Two horses were loaded onto a public transport bus in Detroit / Authorities are investigating the case

Authorities in Detroit are investigating an unusual incident in which two saddled horses were led onto a public transit bus. The incident occurred on Saturday, and footage captured by a witness went viral online.

The recording shows two people loading the animals onto the bus while the vehicle was stopped at a bus stop. After a few seconds, the horses and their handlers exited through the rear doors. It is not known how many passengers were on the bus at the time or whether anyone was injured.

The Detroit Department of Transportation (DDOT) confirmed Tuesday that it is reviewing the circumstances of the incident. Representatives of the institution said that bringing horses onto the bus violates public transit policy and could have created a dangerous and uncomfortable situation for passengers.

DDOT regulations allow only assistance animals to access public transportation. They must remain under the control of the person with a disability whom they accompany at all times, must not occupy a seat, and must stay on the floor or in the handler’s lap. Authorities have not yet announced the identities of the people involved or any possible penalties.
