What to do if a stranger asks you for a ride? Even if it's something you really want, if the offer is coming from a stranger, you should ignore the person and walk the other way. If a stranger walks up or pulls up in a car and you're too far away to hear the person, don't go closer, even if the person waves you over. Just get away.
What to do if someone offers you a ride?
