Special **vehicles** must drive **on the right** on roads within built-up areas. This is because, like other vehicles, they must follow the general traffic rules that indicate driving on the right. Additionally, these vehicles do not have special priority to pass or overtake, which reinforces the need to follow standard traffic rules.

It is important to remember that, although special vehicles may have certain unique features, such as yellow lights to indicate their presence, they must respect the same basic traffic rules as other vehicles, including driving on the right.
