Police response to false 911 calls has increased dramatically since April 1st. This can be attributed to the new ten-digit dialing in the Triangle, as '911' is easy to misdial instead of '919'. If you dial 911 in error, do not hang up. Stay on the line to let the dispatcher know that you dialed the number accidentally. If you hang up, an officer is likely to be dispatched to ensure that there is not a problem, which delays response to actual emergency calls.
