MDOT - Transportation Standards and Special Details Pavement Markings Regulations / Standards On August 5, 2022, FHWA published a final rule in the federal register adding new provisions to the Manual on Uniform Traffic Control Devices (MUTCD) relating to maintaining minimum levels of pavement marking retroreflectivity.

Option: Lane line markings should also be used at congested locations where the roadway will accommodate more traffic lanes with lane line markings than without the markings. The following is a list of construction forms. 01 Speed reduction markings (see Figure 3B-28) are transverse markings that are placed on the roadway within a lane (along both edges of the lane) in a pattern of progressively reduced spacing to give drivers the impression that their speed is increasing. Contract Detail - Illinois Each updated codebook corresponds with a regularly scheduled IDOT Letting. 03 If used on the roadways of divided highways or one-way streets, or on any ramp in the direction of travel, left edge line pavement markings shall consist of a normal solid yellow line to delineate the left-hand edge of a roadway or to indicate driving or passing restrictions left of these markings. 08 Except for the two opposing arrows of a two-way left-turn lane marking (see Figure 3B-7), the longitudinal space between word or symbol message markings, including arrow markings, should be at least four times the height of the characters for low-speed roads, but not more than ten times the height of the characters under any conditions. 02 The spacing for such applications should be 2N, where N equals the length of one line segment plus one gap (see Section 3B.11).
