The Manual on Uniform Traffic Control Devices for Streets and Highways (usually referred to as the Manual on Uniform Traffic Control Devices, abbreviated MUTCD) is a document issued by the Federal Highway Administration (FHWA) of the United States Department of Transportation (USDOT) to specify the standards by which traffic signs, road surface markings, and signals are designed, installed ...
The CA MUTCD and sign specifications are organized similarly to the MUTCD and SHSM, respectively. Each of the California sign specifications is assigned an alphanumeric designation and organized according to the same series found in the SHSM. The sign designation for a state-specific sign includes a "(CA)" after the sign number.
Stopping sight distance is one of several types of sight distance used in road design. It is a near worst-case distance a vehicle driver needs to be able to see in order to have room to stop before colliding with something in the roadway, such as a pedestrian in a crosswalk, a stopped vehicle, or road debris .
Intersection sight distance is the sight distance needed to safely proceed through an intersection. The distance needed depends on the type of traffic control at the intersection (uncontrolled, yield sign, stop sign or signal), and the maneuver (left turn, right turn, or proceeding straight).
Pursuant to the California Public Records Act (Government Code § 6250 et seq.)

A 1965 law strengthened the MUTCD's legal authority by prohibiting the sale, purchase, or manufacture of noncompliant signs and signals. [4] Further editions were published in 2003, 2005, and 2012 under a shortened title, Ohio Manual of Uniform Traffic Control Devices. The 2012 edition conforms to the 2009 MUTCD. [3]
Stop sign placement can pose difficulties and hazards in applications where cross traffic is not controlled by a sign or light. Relatively long distance between the stop sign and the crossroad facilitates accurate perception of the speed of approaching cross traffic, but lengthens the time and distance required to enter and clear the junction.
