Answer:
The correct answer is C. Higher fines.
Research has shown that higher fines for speeding can act as a deterrent and reduce speeding among teens. When teenagers face the prospect of steeper fines, they are more likely to follow speed limits and drive more responsibly. Other factors such as the behavior of other drivers, the use of seat belts, and better roadways can contribute to overall road safety, but specifically for reducing speeding in teens, higher fines have been proven to be effective.
