In practice, this comes down to the following:

• Not having access to the same adjoining properties.
• Not to cross at ground level any other path, road, railway line or tramway, nor to be crossed at ground level by any path, communication route or right-of-way.
• Consist of different carriageways for each direction of traffic, separated from each other, except at specific points or temporarily, by a strip of land not intended for traffic or, in exceptional cases, by other means.

In short, the rule makes sure every road user knows what to expect in this situation.

The exam often asks where and to whom these rules apply; read the options carefully, as they frequently change a single word.
