What additional information must be included in a route plan beyond the origin and destination points?

Including all planned stops in a route plan is crucial when transporting hazardous materials. This information helps ensure compliance with safety regulations and allows for proper management during the transportation of hazardous materials. Planned stops may include refueling locations, rest breaks, or places to transfer cargo. Knowing where these stops will occur enables the driver and the transportation company to assess risks associated with each location and prepare adequately. Safety precautions can be implemented to mitigate potential hazards, and emergency plans can be developed for each stop if needed.

While estimated travel time, weather conditions, and the driver's contact information are certainly valuable, they do not directly address the complexities and safety considerations involved in transporting hazardous materials the way that a thorough understanding of planned stops does. The focus on stops emphasizes the need for thorough planning to maintain safety throughout the transportation process.
