California is one of ten states that publish their own editions of the MUTCD. [1] The CA MUTCD defines the content and placement of traffic signs. Design specifications are detailed on a section of the Caltrans website that is based on the national Standard Highway Signs and Markings (SHSM) document.
ARROW relies on the principle of thin-film interference. It is created by forming a Fabry-Perot cavity in the transverse direction, with cladding layers that function as Fabry-Perot etalons. [1] A Fabry-Perot etalon is in resonance when the light in the layer constructively interferes with itself, resulting in high transmission.
Locomotives are painted light gray, with a blue stripe (darker than Phases I–III, but lighter than IV) at the top and a thin red reflective sill stripe at the bottom. The blue stripe has a wavy bottom on Genesis locomotives and Acela Express power cars, and a flat bottom on other locomotives and ex- F40PH non-powered control units (NPCUs).

Youth participate in Cub Scouting from age 5 to 10, working through Lion, Bobcat, Tiger, Wolf, Bear, Webelos, and Arrow of Light. [ 3 ] In addition to the Adventures used to earn promotion, Cub Scouts can work to earn multiple other individual awards though participation in special programs, many of which happen during the summer time.
In New Zealand, where traffic is on the left, when a road is given a green light from an all-direction stop, a red arrow can continue to display to turning traffic, holding traffic back while a pedestrian crossing on the side road is given a green signal (for left turns) or while oncoming traffic goes straight ahead and there is no permissive right turn allowed (for right turns).

A Morse code light is light in which appearances of light of two clearly different durations (dots and dashes) are grouped to represent a character or characters in the Morse Code. For example, "Mo(A)" is a light in which in each period light is shown for a short period (dot) followed by a long period (dash), the Morse Code for "A".
