Abstract: A protective enclosure for a bus driver includes a back wall fabricated from steel and secured to the inner walls of a bus by means of suitable angle irons or braces. A main support column is secured to the back wall at the other end. The back wall has a central area fabricated from a relatively impenetrable transparent material. A side section extends at right angles to the back wall and includes a door for gaining access to the enclosure. The door can be operated by means of a push bar located on the inside of the enclosure to enable a driver to exit the enclosure. The door also contains relatively large glass areas to provide an unobstructed view both to the driver and the passengers. Other features which include two-way communications and emergency devices are also disclosed.
