A no-parking zone is defined as what?
Answer: A — A no-parking zone is areas where parking is prohibited; look for signs or curb color that indicate restrictions.
No-parking zones are areas where parking is prohibited at all times; the restriction is shown by signs or curb color that indicate no parking. This distinguishes it from areas with time-based restrictions (no parking during certain hours), loading zones (for loading/unloading only), or bus stops (where stopping for buses is required). The key idea is that a no-parking zone means you cannot park there, and the signs or curb markings communicate that permanent prohibition.
