Sample question from test 7
signs
What do red roadway signs indicate?
- Regulatory instructions that must be obeyed
- Optional directions to recreation areas
- Warnings about construction equipment only
- Services such as fuel or food
Answer: Regulatory instructions that must be obeyed. Red signs are regulatory signs and must be obeyed. Illinois examples include STOP, YIELD, DO NOT ENTER, and WRONG WAY. They are not optional recreation guides, construction-only warnings, or service markers. When red appears on one of these signs, treat the instruction as a traffic control command and follow the required action before continuing. The color signals that the instruction is mandatory.
