It is illegal to park your vehicle:
- In an unmarked crosswalk. ✓
- Within three feet of a private driveway.
- In a bicycle lane.
Answer: A. In an unmarked crosswalk.
It is illegal to park on a marked or unmarked crosswalk, so parking in an unmarked crosswalk is against the law.
Why this is the answer
The handbook's list of places where you may never park or leave your vehicle includes a marked or unmarked crosswalk. An unmarked crosswalk is still a crosswalk, so it falls under the same rule as a painted one. That space belongs to pedestrians crossing the road, and the handbook treats it as off limits for parking rather than as a spot you can use when nothing is painted on the pavement.
Why the other answers are wrong
- B. Within three feet of a private driveway. — The three-foot distance in the handbook applies to a sidewalk ramp for disabled persons, not to a private driveway; driveways are covered by the rule against blocking one.
- C. In a bicycle lane. — The passage about bike lanes deals with driving in one briefly before a right turn, and the never-park list quoted here does not name bicycle lanes, so this choice is not what the handbook supports.
Remember it
If it is painted for people on foot, or flat enough that people cross there, keep your car off it.
