English: Specific Weight Limit sign R12-I100a from the Illinois supplement to the Manual on Uniform Traffic Control Devices, with text converted to paths for display. The specific numbers come from [1] since the standard specifies the same number for each weight limit, which is not ideal for illustrating this kind of sign.
Any traffic control device design or application provision contained in this Manual shall be considered to be in the public domain. Traffic control devices contained in this Manual shall not be protected by a patent, trademark, or copyright, except for the Interstate Shield and any other items owned by FHWA.
