From Pennsylvania Driver's Manual
When there is a STEADY RED LIGHT, you must stop before crossing the marked stop line or
crosswalk. If you do not see any lines, stop before entering the intersection. Wait for a green light before you start.
You may turn right while the light is red, unless a NO TURN ON RED sign is posted at the intersection.
You must first stop, check for and yield to pedestrians and other traffic.
You may also turn left after you stop at a red light, if you are in the left lane and are turning left from a one-way street onto another one-way street, unless a sign tells you not to turn. You must first stop and yield to pedestrians and other traffic.
Although not common in Pennsylvania, a RED ARROW is used in other states. It means you may not turn in the direction the arrow points.
The sign you posted:
RIGHT TURN SIGNAL
This sign is posted close to a traffic signal to indicate that the signal controls right turn movements.
In practice this usually means that there are situations when it is possible to turn right but not go straight.
There is also DMV Guide to Young Drivers which states:
Making right turns at intersections with lights or signs:
- Even when the light is green, look out for traffic turning left
from the oncoming lane.
- Unless there’s a sign that says “No Turn on Red,” in
Pennsylvania it’s legal to turn right even on a red light after
coming to a complete stop – but only if there’s no traffic coming
from the left or across the street, or pedestrians in
So if you need to make a right turn on Red and there are no specific prohibitions you can do it in PA.
