Mandatory Signs: Practice Questions

Mandatory signs are blue circles with white symbols, and they tell you what you must do rather than what to avoid. The questions cover minimum speed signs such as 35 km/h and their end signs, ahead only, turn left or right only, keep left or right, pass on either side, combined directions and the roundabout sign. You also practise the difference between a blue order sign and a red-framed warning triangle that looks similar, and what you may or may not do when a sign allows only certain directions.
