When is it permissible to enter a bike lane?

Entering a bike lane is permissible when preparing to turn because doing so is essential for ensuring the safety of both cyclists and drivers. A driver preparing to make a turn must merge into the bike lane to position themselves appropriately for the upcoming maneuver. This helps in communicating the driver's intention to turn, allowing cyclists to take necessary precautions.

When preparing to turn, it is required to signal and check for any approaching cyclists. This ensures that the turn is made safely without impeding the flow of bicycle traffic. This rule exists to maintain order and safety on the road, providing a clear understanding that a driver is about to turn and allowing cyclists the chance to react accordingly. Proper use of the bike lane in this instance facilitates smooth traffic flow and minimizes the risk of collisions.
