Why New York's Taxis Are Yellow

New York's yellow taxis come from a mix of early taxi marketing, visibility logic, and a late-1960s rule meant to separate licensed cabs from illegal street-hail cars.

The yellow taxi is one of New York's clearest visual signals.

You can see one half a block away through rain, steam, scaffolding, bike lanes, pedestrians, delivery trucks, and the moving disorder of an avenue. Before an app tells you a car is coming, before a roof light becomes legible, before you can read a medallion number, the color does the work.

That is why the color matters.

It turns a private car into public infrastructure.

New York taxis were not always yellow. Early automobile cabs in the city wore different colors depending on company, owner, branding, and era. Harry N. Allen's New York Taxicab Company, one of the first major gasoline taxi operators in the city, reportedly used red and green before moving toward yellow for visibility. In Chicago, John D. Hertz built the Yellow Cab Company into a national taxi brand, helping make yellow the color Americans associated with cabs long before every New York taxi was required to wear it.

Hertz's origin story has become taxi folklore.

According to common accounts, Hertz wanted a color that would stand out in traffic and commissioned or relied on visibility research pointing toward yellow. The exact study is harder to pin down than the legend suggests, and Time notes that New York's own yellow lineage also involved Albert Rockwell's Yellow Taxicab Company. But the business logic is straightforward: a taxi company needed its cars to be found quickly by people standing at the curb.

Yellow was advertising at 25 miles per hour.

There is also a human-vision reason the choice feels intuitive. Yellow and yellow-green colors can be highly conspicuous because they stimulate the eye strongly and contrast well against many urban backgrounds. That does not mean yellow is always scientifically superior in every setting. Visibility depends on lighting, context, weather, surrounding colors, and what the viewer expects to see.

Expectation may be the more important part.

Once enough taxi companies used yellow, the color stopped being only visible. It became meaningful. A yellow car was not just easier to notice; it was easier to categorize. On a crowded street, the brain does not want to analyze every sedan. It wants a shortcut. Yellow became the shortcut.

New York eventually turned that shortcut into law.

By the 1960s, the city had a growing problem with unofficial drivers and livery cars picking up passengers on the street. Licensed medallion taxis had the legal right to accept street hails. Other for-hire vehicles were supposed to operate by prearrangement. On the curb, though, that distinction could be hard for riders to read quickly.

So the city standardized the color.

In the late 1960s, New York required medallion taxis to be painted yellow so passengers could tell licensed street-hail cabs apart from other vehicles. The Taxi and Limousine Commission, created in 1971, later became the agency responsible for licensing and regulating yellow medallion taxis, livery vehicles, black cars, commuter vans, and other for-hire services. TLC rules still specify the exterior color for medallion taxicabs as taxi yellow.

The color is tied to the medallion system.

Medallions began in 1937 under the Haas Act, when the city capped the number of taxis allowed to pick up street hails. The goal was to control congestion and stabilize an industry flooded with drivers during the Depression. Over time, the medallion became both a license and an asset. Its value rose, crashed, and became central to one of the city's most painful transportation finance stories.

But visually, the medallion needed a uniform body around it.

The yellow paint made the regulatory category visible. It told passengers: this car is allowed to stop when you raise your hand. It told inspectors and police: this vehicle belongs to the medallion system. It told competitors: this piece of curbside business is legally protected.

That is why yellow cabs feel different from other yellow objects in the city.

They are not just cars painted a bright color. They are moving signs for a specific legal arrangement: street hails, meters, medallions, roof lights, partitions, inspections, driver rules, fares, and city control.

The system has changed around them. Ride-hail apps broke the old monopoly on convenience. Green boro taxis added another street-hail color for parts of the city underserved by yellow cabs. The official taxi design has shifted. The Checker cab disappeared. Hybrids, minivans, wheelchair-accessible vehicles, and app integrations changed what a taxi can look like and how riders use it.

Still, yellow survives because it does the thing New York needs it to do.

It compresses a lot of information into one glance.

In a city where everything competes for attention, the yellow cab is a piece of transportation policy you can see from across the street.
