Why this is the answer
The correct answer in the official bank: Beware! Work vehicles and tractors crossing.
The sign warns that a work vehicle or a tractor may cross the road ahead. Because it is a warning sign, it does not prohibit entry, does not require you to stop, and does not set right of way. Slow down, be more alert, and be ready for a slow vehicle entering the road.
