Try to plan your visits to automatic teller during the day, rather than after dark. Choose an ATM location that is in a busy public place. Avoid making withdrawals in isolated areas. If at all possible, take along a friend who can watch the surroundings while you are conducting your transactions.
Watch out for suspicious-looking people waiting around an ATM–they may not really be customers. If someone offers to let you go ahead of them, decline politely and leave.
When visiting a drive-through ATM, keep your doors locked and be prepared to drive away quickly. If anyone approaches your car on foot, roll up your window and drive off.
