Until now, prisoner transportation buses and security vehicles were built for other purposes then retrofitted to transport passengers. At Krystal, we build our security transports from the ground up, with your purpose and budget in mind. As a high quality security vehicle and prisoner transport manufacturer, safety and security of all passengers is our primary mission. In addition to our Prisoner Transport, we also have 6 and 8 door personnel hummer transports, as well as specially designed Personnel Transport Coach SWAT vehicles with capacities from 10 to 40 passengers.
