Question

you can greatly ______ your risk of a collision by learning how to navigate the highway transportation system and by using safe skills. reduce increase develop balance

Explanation:

To solve this, we analyze the context: learning to navigate the highway system and using safe skills should logically lower the risk of a collision. "Reduce" means to make smaller or less, which fits. "Increase" would mean raising risk (opposite of what's intended). "Develop" is about creating or growing, not fitting for risk. "Balance" implies equalizing, not relevant here.

Answer:
