A crash that occurs in or related to a construction, maintenance, or utility work zone, whether or not workers were actually present at the time of the crash. "Work zone-related" crashes may also include those involving motor vehicles slowed or stopped because of the work zone, even if the first harmful event occurred before the first warning sign.
The use of these fields does not imply that the crash was caused by the construction, maintenance, or utility activity.
Indicate if the crash was in or near a construction, maintenance, or utility work zone.
Work Zone:
A work zone is defined as an area of a trafficway where construction, maintenance, or utility work activities are identified by warning signs/signals/indicators, including those on transport devices (e.g., signs, flashing lights, channelizing devices, barriers, pavement markings, flagmen, warning signs and arrow boards mounted on the vehicles in a mobile maintenance activity) that mark the beginning and end of a construction, maintenance, or utility work activity.
A work zone extends from the first warning sign, signal or flashing lights to the END ROAD WORK sign or the last traffic control device pertinent to that work activity. Work zones also include roadway sections where there is ongoing, moving (mobile) work activity such as lane line painting or roadside mowing only if the beginning of the ongoing, moving (mobile) work activity is designated by warning signs or signals.
Work Zone Crash:
A Work Zone Crash is a motor vehicle traffic crash in which the first harmful event occurs within the boundaries of a work zone or on an approach to or exit from a work zone.
To determine which option is appropriate, the duration of the work must be considered. If the work is short-term (i.e., takes less than one period of daylight and is not performed during hours of darkness), 02 - Maintenance or 03 - Utility are applicable. If the maintenance or utility work is long-term, 01 - Construction must be used.
00 - None is used when it is reasonably certain that the crash is not considered a work zone crash as defined above.
If this option is selected make sure that the LOCATION OF THE CRASH, TYPE OF WORK ZONE, WORKERS PRESENT and LAW ENFORCEMENT PRESENT fields are set to 97 - Not Applicable.
01 - Construction is used when there is long-term stationary construction such as building a new bridge, adding travel lanes to the roadway, extending an existing trafficway, etc. Highway construction includes construction of bits and pieces such as guardrails or ditches, surveying activity, installation of utilities within the right-of-way, etc.
02 - Maintenance is used when there are work activities, including moving work activities, such as striping the roadway, median and roadside grass mowing/landscaping, pothole repair, snowplowing, etc., where there are warning signs or signals marking the beginning of the moving work area.
03 - Utility is used when there is short-term stationary work such as repairing/maintaining electric, gas, water lines or traffic signals. The utility company must perform the work.
04 - Work Zone, Type Unknown is used when there is insufficient information to distinguish between 01 - Construction, 02 - Maintenance or 03 - Utility.
