When we put our entire driver handbook online, I made it a priority to turn a lot of our key instructional graphics into animated video format. Today the SGI public website has more than 60 animated videos explaining proper driving techniques and providing examples of how fault is determined. Monthly analytics place these videos among the most visited pages on the corporate website.
The traffic circle (or roundabout) is a perfect example where a video can explain so much more than a static image could.
