What do blue signs with white lettering typically indicate?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

Motorist services such as gas, food, lodging, and hospitals

  1. A No-passing zones
  2. B Motorist services such as gas, food, lodging, and hospitals
  3. C Speed limits
  4. D Hazards ahead

Why this is the answer

Blue signs with white lettering are guide signs that indicate motorist services and information — such as gas stations, food, lodging, rest areas, and hospitals — often near highway exits. The blue color is reserved for these service-related guide signs, helping travelers find what they need. Brown signs, by contrast, mark recreational and cultural points of interest (parks, historic sites), and green signs give directional and distance information. Distinguishing the guide-sign colors (green for directions, blue for services, brown for recreation) rounds out a driver's understanding of the informational signs on the road.
