Getting a speeding ticket in the State of New York can be a traumatic – and expensive – experience.
Drivers convicted of speeding often face penalties and fines, and repeated or excessive offenses can result in the loss of a license. But in some places in New York State, drivers issued a speeding ticket may see a very different outcome than one would typically expect: a smaller fine, the avoidance of long-term penalties, and – oddly enough – additional money in local government coffers.
Last year, I wrote a post detailing some data science techniques that used a data set from the State of New York on traffic violations. This is an incredibly rich data set and it’s awesome that the state makes this available as open data. However, the issuance of traffic tickets only tells part of a larger story – since the release of this initial data set, the state has now released data on traffic ticket convictions. Comparing both of these data sets allows us to see the full picture of what happens when a traffic ticket is issued in the State of New York, from issuance all the way through to adjudication.
An examination of these data sets show that – in certain areas of the state – tickets issued for speeding are much more likely to be negotiated down to a lessor offense that allows drivers to avoid a penalty from the Department of Motor Vehicles (DMV), and actually provides a backdoor benefit for local governments.
