What type of vehicle does a cyclist warning sign typically refer to?

A cyclist warning sign specifically refers to bicycles. This sign is designed to alert motorists and other road users to the presence of cyclists on the roadway, encouraging them to exercise caution and be aware of the potential for bicycles to share the road. Cyclists may be riding alongside or in close proximity to motor vehicles, and increased awareness can help prevent accidents.

The visibility of cyclists can be limited compared to larger vehicles, so the sign serves a vital safety function. It is essential for drivers to differentiate between the types of road users depicted in warning signs to ensure that all parties on the road can act safely and responsibly.
