Question: Which colour combination is used for construction zone signs?

Answer options:

  • Yellow and black ✅ Orange and black
  • Red and white
  • Blue and white

Correct answer: Orange and black

Explanation: Under Alberta's Traffic Safety Act guidelines, orange and black is the standard color combination designated for temporary hazard and construction zone signs, alerting drivers to upcoming roadwork and lane changes. Yellow and black signs are incorrect as they indicate permanent physical hazards, while red and white signs are reserved for regulatory actions like stopping, and blue and white signs denote driver services. This standardized color-coding system helps motorists instantly recognize the nature of a road condition ahead. Expect multiple questions on the Alberta Class 7 exam regarding sign shapes and colors, making rapid visual identification a vital test-taking skill.
