To manage overall road transport facilities in the state, Bihar State Road Transport Corporation (BSRTC) was set up in 1959 under the provisions of Road Transport Corporation Act, 1950.
BSRTC operates and maintains a fleet of more than 300 buses connecting all cities and towns within state of Bihar and neighboring states too. BSRTC not only connects every nook and corner of the state but also links this state with other surrounding regions including Uttar Pradesh, Jharkhand, Chhattisgarh, West Bengal and Odisha. However, contract for operation and maintenance of the buses has been given to two private companies viz. GIPL and Royal Cruiser. This contract is based upon public-private partnership (PPP) <ref>"Transport Services in Bihar, Roadways in Bihar, Railways in Bihar". www.biharonline.in. Retrieved 2024-02-28.</ref>
