What sign alerts you to possible hazards and road conditions?

• A. Detour sign
• B. Warning sign
• C. Construction sign
• D. Speed limit sign

Answer: (B)

Warning signs are what alert you to hazards and changes in the road ahead. They’re placed to make you slow down, be prepared for a turn or other condition, and adjust your driving accordingly. The key idea is that these signs warn about what could be dangerous or difficult on the upcoming stretch, so you can react in time.

Detour signs indicate you must take an alternate route, usually because of a blockage ahead. Construction signs mark a work zone and may require slower speeds or lane changes. Speed limit signs set the maximum legal speed, not necessarily a warning of a hazard.
