The California Transit Insurance Pool (CalTIP) is a joint powers insurance authority organized under California law in 1987 in response to the lack of liability insurance coverages from the commercial insurance market. CalTIP combines the resources of public transit operators to minimize risk, increase buying power, and provide stable, affordable insurance to its members.

CalTIP is a self-insurance program for public transit operators. Rather than pay premiums to a commercial insurance company, CalTIP members pool funds to obtain affordable insurance coverage, claims administration, and safety and loss control programs. CalTIP is governed by representatives of member transit operators which ensures that the programs remain competitive with commercial offerings and continue to evolve to meet the changing needs of public transit operators.

CalTIP's excess insurance broker, Alliant Insurance Services, Inc., maintains a web site (Oasys-Net) where members can make changes to their vehicle schedules and request certificates of insurance. To access the site, just click on the banner near the top of this page. Before visiting Oasys-Net, members may wish to review Oasys-Net's instruction manual which is available on the Information page.

CalTIP serves nearly 40 transit operators.
