Road Signs, Signals and Road Markings
Antigua & Barbuda follows the international sign families you see across the Caribbean: regulatory signs (usually circular, red border or blue circle) tell you what you must or must not do; warning signs (triangular with a red border) alert you to a hazard ahead such as a bend, junction or pedestrian crossing; information signs (rectangular, often blue or green) guide you to places and services. Learn the shape and colour logic rather than memorising individual pictures, because questions often describe a sign in words.
Signals matter as much as signs. A steady red means stop and remain stopped; a flashing amber at a pedestrian crossing means give way to anyone on the crossing; a green arrow only permits movement in the arrow's direction. Police or authorised officer signals override all lights and markings - a common trap. Road markings carry legal force: a solid centre line means do not cross, a broken line may be crossed when safe, and double lines reinforce the no-overtaking rule. Stop lines, give-way lines (broken) and box junctions must be read correctly.
Traps: questions swap 'must' for 'should', or show a warning triangle where the answer expects a regulatory meaning. Another trap is confusing a give way instruction with a stop - a stop line always requires a complete stop even if the road looks clear.
Rule of thumb: red = prohibition or danger, blue = mandatory or information, triangle = warning, circle = command. If a sign's shape is red-bordered and triangular, ask 'what hazard am I being warned about?' before choosing an answer.
