“Unveiling the Mystery: What Does It Mean When Cops Tap Your Tail Light During a Traffic Stop?”
The Scene of the Crime!

Let’s say an officer pulled someone over and had just tapped the driver’s tail light. However, this driver was dangerous; and it led to an accident with the officer now in a hospital.
Luckily, since the fingerprints were left on the car, the police have evidence that this was the car at the scene of a criminal investigation.
Though Its Not A Sure-Fire Way

However, this fingerprint tactic is not a sure-fire way to gather evidence.
Unfortunately, there is always the possibility that the fingerprints were tampered with or smudged; or washed away by rain or snow.
What’s In The Trunk?

If a police officer believes that they are in a dangerous situation when they pull someone over, they will also touch the trunk to ensure it is latched.
This is to ensure that no one is hiding or going to hop out of the trunk to harm the officer.
Partners Watch Eachother’s Backs

While one officer checks to ensure the trunk is locked, their partner will typically come up and talk to the driver.
This will ensure a dangerous driver does not grab a weapon or get away while the other officer checks the trunk.
Dashcams Deliver Documentation

Of course, the practice of tail light tapping was more vital before technology brought us the dash cam.
