Yellow, diamond-shaped signs are warning signs. The tractor symbol specifically warns drivers to expect slow-moving farm machinery on the road, requiring caution.

Why the other options are wrong

  • A. Detour signs are often orange or black and white, not yellow diamond with a tractor symbol.
  • C. Roadside market signs are typically guide signs, not warning signs, and don't use this symbol.
  • D. Parking signs are typically white rectangular regulatory signs.
