Do Blue Uber Sign Violates Florida Section316.2397?

Many Uber drivers assume that displaying an illuminated Uber sign on the dashboard helps passengers identify their vehicle and improves safety. However, a recent Florida appellate court decision confirms that using certain illuminated Uber signs—especially blue ones—can give law enforcement a lawful reason to conduct a traffic stop.

In a decision issued on June 10, 2026, the Second District Court of Appeal held that an Uber driver violated Florida Statute § 316.2397 by driving with an illuminated blue Uber sign displayed on the dashboard. The appellate court ruled that the officer had probable cause to stop the vehicle, and that stop ultimately led to the discovery of drugs and a criminal prosecution.

Cadet v. State, ___ So. 3d ___ (Fla. 2d DCA 2026) was decided on June 10, 2026 in Case No. 2D2025-0761. In that case, the driver was operating a vehicle with an illuminated blue Uber sign mounted on the dashboard. A police officer observed the sign and conducted a traffic stop for a suspected violation of Florida’s restrictions on blue lights.

During the stop, officers claimed to smell marijuana and searched the vehicle. The search resulted in the discovery of fentanyl and cocaine. The driver later challenged the legality of the traffic stop, arguing that the Uber sign did not violate the statute. The driver lost that motion to suppress before the Honorable Stephen Mathew Whyte, Circuit Court Judge for Manatee County.

After losing the motion to suppress, the driver pled “no contest” to trafficking in fentanyl and possessing cocaine with intent to sell and was sentenced to eight years in prison.

During the plea, the driver specifically preserved the dispositive nature of the motion to suppress and filed an appeal to challenge the trial court’s ruling.

The appellate court upheld the trial court’s ruling and concluded the traffic stop was legal because the illuminated Uber sign qualified as a “device” displaying blue light. As such, it the Uber light violated Florida Statute § 316.2397. Because the violation was the basis of the stop, the court found the officer had an objectively reasonable basis to initiate the traffic stop.

Requirements of Florida Statute § 316.2397

Florida law contains strict limitations on the use of certain colored lights on vehicles. Section 316.2397 provides in part:

A person may not drive a vehicle upon any highway within this state with any lamp or device displaying a blue light visible from directly in front of the vehicle.

The statute goes even further by expressly stating:

It is prohibited for any vehicle, except police vehicles, to show or display blue lights.

The law contains various exceptions for certain emergency and governmental vehicles. However, none of those exceptions apply to Uber drivers, Lyft drivers, taxi drivers, delivery drivers, or other private motorists.

Why the Court Rejected the Uber Driver’s Safety Argument

The driver argued that the illuminated Uber sign served a legitimate purpose by helping passengers identify their rideshare vehicle. She also argued that the sign was not really a “lamp” or vehicle light.

The appellate court was not persuaded. Instead, the appellate court focused on the plain language of the statute. Even if the sign was not technically a lamp, it was unquestionably a “device” that displayed blue light. The judges explained that the statute broadly prohibits devices showing blue lights and does not create an exception for rideshare companies.

The court emphasized that policy arguments about passenger safety are matters for the Florida Legislature, not the courts.

Why This Matters to Uber Drivers

Many Uber drivers purchase aftermarket illuminated signs online. Some of these signs use blue LED lighting because it is highly visible at night and resembles Uber’s branding. After the Cadet decision, drivers should understand that an illuminated blue Uber sign can provide law enforcement with probable cause for a traffic stop.

Even if the driver ultimately receives only a traffic citation—or no citation at all—the stop itself may still be lawful. That means officers may have an opportunity to:

• Request a driver’s license and registration;
• Check for outstanding warrants;
• Investigate impaired driving;
• Observe evidence of other offenses;
• Develop probable cause for additional searches or arrests.

For drivers carrying firearms, prescription medications, cash, cryptocurrency-related evidence, or anything else that could attract police attention, avoiding unnecessary traffic stops should be a priority.

What About Other Colors for the Uber Sign?

The Cadet decision specifically addressed a “blue” illuminated Uber sign. Florida law treats blue lights particularly harshly because blue lights are generally reserved for law enforcement vehicles. Whether another color would violate the statute depends on the specific facts and the particular provisions of Florida’s vehicle equipment laws.

Drivers should carefully review any illuminated signage before placing it in a vehicle. Nothing in the decision prohibits a driver from displaying a non-illuminated Uber sign. The problem arises when the sign emits blue light that is visible from the front of the vehicle.

Uber drivers who want to identify themselves to passengers may wish to use:

• Non-illuminated Uber placards;
• Window decals;
• Passenger verification through the Uber app; and/or
• Other methods that do not involve blue lights visible from outside the vehicle.

Conclusion

The Second District Court of Appeal has now made it clear that an illuminated blue Uber sign can violate Florida Statute § 316.2397. Uber drivers who continue using these signs risk being stopped by law enforcement even if they are otherwise driving lawfully.

A simple dashboard sign may seem harmless, but under Florida law it can provide officers with a valid legal basis to initiate a traffic stop. For that reason, rideshare drivers should think twice before displaying any illuminated blue Uber sign in their vehicle.

If you were stopped after displaying an Uber sign or any other vehicle equipment that allegedly violated Florida law, consult with an experienced criminal defense attorney to evaluate whether the stop, detention, search, or arrest complied with constitutional requirements.
