signaling rules and passing rules mainly help in preventing crashes rather than reducing injury in a crash. Impaired - driving laws aim to prevent crashes by keeping intoxicated drivers off the road.

Answer:

B. Speed limits
