Where to report a bad driver
You can report a dangerous driver to your local police department's non-emergency line. Most departments have a phone number for reports that do not require an when ready response — this is different from 911, which is for active emergencies. When you call, have the license plate number ready, along with the date, time, location, and a description of what happened.
Some police departments also accept reports through their website or a dedicated online form. A few larger cities have apps or text-based reporting systems. Start by searching "[your city] police report dangerous driver" or calling the non-emergency number listed on your local police department's website.
If the dangerous driving happened on a highway, you can report it to the state police or highway patrol instead. Their non-emergency lines are usually listed on your state's transportation or public safety website.
Key Takeaways
- Call your local police department's non-emergency line, not 911, to report reckless or dangerous driving that is not an active emergency.
- Have the license plate number, date, time, location, and a description of the dangerous behavior ready when you report.
- Some police departments accept reports online or through an app, so check your local department's website for options.
- Highway or interstate incidents should be reported to state police or highway patrol instead of local police.
- Police cannot always identify or contact a driver based only on a license plate, so detailed information about the incident strengthens your report.
What information police need from you
The license plate number is a starting point, but police need more to investigate. Write down or remember the date and time of the incident, the exact location or street where it happened, and the direction the vehicle was heading. If you can describe the vehicle itself — color, make, model, size — that helps confirm you are reporting the right car.
Describe the dangerous behavior specifically. Instead of "reckless driving," say what you saw: "The driver cut across three lanes without signaling at 2:15 p.m. on Route 9, nearly hitting a blue sedan." The more concrete your description, the more useful your report is to police.
If there were witnesses, note that. If you have a photo or video of the incident, mention it when you call — some departments will ask you to send it or bring it in.
What happens after you report
Police will log your report, but they cannot always track down the driver or take action. A license plate leads to a vehicle owner's name and address, but not necessarily to who was driving at that moment. If the owner is the driver, police may contact them. If the owner was not driving, the investigation often stops there.
Police are more likely to follow up if you report a pattern of dangerous driving from the same vehicle, or if the incident caused an accident or injury. A single report of aggressive driving, even with a license plate, may not result in a visible consequence.
You will not usually hear back about the outcome of your report. Police departments do not typically notify the person who reported to say whether they contacted the driver or took any action.
When to call 911 instead of the non-emergency line
Use 911 if the dangerous driving is happening right now and poses an when ready threat to safety — for example, if a driver is swerving across lanes at high speed, driving the wrong way on a highway, or has just hit another car. Tell the dispatcher the location, direction of travel, license plate, and vehicle description so police can respond while the driver is still in the area.
After an accident, call 911 if anyone is injured or if there is significant property damage. The police report filed at the scene creates an official record that insurance companies and courts can use.
Reporting to your state's transportation department
Some states have a separate system for reporting dangerous drivers to the Department of Transportation or a highway safety office, usually for incidents on state highways or interstates. These reports go into a database that may be reviewed for patterns of dangerous behavior by the same driver.
Check your state's DOT or highway safety website to see if this option exists. The process is similar to reporting to police — you provide the license plate, date, time, location, and description of the incident. These reports are typically reviewed by state police or highway patrol.
What you cannot do with a license plate alone
You cannot look up a driver's personal information using only their license plate. That information is private and protected by law. You also cannot contact the vehicle owner directly to confront them about their driving — that can escalate into conflict and is not safe.
Do not post the license plate on social media or a public forum asking others to identify the driver. This can lead to harassment of an innocent person if the plate number is misread or if the wrong vehicle is targeted.
If you were in an accident with the vehicle, you can exchange information with the driver at the scene or file a police report. If you were not involved in an accident, reporting to police is the appropriate channel.
Documenting the incident for your own records
If you witness dangerous driving, write down what happened as soon as it is safe to do so. Include the date, time, location, license plate, vehicle description, and exactly what the driver did. If you took a photo or video, save it with the date and location information.
Keep this record even if you do not report it when ready. If the same driver is involved in an accident later and police investigate, your documentation may be useful. If you are ever asked to describe the incident in court or to an insurance company, your notes will help you remember details accurately.
Frequently Asked Questions
Can I report a driver anonymously?
Yes. When you call the non-emergency line, you can give your report without providing your name or contact information. Some online reporting systems also allow anonymous submission. Police will still log and investigate the report, though they may have fewer options for follow-up without a way to contact you if they need more details.
What if I only have a partial license plate number?
Report what you have. A partial plate is less useful than a full one, but combined with a detailed vehicle description, time, location, and description of the incident, it gives police something to work with. Be clear about which digits or letters you are certain of and which you are unsure about.
Will the driver know who reported them?
Not from the police report itself. Police do not tell a driver who made a report about them. However, if the incident led to an accident and both drivers exchanged information, the other driver would know you reported them if you told them you were going to.
Can I report a driver for being slow or annoying?
Police focus on dangerous behavior — speeding, reckless lane changes, running red lights, aggressive honking, tailgating, or driving under the influence. Slow driving or minor annoyances are not typically something police will investigate, unless the slow driving is so extreme that it creates a hazard.
What if the same driver keeps doing this?
Report each incident separately with the date and time. If you report the same license plate multiple times, police may recognize a pattern and be more likely to investigate or contact the driver. Mention in your report if you have seen this vehicle driving dangerously before.
