Road signs in Singapore closely follow those laid down in the traffic sign regulations used in the United Kingdom, although a number of changes over the years have introduced some slight deviations that suit local road conditions (such as fonts). Road signs in Singapore conform to the local Highway Code under authority of the Singapore Traffic Police.
The Highway Code of Singapore Traffic Police is tested during the Basic Theory Test and Final Theory Test at either Ubi, Bukit Batok or Woodlands driving schools. The students are then to find either a school or private driving instructor to learn driving itself. Singaporean road signs depict people with realistic (as opposed to stylised) silhouettes.
No official name is given to the typeface used on all official signs, which resembles closely to Enamela Condensed Medium.
Warning signages warn of possible dangers or unusual conditions ahead and alert motorists on the hazards to expect. They are usually shaped as triangles with a red border, mounted on a borderless white backing board.
General warning sign (old type)
Other dangers; plate beneath will state nature of danger
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 provides interdependent exceptions to the rule, or indicates additional instruction or information to facilitate understanding of the rule implemented.
Mandatory signs are generally circular with a white border and symbol on a blue background. They usually indicate something all drivers must do (e.g. keep left) or a facility available to certain classes of traffic (e.g. pedal cycles only).
Ahead only (Turning left and right is prohibited)
Turn left ahead (right if symbol is reversed)
Turn left (right if symbol is reversed)
Keep left (Right if symbol is reversed)
Split-way, i.e. motorists can pass to either side, but either side might not reach the same destination
Route to be used by pedal cycles only
Route to be used by pedestrians only
Route to be shared by cycles and pedestrians
Segregated route for pedal cycles and pedestrians (Cycles on left; pedestrians on right). Symbol may be reversed.
The exceptions are the octagonal red STOP sign, the triangular GIVE WAY sign and the various mandatory STOP signs that are circular and have a red border.
Stop and give way
Give way to traffic on a major road
School crossing patrol (sign held by school wardens)
Mandatory stop for police checks
Mandatory stop for Customs at checkpoint
Mandatory stop for private property security checks
Prohibitory signs, which generally tell drivers what they must not do, are mostly circular and have a red border. The red ring indicates the prohibition; diagonal bars are used only on signs which prohibit a specific manoeuvre, i.e. banned left or right turns and U-turns, or a certain class of vehicle, i.e. lorries.
No entry for vehicles in both directions, including pedal cycles
No entry for all vehicular traffic
No pedal cycles
No vehicles carrying explosives
No vehicles with 3 axles or more
No sounding of vehicle horn
No waiting on side of road where sign is displayed
No stopping on side of road where sign is displayed
National speed limit applies
No jaywalking in the bus park
No left turn
No right turn
Diagonal bars are excluded when restrictions are quantitative in nature, i.e. limits in speed, weight, axle, height and width.
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.
Indication of a U-turn lane, on the lane closest to the road divider or carriageway
One way traffic ahead (Turning left and right is permitted)
Temporary work-zone signs are mounted to ensure roads keep a free flow of traffic despite being affected by road works in the vicinity. They are depicted as orange diamond, orange rectangular or yellow rectangular shaped signs.
Advance sign of road works ahead
Indication of road stretch affected by road works
Entry to works area
Heavy vehicles turning ahead
Heavy vehicles turning ahead
Layout of lanes ahead
Layout of lanes ahead
Road narrows on right ahead
Temporary mandatory speed limit (40km/h)
Traffic lights in use ahead
Bend to right (Left if symbol is reversed)
Supplementary plate to specify direction indicated for temporary road rule
Single lane traffic
Curve Alignment Marker (Bend to direction indicated)
Detour for pedestrians in direction indicated (Right)
Two flashing amber beacons 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.
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.
