About guide signs
Guide signs are green (directions and distances) or blue (services like gas, food, and hospitals). They don't command an action, but the written test still asks what their colors and symbols mean so you can navigate without hesitation.
Practice the rule this sign carries
The 'Basic Speed Law' means you can be cited for unsafe speed even when:
- A. Driving 5 mph over the limit in clear weather
- B. Driving exactly at the posted speed limit
- C. Driving below the posted speed limit if conditions are hazardous
- D. Driving on a road with no posted speed limit
Show answer
C. Driving below the posted speed limit if conditions are hazardous — The Basic Speed Law requires you to drive at a speed safe for actual conditions — fog, rain, heavy traffic, or road hazards may require driving well below the posted limit. The posted limit is the maximum, not a guaranteed safe speed.
