Your Guide to Reporting Dangerous Drivers on California Roads

Why Reporting Matters for New Drivers

As a new driver, you want to feel confident and safe behind the wheel. But what happens when you encounter someone driving so recklessly it makes your heart race? It's unsettling—and it can be dangerous. The good news is, you have the power to take action. Reporting dangerous drivers helps protect not just you, but everyone on the road. This guide walks you through exactly how to do it, step by step.

What Counts as Aggressive Driving in California

Aggressive driving isn't just someone having a bad day. California law defines it as two or more traffic violations that could endanger people or property. Think of it as a pattern of unsafe behavior, not just a one-time mistake. Road rage takes it further—turning driving aggression into a criminal act.

Here are common aggressive driving behaviors to watch for:

  • Excessive speeding that goes far beyond the limit and endangers others.

  • Tailgating with the intent to intimidate.

  • Weaving through traffic or changing lanes without signaling.

  • Running red lights or stop signs deliberately.

  • Improper passing, such as in no-passing zones or on shoulders.

  • Brake checking to retaliate against tailgaters.

When you recognize these behaviors, you're seeing more than just bad manners—you're witnessing actions that put lives at risk. Understanding these 7 shocking road rage statistics can help you grasp just how serious aggressive driving has become on American roads.

When You Should Report a Dangerous Driver

Your safety always comes first. If you're driving, only report once you're in a safe position or have a passenger who can help. There are two main situations where reporting is appropriate:

Emergencies (Call 911):

  • The driver appears intoxicated.

  • There's road rage or threats involved.

  • The driver is going the wrong way.

  • A crash has occurred or nearly occurred.

  • The driving is so reckless that a crash seems likely.

Non-Emergencies (After You're Safe):

  • The driver's behavior was dangerous, but they've left the scene.

  • You witnessed repeated tailgating or unsafe lane changes.

It's worth noting that certain times are inherently more dangerous for driving. Being aware of the most dangerous times for driving can help you stay extra vigilant during high-risk periods.

How to Report Aggressive Driving in California

You have three main options, depending on the situation:

911 for Immediate Danger

  • Pull over safely before calling.

  • Provide your exact location (highway number, direction, exits).

  • Describe the vehicle (make, model, color, plate if possible).

  • Explain what the driver did.

CHP Non-Emergency Line: 1-800-TELL-CHP

  • Use this if the driver is no longer a threat.

  • Give the same details as you would in a 911 call.

  • Reports help CHP track problem areas and deploy patrols accordingly.

DMV Driver Reexamination Request (Form DS 699)

  • Use this for long-term unsafe drivers (elderly or medically unfit).

  • Complete the form with specific examples.

  • Your name is required but can be kept confidential.

What You Need to Report

When you're ready to report, gather the following details:

  • License plate number (even partial helps).

  • Make, model, and color of the vehicle.

  • Exact location, direction of travel, and time of incident.

  • Specific description of what happened.

  • Driver description, if you can get one safely.

Even If You're Nervous About Reporting...

It's normal to hesitate. But remember:

  • Even if you think it's "not that serious," your report could prevent a crash.

  • Even if you didn't get the full license plate, other details still help.

  • Even if you feel unsure, it's better to speak up than stay silent.

Safety Tips Especially for Teen Drivers

  • Never confront aggressive drivers.

  • Let them pass safely.

  • Create space when someone is driving unpredictably.

  • Use passengers to help you report.

  • Don't share personal info with other drivers.

  • If you feel targeted, drive to a safe public place and call 911.

Learning 4 smart ways to de-escalate road rage can be invaluable when you encounter aggressive drivers. Additionally, understanding road rage prevention tips will help you avoid becoming part of the problem yourself.

For drivers in urban areas, mastering driving safety tips for big cities is essential, as city driving presents unique challenges and higher rates of aggressive behavior.

What to Expect After Reporting

You may not see the outcome, but your report matters. Officers may respond in real time or track patterns over time. The DMV may retest a dangerous driver. You won't usually receive updates, but your role as a safe, proactive driver helps build a culture of accountability.

Understanding how to handle dangerous driving situations goes beyond just reporting—it includes knowing what to do when you're the one facing a mechanical emergency or unexpected road hazard.

Own Your Role in Road Safety

Reporting isn't about getting someone in trouble—it's about protecting lives. As a new driver, knowing how and when to report empowers you to act with maturity and confidence. You're not just learning how to drive—you're learning how to lead by example. And that makes the road safer for everyone.

During high-risk periods like summer vacation, when families take more road trips, it's especially important for parents to review summer driving habits and ensure teenage drivers are prepared for the increased dangers they'll face on the road.

Remember, developing strong defensive driving skills and understanding your responsibilities as a driver are just as important as knowing how to report dangerous behavior. Taking these steps seriously from the beginning of your driving journey will help create safer roads for everyone.
