Bihar, one of India's most populous states with over 12 crore people, uses the vehicle registration prefix BR. The Bihar Transport Department manages RTO offices across 38 districts, with the state capital Patna (BR-01) housing the largest and most active RTO. Bihar's vehicle market has been growing rapidly as the state's economy has developed, remittances from Bihari migrants across India and the Gulf flow back, and road infrastructure improves under the state government's focus on connectivity.
Bihar presents a unique transport picture - it has one of India's highest rates of two-wheeler ownership relative to car ownership, reflecting the state's income profile and road conditions. The Sone, Gandak, Kosi, and Bagmati rivers create natural barriers that historically impeded road development, but the construction of new bridges and NH projects under the Nitish Kumar government has significantly improved connectivity.
Bihar is also a major source state for seasonal migrant workers - the "Bihari migrant" is one of India's most mobile labour groups, moving to Delhi, Mumbai, Surat, and other industrial cities for work and returning seasonally. This creates unique transport demand during festivals like Chhath Puja and Makar Sankranti, when Bihar's RTOs see surges in NOC requests and inter-state vehicle movements.
