- A marking to emphasize and indicate sidewalks of different heights,
- Correct answer: Absolutely no stopping, except for the vehicle types that are permitted by the sign.
- Parking is permitted with parking tickets.
- Unrestricted parking for public vehicles is permitted.
Why this is the answer
The correct answer in the official bank: Absolutely no stopping, except for the vehicle types that are permitted by the sign.
A red-yellow marking on a curbstone means that all stopping is prohibited at that place, except for the type of vehicle that a nearby sign permits to stop. The marking is not meant to emphasize sidewalks of different heights, and it does not indicate parking with parking tickets or unrestricted parking for public vehicles.
