Regulatory signs are usually ____ and should always be obeyed.
- White ✓
- Blue
- Green
- Orange
Answer: A. White
Regulatory signs are usually white (white with black lettering) and should always be obeyed.
Why this is the answer
The handbook's traffic sign color list puts regulatory signs under white/black. It says these signs control traffic, set limits, or give commands. That matches the question's description of signs you must obey. It also lists blue for driver guidance, green for guide or directional information, and orange for construction and maintenance warning, so none of those is the regulatory color.
Why the other answers are wrong
- B. Blue — Blue is listed for driver guidance, not for the regulatory signs that set limits and give commands.
- C. Green — Green is listed for guide or directional information, not for regulatory commands.
- D. Orange — Orange is listed for construction and maintenance warning, not for regulatory signs.
Remember it
Think white means rules: it tells you what to do, while blue guides, green directs, and orange warns.
