Our taxis are smoking free, as mandated by Colorado law.

We Abide by the Following Colorado Laws:

Drivers must accept, and transport where directed, any orderly person/party unless previously engaged. A taxicab may not carry more passengers than the vehicle is designed to seat. Drivers may refuse to transport freight or animals, except service animals (any guide dog, signal dog or other animal trained to work or perform tasks for a person with a disability).

About Us


Boulder Yellow Cab was founded in Boulder in 1924. It is one of the oldest Yellow Cab services in the US and Boulder’s oldest and largest taxicab company, completing approximately 200,000 passenger trips annually with a fleet of over 50 vehicles. Our taxi service operates 24 hours a day, seven days a week, 365 days a year. We are constantly working to ensure that our drivers have the finest tools available in order to provide the best and most punctual service possible.

Over the years, we have been a pioneer in many areas including the first to implement Dispatch radio, GPS dispatch and other communications-oriented technologies and the first to introduce “green” fueled vehicles with Toyota Prius Hybrids and propane-powered Crown Victoria’s. We have been a committed partner to the City and County of Boulder in its growth and development, and are very proud to serve Boulder and the surrounding towns.

We also offer service to the disabled community and the elderly in partnership with city paratransit services, Medicaid and other entities in the healthcare field.

Yellow Cab is owned by Veolia Transportation, a leader in providing transportation
services – including bus, rail, paratransit, shuttle, sedan and taxi – in 200 locations in the US and Canada. Veolia Transportation is the largest operator of taxicab services in Baltimore, Boulder, Denver, Pittsburgh and Kansas City, operating approximately 2,400 taxis and providing some 20 million passenger trips per year via taxi.
