Facility signs give motorists information about facilities and directions. The current Traffic Police Basic Theory handbook describes them as black lettering on a white background with black borders. It describes tourist-place direction signs as white multilingual text, arrows and pictures on a brown background with white borders (SPF, Basic Theory of Driving, Part B, paras. 47–48).

The handbook says vehicles carrying dangerous goods must display hazard-information signs and gives “DANGER — HIGHLY FLAMMABLE” as an example (SPF, Basic Theory of Driving, Part B, para. 49).

That handbook example is not the full specification. For a licensee transporting petroleum or flammable materials, the Fire Safety (Petroleum and Flammable Materials) Regulations require the appropriate emergency information panel or warning labels under Singapore Standard SS 586, and any additional labels directed by the Commissioner. The panels or labels must be weather- and corrosion-resistant, indelibly marked, rigid or fixed to be rigid, attached in a substantially vertical plane, and kept clean and unobstructed. For multi-load tankers, the appropriate panel or label must appear on each tank or compartment containing the material. They must be displayed while the material is being transported and removed when the vehicle is no longer used for that transport; the display duty also covers an empty tank that an approved inspector has not certified as clean (Singapore Statutes Online, Fire Safety (Petroleum and Flammable Materials) Regulations, r. 46).

For licensed transport of petroleum or flammable materials in packages, rule 31 requires the label specified by the applicable Singapore Standard to be displayed conspicuously at the front, sides and rear, and the Regulations’ Third Schedule warning sign conspicuously at the rear. SCDF’s current vehicle inspection checklists distinguish placard locations by vehicle type: the goods-vehicle checklist says front, both sides and rear, while the road-tanker checklist says rear and both sides. These checklists also specify a rear “Danger, Highly Flammable” warning sign (Singapore Statutes Online, Fire Safety (Petroleum and Flammable Materials) Regulations, r. 31; SCDF, Vehicle Inspection Checklist).

The handbook describes long vehicles as goods vehicles longer than 10 metres, trailers longer than 5 metres, and mobile cranes longer than 10 metres. It says these vehicles must display at least 3 yellow reflective markings on each side and at least 1 red reflective marking at the rear; mobile cranes require rear markings only (SPF, Basic Theory of Driving).

SCDF’s current dangerous-goods transport circular directs other hazardous substances it lists, including corrosives, toxics and explosives and their precursors, to NEA or SPF requirements; these P&FM provisions therefore do not establish one universal placard rule for every dangerous-goods regime (SCDF, Transport Circular: Requirements on Road Transportation of Dangerous Goods, 1 October 2025).

The handbook describes long vehicles as goods vehicles longer than 10 m, trailers longer than 5 m, or mobile cranes longer than 10 m. It says long vehicles must display at least 3 yellow reflective markings on each side and at least 1 red reflective marking at the rear; mobile cranes require rear markings only. The handbook says these markings make long vehicles more conspicuous, especially at night (SPF, Basic Theory of Driving, Part B, para. 50).

The current Road Traffic (Motor Vehicles, Rear and Side Markings) Rules give more detail. Rules 3 and 4 cover rear markings for specified goods vehicles and trailers, including goods vehicles over 10 m, trailers over 5 m, trailers in a vehicle combination over 10 m overall, and mobile cranes over 10 m under the applicable registration provisions. Rule 4A requires applicable long goods vehicles and trailers to have at least 3 pairs of yellow retro-reflective side markings, with prescribed positions, dimensions, height, approval marking and maintenance requirements. If a projecting load makes a required rear marking on the vehicle not clearly visible, rule 5 allows that marking to be fitted to the load instead (Singapore Statutes Online, Road Traffic (Motor Vehicles, Rear and Side Markings) Rules, rules 3–5).

The handbook says buses, goods vehicles and trailers must display a marking stating the maximum speed in km/h at which the vehicle may be driven or drawn. It illustrates the marking with 70 km/h and 50 km/h examples; these illustrations do not set one speed for every vehicle in those classes (SPF, Basic Theory of Driving, Part B, para. 51). Rule 45B of the Road Traffic (Motor Vehicles, Registration and Licensing) Rules requires the owner of a public service vehicle other than a taxi, a goods vehicle, or a trailer to mark the maximum speed in km/h at which the vehicle may be driven or drawn. The marking must be in a conspicuous place determined by the Registrar. Drivers must obey both the vehicle’s marked maximum and the posted road limit, applying whichever is lower; rule 45B does not state a single speed for every vehicle in those classes (Singapore Statutes Online, Road Traffic (Motor Vehicles, Registration and Licensing) Rules, r. 45B).

  • This summary covers the cited petroleum and flammable-material transport requirements. It does not reproduce SS 586’s full class-specific panel layouts, label designs or dimensions, and does not consolidate separate NEA/SPF rules for every other regulated hazardous substance. Consult the current SS 586 and the responsible agency’s requirements for a particular load.
  • The handbook gives representative facility signs and the statutory marking schedule contains diagrams and minimum dimensions not reproduced here. The rules also require each new rear and side marking to carry a material approval mark and manufacturer trade name or mark (Singapore Statutes Online, Rear and Side Markings Rules, rules 4(4) and 4A(3)).
