What must you anticipate with this road sign?

You answered correctly because this road sign warns that you may encounter multiple hazards related to nearby trees. Firstly, branches or foliage might protrude into the roadway, which could reduce the space you have to drive safely. Secondly, broken branches or twigs could be lying on the road, making the surface uneven or slippery. Lastly, drivers might swerve suddenly to avoid these obstacles or because their view is blocked by the trees. Therefore, you should drive carefully, watch for obstacles, and be prepared for unpredictable movements from other vehicles when you see this sign.
