Why do police officers touch the back of a car?
Should you worry if a cop does this?
You’ve seen it in movies, TV shows, and maybe even in real life: a cop touching the back of a car during a traffic stop. If it’s such a common practice, it must mean something, right? Right! In this article, we’ll teach you why police officers touch the trunk or back taillight before approaching a driver during a traffic stop (plus what you should do if this happens to you).
A cop most likely touches the back of a car to leave proof that they’ve been near the vehicle.
Some officers may tap the top of a trunk to check if it’s closed.
There’s no way for an officer to know exactly how a traffic stop will go. By touching the back of the car before approaching the driver, the officer leaves behind a bit of evidence to say, “I was here.” This way, if the driver fled or harmed the officer, the car could be tied to the crime.
In light of this, a cop may also place a hand on the car's roof while talking to the driver.
Nowadays, dashboard camera footage is used for the majority of evidence in traffic stop incidents, but the practice of placing a fingerprint on a car remains in case technology fails.
There’s no law demanding an officer to leave behind a fingerprint, so it’s up to the precinct, department, or officer’s discretion to do so or not.
To ensure the trunk is closed
Before 2002, car trunks didn’t have a safety latch, which meant that if someone were to hide inside, they would have to keep the trunk propped open to avoid being trapped. Officers would press on the trunk before approaching the driver to make sure they wouldn’t be attacked from behind. If an officer was trained before 2002, they may still touch the trunk of the car out of habit.
Nope, there’s no need to worry if a cop touches the back of your car.
Whether you’re being pulled over or you witness a traffic stop, a police officer means no harm when they touch the trunk or taillight. They’re simply following protocol, ensuring everyone’s safety, and/or sticking to a habit.
You have a right to stay silent and deny a vehicle search unless the officer has probable cause. If you’re arrested or detained, you can ask for a lawyer and remain silent.
If you’re a passenger, you can ask the officer if you’re free to leave (and then do so quietly if you are).
If you believe your rights were violated, write down or document everything you remember about the incident, including the officer (s)’s badge number (s), and then
with the department’s internal affairs division.

Follow the officer’s instructions. If the police officer asks for your license, registration, and proof of insurance, offer it without hesitation. It’s always better to be cooperative, even if you’ve done something wrong, as the situation is more likely to go in your favor if you keep your cool. [6]
