Riding SEPTA can be either a pleasant experience or nerve-wracking, but following a few unwritten rules can ensure that you are not among those passengers who can turn a regular commute into a nightmare, writes Sandy Smith for Philadelphia Magazine.

When waiting for and boarding trains and buses, make sure to space out instead of crowding near the platform entrance. Stand behind the yellow strip on the platform’s edge at train stations and be sure to step aside and allow people to get off when your train or bus arrives.

Once inside your bus or train, remember that the seats in the front are reserved for older and disabled riders. You also need to learn to recognize seats designated for riders in wheelchairs which are usually not marked but can fold up. These seats should also be given to passengers with babies in strollers.

If you are sitting in an aisle seat move over to the window seat to let another passenger sit down. Do not leave your bag on an empty seat when there are other passengers standing.

Wearing headphones, not smoking, and not standing in door wells are among other unwritten rules that will make everybody’s ride more pleasant.
