Commercial umbrella

How does a commercial umbrella sit over auto liability, general liability, and employer's liability?

An umbrella is a layer, not a standalone policy. The base layer is your underlying liability coverage. The umbrella is written to sit above it.

• Auto liability. The limit on your primary auto liability is the first dollar that pays for an accident your truck causes. If the claim is larger, the umbrella may pay on top of that limit for covered losses.
• General liability. Same idea over the limit on your general liability for premises and operations claims.
• Employer's liability. This is the part of a workers' compensation policy that covers certain suits against you by injured employees. Some umbrellas sit over it too. See workers' compensation.

The umbrella generally does not start paying until the underlying limit is used up by a covered claim, and it usually requires you to keep those underlying policies in force at stated minimum limits. If the underlying policy lapses or is cancelled, the umbrella may leave a gap or exclude the claim. Read the "schedule of underlying insurance" in the umbrella.

Umbrella versus excess. Insurers and contracts use "umbrella" and "excess" in different ways. An umbrella may be broader than the underlying policy in places. An excess policy may simply follow the underlying wording with no additional coverage. Do not assume. Ask which one you are looking at and read how it follows the underlying form.

Trucking auto liability is a special case. Whether an insurer will write umbrella or excess limits over trucking auto liability, and what it requires underneath, varies by insurer, fleet, and operation. Ask what an umbrella would need under it before you count on one.

Why contracts ask for it. Contracts commonly set liability limits higher than a base policy carries, to put more money behind a serious claim. A broker-carrier agreement, a shipper's carrier requirements, a lease, or a lender's covenant may list a total liability limit that is met by underlying plus umbrella together. Read the clause for what counts toward the number, and for who must be named on the certificate. Whether a contract requires an umbrella is a question for the contract, not for us.

What does a commercial umbrella cover, and what doesn't it?

Policies vary. Read your declarations, definitions, and exclusions. In general:

Often covered

• Covered bodily injury and property damage claims that exceed the limit of a listed underlying policy, up to the umbrella's limit
• Defense costs for covered claims, either inside or in addition to the limit, depending on the policy
• Some claims the underlying policy excludes, under a broad umbrella, subject to a retention. This varies and is not universal.

Often not covered, or covered only with conditions

• Anything not on the schedule of underlying policies. A coverage line, unit, or location that is not scheduled may fall outside the umbrella.
• Claims below the underlying limit. The underlying policy handles those.
• Damage to your own property, cargo, and equipment. That is physical damage, motor truck cargo, and similar first-party coverage. An umbrella is liability coverage.
• Professional errors and omissions, employment claims, and cyber losses, commonly excluded. See professional liability, management liability, and cyber.
• Pollution and hazardous materials losses, commonly excluded or limited, depending on the policy
• Contractual liability, intentional acts, and punitive damages, where excluded by the policy or by law
• Employer's liability and workers' compensation benefits, commonly limited: the umbrella may sit over employer's liability but does not pay comp benefits

These are common patterns, not universal ones. The umbrella's exclusions can differ from the underlying policy's, so read it as its own document.

What affects the cost of a commercial umbrella?

We don't publish prices. Cost is set by insurers and the licensed agents you work with. These are the factors that generally move it:

• Limit you ask for. The amount above the underlying policies
• The underlying policies. Their limits, their carriers, and their own cost
• Fleet size and radius. Number of power units and how far and where they run
• What you haul. Commodity and any hazardous materials
• Drivers and safety record
• Loss history on the underlying lines
• Operations beyond the road. Premises, shop work, or towing
• Contract requirements. What limits and wording a broker, shipper, or landlord asks for
• Retentions. What the umbrella leaves to you if an underlying policy does not respond

Who typically needs a commercial umbrella?

• Small fleets: More trucks and drivers mean more exposure to a single large accident. Contracts often key to total limits.
• OTR and local haul: Interstate and long-haul operations face large-loss exposure on the road. Read your customers' carrier requirements before you shop.
• New authority: Some brokers and shippers set total limits that a first policy alone does not meet. Ask what is available for a carrier with little history. No one can promise what an insurer will offer.
• Brokers and dispatchers: If you have a premises exposure, an umbrella over general liability may come up. Contingent auto liability has its own policy limits: see contingent auto liability.
• Towing and repair: Wreckers, shop operations, and customer vehicles carry large-claim potential. A lender or a customer contract may ask for higher limits than the base policies carry.
• Couriers: Contract customers occasionally ask for umbrella limits. Read the contract.
