12. Force of impact is determined by all of the following factors, except: A. Impact distance B. Driving experience C. Vehicle weight D. Speed of vehicle

To answer this question, let's analyze each option regarding the factors that determine the force of impact:

1. Impact Distance: This refers to how far a vehicle travels during the impact. While it can influence the severity of the consequences of an accident, it does not directly affect the force of the impact itself.

2. Driving Experience: This pertains to the skill and judgment of the driver. Although experienced drivers may handle vehicles better and reduce the risk of accidents, it does not directly determine the force of impact.

3. Vehicle Weight: The weight of a vehicle is a crucial factor in the force of impact. Heavier vehicles tend to exert more force upon impact due to their mass.

4. Speed of Vehicle: Speed is a critical factor as the force of impact is proportional to the velocity of the vehicle; higher speeds result in greater impact force.

Final Answer

The factor that does not determine the force of impact is B. Driving experience.
