Here's a handy link you may want to check out. It links to
Buffalo area bicycle maps, issued by the Greater Buffalo-Niagara Regional Transportation Council. It includes excerpts of NYS law, plus advice on riding a bike, including:
Turning Left-2 Options
1. As A VEHICLE: Signal your intentions in advance. Move to the left turning lane, and complete the turn when it is safe.
2. AS A PEDESTRIAN: Ride to the far crosswalk, dismount & walk across.
Obey All Traffic Signs and Signals*
Bicyclists must obey all local and state Traffic Rules. Bicyclists have the same rights, privileges and duties as other vehicles. Bicycles must be driven like other vehicles if they are to be taken seriously by motorists.
