This lesson focuses on teaching students about the technical navigation parameters necessary for planning safe travel for heavy vehicles. By the end of the lesson, students will be able to define key parameters such as bridge clearance, restricted routes, and multi-modal transit requirements. Through activities, students engage in analyzing routes for a hypothetical driver named Casey, who operates a heavy-duty freight truck. They learn to identify crucial signage, understand the importance of vehicle dimensions, and apply knowledge to real-world navigation challenges. The lesson emphasizes the need for professional flexibility and the risks associated with relying solely on standard GPS systems, encouraging students to use additional navigation resources for safe travel planning.
