A 3-minute lesson from the Indiana course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Warning signs prepare you for road conditions and hazards ahead. Most are yellow diamonds. Work zone warnings are orange, and school signs may be fluorescent yellow-green.
Orange construction signs warn you to be careful approaching construction zones. Some give guidance (Detour) or regulations (Worksite Added Penalties).
Yellow or fluorescent yellow-green school zone signs (School Crossing, School Crossing Ahead, School Bus Stop Ahead) mean you're entering an area near a school where children may be crossing.
You pass an orange Worksite Added Penalties sign, then a Worksite Speed Limit 45 sign. Slow to 45 and stay alert for workers. You must obey the posted speed limit in a work site.
