What does merging into the bicycle lane before turning right ensure?

Merging into the bicycle lane before turning right is primarily intended to protect cyclists. By doing so, a motorist creates a safer environment for those on bicycles, as it reduces the likelihood of a collision during the turn. When a vehicle merges into the bicycle lane, it alerts cyclists to the driver's intention to turn, allowing them to anticipate and react accordingly. This practice is essential in promoting safer interactions between motor vehicles and bicycles, thus encouraging a shared road space that prioritizes the safety of all users.

In terms of the context of the other responses, while making turns faster or avoiding traffic delays may be outcomes of efficient driving habits, they do not address the critical aspect of safety for cyclists. Legal requirements regarding merging might vary by jurisdiction, but the focus should always be on ensuring the well-being of all roadway users. Hence, protecting cyclists is the most relevant reason for this practice.
