Why do some states require specific hazmat routing plans, distinct from a driver's usual preferred route, for certain shipments?

Pick an answer

1. Routing plans are required purely to track fuel tax across state lines
2. To minimize risk by directing hazardous shipments away from densely populated or sensitive areas when a reasonable alternative exists
3. These plans exist only for cosmetic regulatory purposes with no practical safety benefit to anyone involved at all, a mistake that overlooks the real risk involved in that situation
4. Hazmat routing plans apply equally to every type of cargo, not just hazardous materials
