Sample question from test 5
signs
At a stop sign with a marked stop line, where should the vehicle stop?
- At or beyond the crosswalk so the driver can see cross traffic
- At the stop line, before the vehicle reaches it
- Beside the sign, even if that is inside the intersection
- Only after another vehicle has stopped first
Answer: At the stop line, before the vehicle reaches it. The stop line establishes the first stopping point, so the vehicle should halt before reaching it. If a crosswalk is present, it also must remain clear, and the driver may pull forward later only when necessary to see and only after yielding as required. Stopping beside the sign can place the vehicle in the intersection, while waiting for another vehicle misunderstands the independent duty to stop. Approach early enough to brake smoothly, keep the crosswalk open, and look for crossing traffic before moving forward.
