Make sure the person you meet is who you think they are. Talk on the phone first, preferably with a video call.
Tell a loved one where you're going, how the meeting is going, and when you're coming back so someone knows about you.
Meet somewhere where you feel safe, preferably in a public place, especially on your first date.
Arrange your own transportation. If you still get in someone's car, send a photo of the car number to a friend.
Make sure you have your phone charged. Do not consume alcohol and keep an eye on your glass and personal belongings.
