Attenuator Truck Insurance
Attenuator trucks, TMA trucks, crash cushion trucks, and shadow vehicles are not ordinary commercial trucks. They are used in work zones where traffic, construction crews, lane closures, contract requirements, and expensive vehicle-mounted safety equipment all collide.
Kelly Insurance Group helps highway contractors, traffic control contractors, roadway safety companies, and specialty fleet operators explain the actual operation before the account is sent to underwriting.
Commercial Auto / TMA Vehicle Use
Underwriters will want to understand the vehicle schedule, radius, states of operation, drivers, contracts, garaging, work zone use, and whether the unit is owned, leased, rented, or subcontracted.
Why this coverage deserves attention
A TMA truck is a work zone safety vehicle, not just a truck.
A truck mounted attenuator may be used as a shadow vehicle, lane closure vehicle, traffic control support unit, or roadway safety vehicle. That use changes the insurance conversation.
The insurance review should separate the truck, the attenuator equipment, the work zone operation, the driver exposure, the crew exposure, the contract requirements, and the certificate wording.
A clean submission should explain where the trucks operate, what type of road work is supported, whether the contractor performs traffic control, whether the unit is rented to others, and whether the company is working for municipalities, utilities, general contractors, highway contractors, or public agencies.
Coverage structure
The program should match the work zone operation.
Commercial Auto Liability
Should be reviewed around the vehicle schedule, use, radius, drivers, contracts, and roadway work zone exposure.
Physical Damage
Truck values, attached equipment, crash cushion units, arrow boards, and specialized modifications should be described clearly.
General Liability
May be relevant for traffic control operations, non-auto premises or operations exposures, subcontractors, and contract requirements.
Umbrella / Excess Liability
Highway contracts, municipal work, utility projects, and public agency work may require higher liability limits.
Workers Compensation
Should be reviewed based on drivers, flaggers, traffic control crews, setup crews, and applicable state requirements.
Inland Marine
May be needed for portable message boards, cones, arrow boards, signs, tools, temporary traffic control equipment, and other mobile property.
Hired & Non-Owned Auto
Important when vehicles are rented, borrowed, subcontracted, or employees use vehicles connected to the operation.
Certificates of Insurance
Owners, GCs, municipalities, utilities, and project managers may request additional insured and other certificate wording.
Loss History
Prior losses, windshield claims, rear-end impacts, vehicle damage, and work zone incidents should be disclosed accurately.
Do not describe this as a normal trucking account.
Attenuator truck operations should be submitted with the work zone context. The underwriter needs to know how the truck is used, where it operates, what equipment is attached, and what contract requirements apply.
Start the ReviewOperations we want disclosed
Different roadway operations create different insurance questions.
Truck mounted attenuator units in live traffic
Review vehicle schedule, equipment values, drivers, road type, states of operation, contracts, and whether the unit is used by your employees or rented to others.
Lane closures, cones, signs, boards, and work zone setup
Traffic control operations may create general liability, auto, workers compensation, inland marine, and certificate requirements.
Roadway construction and contractor support
Contractors should disclose whether TMA units are part of paving, striping, utility work, bridge work, emergency repair, or construction support.
Government, utility, and public agency contracts
Public work may involve specific insurance requirements, additional insured language, waiver requests, higher limits, and certificate deadlines.
Owned units, rented units, and subcontracted equipment
Disclose who owns the truck, who operates it, who maintains it, who insures it, and what the rental or subcontract agreement requires.
