Road Signs, Signals and Road Markings
This domain tests whether you can read Grenada's UK-derived signing system at a glance: what a sign's shape and colour require, how the traffic-light sequence works, and what the painted markings on the carriageway mean. Questions usually show a sign or describe a road scene and ask for the correct action, not just the sign's name.
Sign families
- Red circles prohibit or restrict: no entry, a speed limit, no overtaking, no parking.
- Blue circles give a positive instruction: turn left, keep left, mini-roundabout.
- Red-bordered triangles warn: bend, junction, pedestrian crossing, slippery road, school.
- Rectangles give information or direction. The octagon is reserved for STOP; the inverted triangle means GIVE WAY.
Traffic lights
- Red: stop behind the stop line.
- Red and amber together: prepare to go, but do not move off.
- Green: proceed only if the way ahead is clear.
- Amber: stop, unless you are so close that stopping would be unsafe.
- At a pedestrian crossing with a flashing amber light, give way to anyone on the crossing.
Road markings
- A broken white centre line may be crossed to overtake when it is safe.
- Double solid white lines must not be crossed.
- A solid white line at a STOP sign means stop at the line, not before it or on it.
- A broken line across your lane at a junction means give way.
- Double yellow lines at the kerb mean no waiting or parking at any time; single yellow lines carry posted restrictions.
- Zebra stripes are a pedestrian crossing: give way to people on it.
Worked example
You approach a junction and see an octagonal sign with a thick solid white line across your lane. The cross-road traffic is moving. What must you do? The octagon is the only sign that imposes a full stop. You stop at the line, check both directions, and move off only when there is a safe gap. Slowing to a crawl and rolling forward because the road looks clear is a common error; the stop is compulsory even when nothing is coming.
Traps that cost marks
- Treating a warning triangle as a legal order.
- Reading a blue circle as a warning.
- Accelerating on amber instead of stopping when safe.
- Stopping on top of a zebra crossing or a stop line.
- Confusing no entry (red circle with a white bar) with no vehicles.
