Compliance overview
Scope and applicability
This standard specifies the classification, color, shape, character, size, graphics, setting, use, maintenance, and manufacturing requirements for road traffic signs. It applies to highways, urban roads, and public areas including squares and parking lots. It is mandatory for all road traffic sign manufacturers and road management authorities in China. It does not apply to traffic markings, which are covered in GB 5768.3.
Technical requirements
The standard defines the general requirements for traffic signs, emphasizing that they must meet road user needs, attract attention, and convey clear meanings without causing information overload. It classifies signs into main signs (prohibitory, indicative, warning, guide, tourist, and notice) and auxiliary signs. A significant update in this version is the introduction of fluorescent fire red as the background color for traffic accident management warning signs, replacing the previous fluorescent pink. The standard also specifies detailed requirements for sign colors, shapes, and characters, including the use of specific fonts (Type A, B, and C) for different applications. For sign dimensions, the standard provides tables correlating sign size with design speed. Manufacturers must strictly adhere to these dimensional requirements to ensure visibility and compliance. It also includes new provisions for variable message signs (VMS), specifying their display content, color usage, and installation conditions to avoid interfering with traffic signals.
Testing methods
The standard does not specify laboratory testing methods but outlines visual and structural inspection criteria. This includes verifying the correct color, shape, and size of signs according to the design speed. It also details the installation requirements, such as the angle of the sign face, height from the road surface, and clearance from the roadway. For variable message signs, the standard requires checking brightness levels to avoid glare and ensuring synchronization of flashing elements.
FAQs
What is the main difference between GB 5768.2-2022 and the previous 2009 version?
The 2022 version introduces several updates, including the addition of fluorescent fire red for accident management signs, new sign types like electric bicycle signs, and revised requirements for sign fonts and dimensions.

Does GB 5768.2-2022 apply to variable message signs (VMS)?
Yes, the standard includes a dedicated section for variable message signs. It specifies that VMS should not display non-traffic-related information, must use specific colors for different message types, and should reduce brightness in low-light conditions to prevent glare.
Are there specific font requirements for the text on traffic signs?
Yes, the standard mandates the use of specific traffic sign fonts categorized as Type A, B, and C. Type A is for general text, Type B is for road numbering and exit numbers, and Type C is for road numbers on guide sign arrows. Using the correct font is essential for legibility and compliance.
