What does the octagon shape tell a driver about a traffic sign?
- It identifies a no-passing zone
- It marks a railroad advance warning
- It is used exclusively for stop signs
- It marks a guide sign to a service
Answer: It is used exclusively for stop signs. The octagon is reserved for stop signs, making its shape useful before the lettering can be read. A railroad advance warning uses a round yellow sign or a white crossbuck, and the sideways triangle identifies a no-passing zone. Service information is commonly shown on blue square or rectangular signs. If an octagonal sign comes into view, begin slowing and prepare for a complete stop rather than treating it as a general warning.
