Warning, Construction & Information SignsStandalone practice
Before you can read the symbol on this sign, its shape and color already tell you what kind of message it gives. What should you get ready for?
Correct answer: A possible hazard or change in the road ahead that can make you slow down
Why
Shape and color tell you the kind of message from far away, before you can read the words or the symbol. Common warning signs show a curve, a lane that ends, a signal ahead or a slippery road. Some warning signs, such as those for school zones and pedestrian crossings, are a bright fluorescent yellow.
