What action can cyclists take in a substandard lane?”

In a substandard lane, cyclists can ride two abreast. This means that they can ride side by side within the lane, which is particularly relevant in situations where the lane is too narrow for a motor vehicle to safely pass a cyclist without crossing into another lane. Riding two abreast increases visibility and allows for more stable positioning on the road. It can be a way for cyclists to assert their presence and encourage safe passing by motorists.

Cyclists also need to be mindful of traffic conditions and the behavior of surrounding vehicles when choosing to ride in this manner. Riding two abreast is permitted in many places unless local laws state otherwise, so it is important for cyclists to understand their own jurisdiction's rules regarding lane use to stay safe and compliant.
