On a breezy day in Manchester, New Hampshire, Mateo and his wife, Lisa, decided to run an errand.
As the couple rode down an interstate highway on July 31, 2017, they came upon a police vehicle on the shoulder with its lights flashing.
Under New Hampshire traffic laws, drivers must slow to a safe speed and 鈥溾 to stationary emergency vehicles with flashing lights.
But Mateo, 36, did not know this.
