Unit 04, Lesson 01 - Signs, Signals, Color, and Shape

04.01 Signs, Signals, Color, and Shape

The use of signs, signals and pavement markings is an effective method of indicating right-of-way, direction of flow, and warnings of dangerous conditions.

In this country, widespread changes in highway and street traffic signs have occurred which affect every motorist and pedestrian. The United States has adopted an international-type system of traffic control devices which uses pictures rather than written messages. Understanding these signs is required for you to take advantage of necessary road information. All signs in Utah are placed in accordance with the manual on uniform traffic control devices.

Color and Shape of Signs
If you can readily recognize the general type of a sign, you will be a better-prepared driver. One indication of the meaning of an upcoming sign is its color. Some of the colors used on traffic signs are:

Red - can mean two things. It can indicate times when you must stop, and it can also show times when certain traffic movements are not allowed.
Black on White - used for signs involving specific traffic laws. Speed limits and parking signs are good examples of how this regulatory color combination is used.
Yellow - indicates conditions under which extra caution must be used.
Orange - for highway construction and maintenance. Workers are usually present, be alert, expect delays and possible sudden stops.
Blue - indicates services available.
Brown - indicates state or federal parks.
Green - indicates guidance such as exits or business loops.

Skill Builder - Traffic Lanes, Road Signs, Speed Limits

The links in this activity were developed by the state of California to help drivers develop proper driving habits. They are all "YouTube" videos, so if your school blocks access to Youtube.com, then you will have to watch the videos at another location. (library, home, GoogleTV, AppleTV, etc). They are short and contain very good information on the driving task. Please watch all the videos carefully. It may be necessary to watch them a couple of times to understand the information so you will clearly understand it before you start your behind the wheel driving experience.
