If you were able to get the license plate number of the car, you can submit the information to a national database, such as http://reportdangerousdrivers.com/. You can also use an app like Bad Driver. Many local police departments and city transportation departments have online forms where you can report reckless drivers. If they do, fill out their online form.  To find out if this is available in your area, you can search online for the name of your city or county with the words "report reckless driver." For example, you might type the words "Charlotte report reckless driver" or "Orange County report traffic violation." You may need to send an email. In this email, you might write, "I noticed a red Mustang speeding down I-95 this morning around 9:00AM. They were weaving in and out of traffic and nearly collided with a truck. I have attached a photo of their license plate. Thanks." If you know the identity of an unsafe driver, you can request for your local department of motor vehicles to give them a new driving exam. Some departments have online forms for this. You may need to email others. In most cases, this information can be given anonymously. On this form, you should:  Identify who needs to be reexamined. If possible, provide their driver’s license number or their license plate number. Provide a reason why they should be reexamined (medical issue, alcohol problem, declining eyesight, etc.) State your relationship to the driver (family member, friend, court appointed sponsor, etc.) In your email, include as much information as you can about the car. Include its make, model, color, and description. Attach any photos or videos you have of the reckless driving. This will help the government investigate the driver.  In the US, any license plate number beginning with G is owned by the government.  You can email howsmydriving@gsa.gov to report the reckless driver. In Australia, contact your state government. If a police car is the problem, you may want to contact the police department directly to complain.  Canada and the UK do not have specific agencies to report government vehicles to.
