Often, the causal factors for most workzone accidents are improper signage, striping, and markings deployed by the in the field.

Another factor to consider while investigating workzone accidents is the fact that design and deployment of the traffic control may not comply with the succinct and established standards for workzone signing, striping, and marking as required and mandated by the federal and local governments.

The Professional Traffic Operations Engineers at Accident Diagnostics are trained specifically in work-zone traffic control and in the Manual for Uniform Traffic Control Devices (MUTCD). They can evaluate the existing conditions and determine the existence of violations in the deployed traffic control at the work zone during the time of the accident.
