How many doorways must a vehicle have when transporting six or more horses?

When transporting six or more horses, safety and accessibility become critical factors. The requirement for a vehicle to have two doorways ensures that there is adequate access for both loading and unloading the horses. This design allows for effective management of both horse and human traffic, critical in situations where quick entry or exit may be needed.

Having two doorways provides flexibility and minimizes the risk of overcrowding or accidents during the transport process. It also enhances safety by allowing handlers to access the horses from different sides of the vehicle, facilitating better care for the animals and improving the overall handling process in accordance with best practices in equine transportation.

In contrast, a vehicle with only one doorway would significantly increase the risk of dangerous situations, as all movements would need to occur through a single point of access, potentially causing stress to the horses and handlers. It's essential to prioritize the safety and efficiency of transport practices, which is why having two doorways is mandated in this context.
