7.4 Work Zones, Flaggers & Road Workers
Key Takeaways
When approaching a work zone, the first thing you must do is slow down and look for guidance on how to travel through it safely.
Always obey a police officer or civil flagger in a work zone, even when the directions overrule signs, signals or pavement markings.
Speeding fines are doubled in a posted work zone.
Drums, cones and tubular markers lined up at an angle shift traffic out of a closed lane, so merge carefully into the next lane.
Orange warning signs and work equipment usually mean people are working on foot nearby; nationally, 898 people died in work-zone crashes in 2023.
Any Massachusetts road may be under construction or maintenance at any time. Work zones are marked with warning signs and traffic control devices that guide you past the hazards and protect the workers. In 2023, 898 people were killed nationally in crashes in work zones.
The First Rule: Slow Down
When you approach a work zone, the first thing you must do is slow down and look for guidance on how to travel through the area safely. Then:
- Be aware of traffic around you and of obstructions or hazards on or near the road.
- Do not be distracted by the work itself.
- Expect sudden changes in road direction or surface, and be prepared to stop.
Police Officers and Flaggers
If a police officer or civil flagger is directing traffic, follow their directions. You must always obey a traffic officer, even when the directions overrule signs, signals or pavement markings.
Civil flaggers are usually used on low-speed, low-volume roads to move traffic around the work area. A Flagger Ahead sign warns you before you reach them.
Reading Work Zone Signs
- The start of a work zone is marked with a warning sign or an electronic message sign, usually saying how far ahead the work begins.
- Advance signs tell you which lane is closed and how to move through the area. Examples include "right lane closed, move left" and "lanes shift to the right".
- Read every message and follow it.
Channelizing Devices
| Device | Purpose |
|---|---|
| Drums | Direct traffic away from a closed shoulder or lane |
| Cones | Direct traffic away from the work area |
| Tubular markers | Direct traffic away from the work area |
| Barricades | Block access to a closed lane |
Drums, cones and tubular markers are usually lined up at an angle to shift traffic from the start of a lane to the left or right. When you see them, merge carefully into the adjacent lane.
Detours and Arrow Boards
- When work closes a direction or a whole road, detour signs guide you around it and back to your route. One style marks the start of the detour and another appears along it.
- On multi-lane roads, portable arrow boards sit in the closed lane before the work area. They show which lane is closed and which way to merge: right lane closed means merge left, and middle lane closed means merge right or left.
Fines in Work Zones
If you are cited for speeding in a posted work zone (the manual also says "work area"), the fine is doubled. Massachusetts law applies the doubling whether you exceeded the posted limit or simply drove faster than was reasonable and proper in the construction zone.
Road Workers and Repair Crews
Even in a well-signed work site, take extra care for everyone working on the roadway:
- Orange warning signs and work equipment usually mean people are on foot nearby.
- Follow road work signs carefully and stay alert.
- Watch for sudden changes in road direction or condition.
- Be prepared to stop.
Roadside workers are also vulnerable road users under Massachusetts law, so you must give them at least 4 feet when passing (Section 10.1). Stopped highway maintenance vehicles with flashing lights are covered by the move-over law (Section 11.1).
Plan Ahead With 511
Dial 511 from a cell phone, or use the regional landline numbers, for 24/7 information on traffic, weather and construction. You can also report road problems.
Work Zone Scenarios
- A flagger signals you to stop while your traffic light is green: obey the flagger.
- Cones angle across the left lane ahead: that lane is closing, so signal and merge right when it is safe.
- An arrow board in the middle lane points both ways: the middle lane is closed, so merge right or left.
- Speeding at 65 in a posted 45 work zone: a 20-mph-over fine ($205 in an ordinary zone, Section 5.1), doubled, plus the risk to workers and to your record.
Why Work Zones Are So Dangerous
Work zones combine several hazards at once: lanes that shift or narrow, uneven or temporary pavement, slow or stopped traffic, equipment entering and leaving the road, and people working on foot just a few feet from moving vehicles. Many work-zone crashes are rear-end collisions caused by drivers who did not slow down early enough. Leaving extra following distance, reading the advance signs and putting the phone away let you react when traffic ahead suddenly stops.
Exam Focus
| Prompt | Correct idea |
|---|---|
| First action at a work zone | Slow down |
| Flagger versus traffic signal | Obey the flagger |
| Fines | Speeding fines doubled |
| Angled cones or drums | Merge into the open lane |
| Orange signs and equipment | Expect workers on foot nearby |
What is the first thing you must do when you approach a work zone?
Slow down and look for guidance through the area
Turn on your hazard lights and continue at the same speed
Change to the left lane immediately, whatever the signs say
Speed up so you spend as little time as possible in the zone
In a work zone, a civil flagger signals you to stop, but the traffic light ahead is green. What should you do?
Pull onto the shoulder and wait
Follow the green light
Obey the flagger and stop
Sound your horn and proceed slowly
What happens to a speeding fine issued in a posted work zone?
It is doubled
It gets a flat $50 increase
It is waived if no workers were present
It is reduced to a warning on a first offense
