You are driving on a multi-lane municipal road and a bicyclist ahead of you on the right side of the road is signaling to change lanes to the left. You should: a. Slow down if it is safe to do so, and let the bicyclist move left in front of you. They are entitled to use the full left lane if they are turning left.
b. Speed up to pass the bicyclist quickly, and let them change lanes behind you.
c. Maintain your speed, pass the bicyclist with caution, and let them change lanes behind you.
