Waiting restrictions indicated by signs generally mean that vehicles are not allowed to wait (stop and stay) in certain areas during specified times or at any time, depending on the sign and road markings. Waiting restrictions often apply to the entire highway including verges and footways but typically allow stopping briefly to pick up or set down passengers, and sometimes to load or unload if not otherwise prohibited. Common indicators of waiting restrictions include:

• Yellow lines along the edge of the carriageway. A single yellow line usually indicates that waiting is restricted during certain times, which are shown on an adjacent small yellow plate or nearby sign.
• Double yellow lines indicate no waiting at any time.
• Signs accompanying these road markings clarify the times when restrictions apply.
• In some controlled zones, signs indicate entry with restriction times, without separate yellow lines.
• Temporary waiting restrictions can also be indicated by portable signs.

Waiting restrictions do not normally prohibit loading or unloading unless specifically stated, and disabled badge holders may have some exemptions in certain areas. In summary, waiting restrictions mean you cannot park or wait at the roadside during times specified by the signs or road markings, but short stops to pick up or drop off passengers are usually allowed.
