A crash boot attaches to the front of the locomotive. When inflated, the boot provides a shock absorber for absorbing the impact energy produced when the locomotive collides with another object. By absorbing this energy, the boot protects both the locomotive and its crew, and the other object such as a vehicle and its occupants from severe injury or harm. In a highway environment, a trailer is towed behind a vehicle to a work site. The trailer is parked with one end facing on-coming traffic. This end of the trailer has an inflatable boot which is inflated while the crew is at work. If an on-coming vehicle now collides with the boot, it absorbs the impact of the collision and lessens the damage resulting therefrom.
