Accident Alert
Accident Alert is a protocol that law enforcement agencies enact when a winter storm causes so many accidents it has the potential to overwhelm the police force. When Accident Alert is active, it's made known by the broadcast media. Under Accident Alert, police will not respond to minor accidents that involve only minor property damage. If you're involved in a minor accident that has no injuries during Accident Alert, exchange information at the scene and then report it to the necessary police agency within a day or two. Don't bother waiting for the cops to show up.
