Students are heading back to school, and people are heading back to work.

The transit system will be busier than ever, and Transit Police have some tips on how to stay safe.

Among the advice: resist the temptation to listen to your IPod while on transit.

Police say the distraction could make you a potential target.

Any electronic devices should be stored out of site, and keep your wits about you, especially if you're standing near doors.

Speaking of doors: don't block the doors on Skytrain.

Some people tend to do that.

And holding those doors open for too long could trigger a system wide shutdown.
