What does the sign 'bicyclist ahead' indicate?

Answer: B — Bicyclist ahead

Warning signs alert you to hazards ahead, so you adjust speed and driving accordingly. A sign showing a bicycle symbolizes that a bicyclist may be on or entering the roadway ahead. Slow down, stay alert for a rider who could move unexpectedly, and pass only when it’s safe with ample space. This helps protect cyclists and reduces the chance of a collision. Pedestrian crossing ahead would show a person walking or a crosswalk symbol, road work ahead would display a construction icon, and a sign about merging with a bicycle lane would indicate a lane change or bike-lane information. These depict different situations, so they’re not what this sign conveys.
