On the ramp exiting the Mass Pike at the traffic light that merges with Washington Street, right turns are allowed on red from the right-hand lane. In practice, though, cars turn right on red from *both* lanes. I've observed cars honk at others in the left lane at red lights because they are not turning through the red light. Please update the signage to reflect common practice - or enforce what is actually permitted here.
