Sample question from test 4
signs
What must a driver do at a Colorado STOP sign?
- Come to a complete stop
- Continue if no vehicle is visible
- Stop only if a train is approaching
- Slow down without stopping
Answer: Come to a complete stop. A Colorado STOP sign requires a complete stop. The driver must stop at the marked stop line, or, if no line exists, before entering the near-side crosswalk. If neither is present, stop at the point nearest the intersecting roadway where approaching traffic can be seen. Merely slowing down is not enough, even when the intersection looks empty. The train-only choice confuses railroad controls with an ordinary stop requirement. After stopping, check for pedestrians and other traffic before proceeding. The advance warning image does not itself replace the actual stop control.
