How Long Do Arizona Police Investigate a Hit and Run Before Pressing Charges?

Leaving the scene of an accident is one of the most stressful mistakes a driver can make. Once you drive away, the agonizing wait begins. Every time the doorbell rings or an unknown number calls your phone, you wonder if it is the police. In Arizona, hitting another car or causing an injury and fleeing the scene triggers a criminal investigation under ARS 28-662 or ARS 28-661. While you might hope that the police have better things to do, law enforcement agencies across the state dedicate specialized units to track down fleeing drivers. Understanding how this investigative timeline works, and what your constitutional rights are, is critical.

The Investigative Timeline for a Hit and Run

There is no standard timeline for a hit-and-run investigation. If you side-swiped an empty parked car and no one was around, a patrol officer might spend an hour writing a report and then place the case in an inactive file due to a lack of leads. However, if the accident involved injuries, significant property damage, or road rage, the case will be handed over to a dedicated detective.

For minor property damage cases, investigations usually conclude within 1 to 4 weeks. If the police do not contact you within a month, it is possible the case has stalled. However, in felony cases involving severe bodily injury or death, the Arizona Department of Public Safety Phoenix or local traffic units will keep the case open indefinitely. They will spend months subpoenaing camera footage, analyzing debris, and waiting for crime lab results on paint transfers. In Arizona, the statute of limitations for a misdemeanor hit and run is one year, but for a felony, prosecutors generally have up to seven years to formally press charges.

How Police Use Cameras to Track You Down

The days of getting away with a hit and run simply because there were no human witnesses are over. The modern world is covered in a web of digital surveillance.

Ring Cameras and Residential Surveillance

If you hit a parked car in a residential neighborhood, the first thing responding officers will do is knock on the doors of adjacent houses. Detectives routinely request footage from Ring doorbell cameras, exterior security systems, and even dashcams from other parked vehicles. These high-definition cameras can easily capture the make, model, and often the license plate of the fleeing vehicle.

Traffic Cams and ALPRs in Maricopa and Pima Counties

Major jurisdictions like the Maricopa County Sheriff's Office Phoenix and the Pima County Sheriff's Department Tucson heavily utilize Automated License Plate Readers (ALPRs). These cameras are mounted on traffic lights, police cruisers, and toll booths. If a witness reports that a red Ford F-150 fled the scene, detectives can run that description through the ALPR database to see if a vehicle matching that description passed through a nearby intersection within minutes of the crash.

What Happens if Your Car is Towed for Evidence?

Sometimes, the first sign that you are under investigation is not a knock on the door, but a tow truck showing up at your workplace or home. If police identify your vehicle, they can obtain a search warrant to seize the car. They will tow it to an impound lot to examine the crush damage, measure the height of the impact, and swab for paint transfers to match the victim's vehicle. If your car mysteriously disappears and you find out it was impounded for a hit-and-run hold, you must not contact the police station to ask for it back without an attorney present.

Responding to Detectives at Your Door

Detectives frequently use a tactic known as a "knock and talk." They will arrive at your home unannounced, act friendly, and say they just want to hear "your side of the story" about a recent accident involving a car registered in your name.

The Critical Importance of the 5th Amendment

This is the most crucial moment of the investigation. Police are allowed to lie to you. They may claim they already have you on video, even when they do not. The only thing they need to close the case is for you to admit you were the one driving the car. Under the 5th Amendment of the U.S. Constitution, you have the absolute right to remain silent. You should step outside, close your front door behind you, and politely state: "I decline to answer any questions without my attorney present." Do not offer an alibi, do not admit to being the driver, and do not try to explain away the damage on your bumper. Hand them the business card of your lawyer, and end the conversation.
