A work zone is an area of a highway with construction, maintenance, or utility work activities. A work zone
is typically marked by temporary traffic control (TTC) devices consisting of signs, channelizing devices,
barriers, pavement markings, and/or work vehicles. A work Zone extends from the first warning sign or high-intensity
rotating, flashing, oscillating, or strobe lights on a vehicle to the END ROAD WORK sign or the last TTC device.
Every year, more than 1,000 fatalities occur in our nation's workzones.
More than 40,000 people are injured each year as a result of motor vehicle crashes in work zones.
