1. Micro (blue bus) - about half or so of the regular bus size, similar to yellow school buses in the US. Cheapest and slowest option.
2. Mini (white minivan) - capacity is about 14 passengers, the most frequent of all public transportation options, have fixed routes that are listed on the front windshield (and yelled out the window by the driver's sidekick every 5 seconds). Sidekick (usually a teenage kid) also collects fares from the passengers. The cost is from 1 to 2.3 Bolivianos, depending on the distance and the time of day.
3. Trufi (car on the right) - "Taxi de Ruta Fija", taxis that have set routes (also listed on the front windshield; no sidekick). Capacity is 5 passengers, as they somehow fit 2 people next to the driver (and the car is with a stick shift). The cost is 3 Bs.
4. Taxi (behind the micro) - the same as anywhere else. The cost is usually 12 or 15 Bs for most distances.
Note: 1 USD = 7 Bolivianos
