Trinidad & Tobago Mandatory Signs
Indicate actions that must be taken
5 signs in this category
Mandatory signs tell you what you must do on Trinidad & Tobago roads — the direction you must travel, a minimum speed, or a lane you must use. Ignoring them is a traffic offence.
Study tip: Mandatory signs are typically circular with a blue background and a white symbol. Remember: a blue circle means you must; a red circle means you must not.
