The image is a blue and white sign with the words "Why Speed Matters" written in bold letters at the top. Below the text, there are three illustrations that explain why speed matters. 

The first illustration on the top left shows a car driving on a road with a speed limit of 20 mph. The second illustration shows a person walking on a sidewalk with a car in the background. The third illustration shows the speed limit for a vehicle traveling at 30 mph.

At the bottom of the sign, there is a text that reads "Hit by a vehicle: 20 mph, 30 mph, 40 mph, and 40 mph." The text below the illustrations explains that speed limits are not acceptable for people who are not allowed to drive on the road. The sign is attached to a pole and is located on a street with cars and buildings in the distance.
