Texas Car / Permit practice question · Road Signs

White rectangular signs with black or red lettering usually give you:

Answer choices

• a warning about a curve ahead
• directions to the nearest hospital
• a traffic law or rule you must obey, such as a speed limit— Correct answer
• the distance to the next exit

Why this is the answer

Regulatory signs tell you what you must or must not do, and you have to obey them just as you would a traffic law. They are generally vertical rectangles, and white and black are both regulation colors. Warnings about a curve belong on yellow diamond signs, while directions to services and exits appear on guide signs.
