On Commerce between W. Ponce and Clairmont Ave. The lane dividers (white paint stripes) are nearly invisible on both sides of the road. Cars turning left onto Commerce from Ponce don't know where the lanes are and often wind up driving in both causing dangerous conditions. Also, there needs to be more advanced warning that the inside line going to Clairmont will turn into a left turn only. Drivers are being caught off guard as they approach Clairmont causing them to stop and try to merge right in a hurry.
