Comprehension Survey CommentsComprehension Survey Comments
“I think any sign with a picture is more attention catching and memorable…”
“Having an image helps understand the signage…”
“I think a visual is helpful and it's important to say where to move the vehicle – to the shoulder.”
“Figure 3 [the IMTF sign] can be easily understood because of the picture and the verbage is concise…”
“I prefer Figure 3 [the IMTF sign] because the graphic is more eye-catching and more understandable for limited-English speakers than "fender bender," and because it is tied for the shortest at six words.”
“I think the sign should have a picture as well as stress the ‘no injury’ part.”
“I'm not sure that a typical motorist understands "Fender Bender"; signage should probably not rely on this term.”
“The sign should include: ‘It’s the Law’.”
