Road signs in Singapore

Warning signs indicate possible dangers or unusual conditions ahead and alert motorists, so they may anticipate the appropriate actions to take. They are usually shaped as triangles with a red border, and mounted on a borderless white backing board, which is similar to the United Kingdom traffic sign.

Regulatory signs either give positive instructions, i.e. Mandatory signs, or indicate a prohibition, i.e. Prohibitionary signs. Many regulatory signs are accompanied by supplementary plates that provide interdependent exceptions to the rule, or indicates additional instruction or information to facilitate understanding of the rule implemented.

Information signs are signs that may be mounted to indicate a certain condition or nature of the road ahead that motorists need to take note. They are independent of existing mandatory and prohibitive signs. Such signs are usually white or blue and rectangular in shape.

A zebra crossing in Singapore

Two flashing Belisha Beacon are positioned, one on each side of the road, at a zebra crossing, which flashes from 7 pm to 7 am daily, indicating to an approaching motorist of a zebra crossing. Older crossings display the blue square zebra crossing signs on both sides (see above), which are synonymous to the flashing amber beacons, and are valid yet uncommon on the roads. The road markings and road dividers are white zig-zag lines that indicate a zebra crossing in the vicinity, similar to the United Kingdom and Republic of Ireland Zebra crossing rules.

On approach, regardless of the absence of any pedestrians, all motorists are required to keep left of the divider, prepare to stop and stay in their respective lanes, i.e. no overtaking is permitted.

When pedestrians are present at the side of a zebra crossing, all motorists are obligated to give priority to pedestrians crossing the zebra crossing bars, by stopping before the white line across the lane. No waiting is permitted within the vicinity of the zebra crossing.

A sign indicating a pedestrian crossing or a 'SLOW' painted on the road may be present as well.
