Penndot pub380 calls out that bikes can.

(EDIT: And that vehicle code explicitly calls out motorcycles, which bicycles are not)

Chapter nine has a whole section on it.

>GETTING THROUGH TRAFFIC JAMS
Traffic jams do not have to stop you—that is one of the biggest ad - van tages of bicycling in the city. However, in the tight quarters of a tie-up, take extra care. Stopped cars in a traffic jam present the same hazards as parked cars: blindspots, doors and unpredictable starts and turns.
If there is an open passing lane, use it rather than thread between cars. If the street is completely plugged, pick your way forward slowly and with your hands on the brake levers. Remember, any car door could open!
If you are in a traffic jam, you can be sure that the cars will not move, since they have nowhere to go. However, if there is an open driveway or parking space into which a car could turn, you have to assume that it will. Look to see whether the car's front wheels are turned. Move away from the side of the car as you pass, and try to get the driver's attention as you approach the front of the car.
When cars are stopped, but not completely bumper to bumper, be very wary of cars from other lanes cutting across in the gaps. Stop and look before you move out into a gap. Be especially careful if the vehicle you are passing, like many vans, does not have a hood you can see over.
