Toyota HiAce
The base vehicle is usually a retired North American school bus on a light or medium truck chassis. The word "chicken" may refer to the fact that the buses are often crammed with passengers not unlike a truck load of chickens, or to the fact that Central Americans occasionally transport live animals on such buses–a practice that visitors from other countries often find remarkable. In Panama, the base vehicle can also be a passenger Toyota HiAce or Toyota Coaster or similar and is often left painted white. If a Toyota Coaster is used, the bus is known locally as a "Chiva", and if a Toyota HiAce is used, the van is called a "busito" instead.
