When is it permissible to drive in a bike lane?

Driving in a bike lane is permissible when making a turn, provided that you yield to any cyclists present. This is because bike lanes are designated areas for cyclists, ensuring their safety and promoting an efficient flow of both bicycle and vehicle traffic. When you are preparing to turn, it's important to use the bike lane briefly to position your vehicle safely while ensuring that you do not disrupt or endanger cyclists. Yielding to cyclists means checking for their presence and allowing them to pass before completing your turn.

In contrast, other options suggest either unlimited use of bike lanes or inappropriate circumstances for driving in them. For instance, using a bike lane during traffic jams, when there is no turn involved, would violate the intended purpose of the lane and could put cyclists at risk. Emergency driving is typically restricted to certain situations that require immediate action, and merely wanting to use the lane at any time disregards traffic laws meant to protect vulnerable road users.
