ORLANDO, Fla. – If you’ve ever seen a police car with its lights “glowing,” but not flashing or accompanied by a siren, you’re not alone in wondering what it means—and whether you need to move out of the way.

It’s a common point of confusion on the road, especially as law enforcement lighting technology continues to evolve.

Years ago, police vehicles were typically equipped with a single rotating light. That iconic look has given way to complex lighting systems, which now include a variety of patterns and modes.

One of those modes is known in the field as a “steady patrol burn” — when the vehicle’s emergency lights are on, but they are not flashing rapidly and there is no siren.

Why use steady burn lights?

The steady burn mode serves several purposes:

• Visibility: It helps law enforcement officers stay visible to the public, especially at night or in high-traffic areas.

• Crime deterrence: A glowing presence can discourage criminal activity in certain neighborhoods or hot spots.

• Scene management: At certain scenes, especially those that are stable or calming down, steady lights can create a less chaotic visual environment than rapidly flashing lights.

Do you have to move?

If you see a police car with glowing or steady-burning lights, you are not required to move out of the way. These lights signal presence, not an active emergency response.

However, once those lights begin flashing in a rapid pattern and you hear a siren, that’s your cue to safely pull over or yield. The vehicle is now in emergency mode, responding to a call or needing clear passage.

Know the difference

As always, when in doubt, it’s a good idea to safely yield if a vehicle behind you seems to be signaling a need to pass.

But just remember that not every lit-up police car is on an urgent call.
