Big Blue Bus currently maintains a fleet of 195 buses of various lengths including 29', 40', and 60' articulated, with 35-footers set to be delivered in 2025. All buses feature
destination signs. Newer buses (units 1801 and later) feature white LED destination signs, while older units feature a variety of other colors. In 2024, the fleet was equipped with passenger information displays in place of the older dot-light signs. These are part of a fleet-wide communications system replacement with Clever Devices systems. The passenger displays currently feature a three-day weather forecast, upcoming stops with time to arrival, and the line's final destination. As part of this upgrade, electric buses also gain access to Clever's EV fleet integration software during the agency's transition to a zero-emissions fleet. This also enables The agency has determined that battery-electric buses can replace their CNG buses at current service levels with a 1:1 replacement ratio. Moreover, Big Blue Bus' 2011 NABI LFW 40' and NABI BRT 60' units have already exceeded their design life. The agency has subsequently delayed its fleet electrification deadline to 2031.
Active fleet Awaiting Delivery Retired Future and electrification Following the success of Big Blue Bus' pilot with a prototype Gillig/Cummins BEB (unit 1827), the agency committed to only purchasing zero-emission vehicles moving forward. Big Blue Bus charges its electric fleet with 100 percent
renewable energy. The second batch of battery-electric buses are expected in 2025. The agency has set itself a 2030 deadline for full conversion to zero-emissions operation, which as of February 2023, it has determined it can achieve with exclusively
battery-electric buses. The agency is slated to replace vehicles as they reach the end of their useful service lives. Next to be replaced are El Dorado 32' BRT models, with delivery of replacement Gillig 35' Low Floor EVs slated for 2025. The agency's fleet of remaining NABI vehicles is the next group of buses to be replaced. Due to dynamic service changes, the impact of the COVID-19 pandemic, and ridership changes, amongst other factors, the agency is pursuing a more dynamic fleet replacement timeline than that which was outlined in their original
CARB document. The agency has delayed its fleet electrification commitment to 2031. == Incidents ==
