Answer:
The correct answer would be option B. Garn exceeded the federal time limit
Explanation:
Most jurisdictions in the world regulate the number of hours a truck driver can drive without taking a rest. This is because driving for long hours, without rest of sleep can cause a driver to make wrong decisions and cause an accident.
In this case, the accident was directly caused by Gran because he was breaking the law and has exceeded limits. This lead to a local disaster which might be dangerous and will definitely cost a lot of money to clean up.
