When a police officer is trying to decide if a driver is speeding, what is his point of reference? a. the ground b. his car c. the speed limit d. all of the above

C. The speed limit.

Explanation:

If the car was the point of reference then he would be looking at his car not the speed the car is going. If the ground was the reference then he would be looking at the ground and not how fast the car is going. So that means that the officer is determining how fast the car is going compared to the speed limit.
