Road signs in Mauritius are standardised traffic signs used in Mauritius according to the Traffic Signs Regulations 1990 (French: Règlement sur la Signalisation Routière 1990). They are heavily modelled on road signs in the United Kingdom, since Mauritius is a former British colony. Mauritius drives on the left.

The traffic sign are divided into three classes; circles gives orders, triangles warns of possible dangers and rectangles gives information. Different colours are use within these shapes; blue circles are mandatory signs, it gives positive instructions, while red circles are prohibitory signs, it give negative instructions. Blue rectangles give general information while green rectangles are use for direction sign on main roads. However, there are three exception for these shapes and colour rules; that is the octagonal Stop sign, the diamond priority road sign and the inverted red triangle Give way sign.^[1]
