Final answer:
Reflectors should be placed at the front, rear, and sides of a vehicle when stopped on a state highway to increase visibility.
Step-by-step explanation:
When stopped on a state highway, reflectors should be placed in the following locations:
- Place one reflector at the front of the vehicle, facing forward.
- Place one reflector at the rear of the vehicle, facing backward.
- Place one reflector on each side of the vehicle, facing sideways.
These reflectors help to increase visibility and indicate to other drivers that your vehicle is stationary.
