Sign shapes, colors and pavement markings

Key points

1. Sign shapes and colors have meaning, so you should recognize a sign even when fog, rain, snow or darkness hides the letters.

   “The shape and color of signs have meaning. If fading light, fog, rain, snow, or darkness make it difficult to see the letters, applicants should still know how to recognize a sign and respond accordingly.”

2. Square and rectangular signs show traffic regulations and guide your speed and direction.

Recognize these signs

3 questions from the West Virginia practice test

1. 1. What do the shape and color of signs help drivers recognize?

   1. Whether the vehicle needs an inspection
   2. The exact distance to the next town
   3. What a sign is trying to tell them
   4. The driver's license renewal date
   Show answer

   What a sign is trying to tell them. The handbook treats sign shape and color as recognition aids that communicate a sign's purpose. This lets a driver begin responding even when lettering is hard to read. The choice “The exact distance to the next town” invents a destination detail, while inspection and license information are unrelated to traffic sign design. Shapes distinguish warnings, controls, and guidance, and colors reinforce those categories. Use the visible outline and color as an early cue, then read the wording or symbol when conditions allow. This is especially useful in fog, rain, snow, darkness, or fading light.

2. 2. What information do square and rectangular traffic signs generally provide?

   1. A guarantee that the lane ahead is free of hazards
   2. A warning that a train is approaching the crossing
   3. Traffic regulations and guidance about speed or direction
   4. A marker showing only the name of a nearby town
   Show answer

   Traffic regulations and guidance about speed or direction. Square and rectangular signs are used to show traffic regulations and guide a driver's speed and direction. They can communicate speed limits, lane directions, or other road rules. The circular or crossbuck railroad signs serve a different purpose, while a guide sign can identify a place without defining all traffic requirements. No sign shape guarantees that a roadway is hazard-free. Read the words and symbols, then combine the instruction with the actual traffic and road conditions around the vehicle.

3. 3. What does a red diagonal bar on a regulatory sign communicate?

   1. Railroad crossing ahead
   2. Complete stop at every intersection
   3. School zone ahead
   4. No or prohibited
   Show answer

   No or prohibited. A red outline with a diagonal bar through a sign means “NO,” or that the pictured action is prohibited. The marking does not automatically mean a complete stop, which is conveyed by the octagonal stop sign. A school zone uses a pentagon warning sign, while a railroad crossing has its own warning shapes and signals. Read the symbol inside the red bar to identify the movement that is forbidden. The practical cue is the diagonal bar: it changes the pictured action from something permitted into something the driver must not do.
