LATCHES/LOCKS/LINKAGES:DOORS:LATCH
Certain work trucks are not equipped with either a primary door latch system or a door latch system with a fully latched position and a door closure warning system as required by FMVSS 206. Without a door closure warning system, the driver may not be aware that the door is not fully latched. The door could partially open without warning and the driver may be at an increased risk of injuries in the event of a crash.
