Commercial Truck Insurance Explained: How Policy Limits Affect Your Settlement

Commercial truck insurance is structured differently from passenger auto insurance — higher limits, multiple coverage layers, specific federal requirements. Understanding the structure helps victims and counsel identify all available insurance and maximize recovery.

Federal Minimum Insurance Requirements

The Federal Motor Carrier Safety Administration (FMCSA) sets minimum liability insurance requirements based on cargo:

General Freight: $750,000

Interstate commercial trucks carrying general freight must carry minimum $750K liability insurance.

Hazardous Materials: $1M-$5M

• Class 8 hazardous (corrosive): $1M
• Most hazmat in tank vehicles >3,500 gallons: $5M
• Other hazardous materials: $1M-$5M depending on specifics

Household Goods: $300,000

Federal minimum for movers carrying household goods.

Property in Interstate Commerce: $750,000

General federal minimum.

State Minimums (Intrastate)

State minimums for intrastate trucking typically lower:

• $25K-$300K depending on state and vehicle class
• Light commercial trucks may have lower requirements
• Specific state regulations

Common Actual Coverage

Most commercial carriers carry well above federal minimums:

Single-Truck Owner-Operators

Often carry $1M-$2M policies (slightly above federal minimum).

Mid-Size Carriers

Typically carry $1M-$5M primary coverage plus umbrella excess.

Major National Carriers

Often carry $10M+ in combined coverage including:

• Primary liability ($1M-$5M)
• Excess liability ($5M-$25M)
• Umbrella ($25M-$100M+)

High-Risk Cargo

Trucks carrying hazardous materials or expensive cargo often carry substantially more.

Insurance Structure Layers

Primary Insurance

First layer of coverage. Pays claims up to policy limit.

Excess Insurance

Activates when primary is exhausted. Higher limits, lower premiums per dollar of coverage.

Umbrella Insurance

Broad coverage above all other policies. Sometimes covers gaps.

Self-Insured Retention

Some carriers self-insure smaller amounts, then carry excess insurance.

Captive Insurance

Large carriers may have captive insurance companies (subsidiaries that insure parent company).

MCS-90 Endorsement

Federal trucking insurance includes the MCS-90 endorsement — a guarantee that insurance will pay even if policy exclusions would normally apply.

Key features:

• Pays even if driver violated policy terms (intoxication, unauthorized use)
• Pays even if cargo not covered by policy
• Pays even if carrier failed to disclose risks
• Insurance company can seek reimbursement from insured

For accident victims, MCS-90 means insurance pays regardless of carrier’s actions — substantial protection.

Other Available Coverage

Cargo Insurance

Covers cargo damage. Separate from liability.

Bobtail Insurance

Covers tractor when not pulling trailer.

Non-Trucking Liability

Covers personal use of tractor.

Workers’ Compensation

For drivers injured on job.

Insurance Available for Different Parties

In a truck accident, potentially available insurance:

Driver’s Personal Insurance

Personal auto policy. May supplement commercial policy.

Motor Carrier’s Insurance

Primary commercial policy + excess + umbrella.

Truck Owner’s Insurance

If different from carrier.

Trailer Owner’s Insurance

Sometimes separate from tractor.

Cargo Loader’s Insurance

If loading contributed.

Maintenance Company’s Insurance

If maintenance failure contributed.

Manufacturer’s Insurance

If defective component caused crash.

Broker’s Insurance

Some freight brokers carry liability insurance.

Your Own UM/UIM

Your auto policy’s uninsured/underinsured coverage.

Policy Stacking

When multiple insurance policies potentially apply, “stacking” combines them:

Vertical Stacking

• Primary policy pays first
• Excess pays next
• Umbrella pays last

Horizontal Stacking

• Multiple potentially liable parties’ policies
• Each pays separately or proportionally

Anti-Stacking Provisions

Some policies attempt to prevent stacking. State law often overrides such provisions for victims’ benefit.

When Insurance Is Exhausted

In catastrophic cases, available insurance may not cover all damages:

Identify Additional Defendants

Pursue all potentially liable parties for additional insurance pools.

Underinsured Motorist Coverage

Your own UIM applies if defendant’s insurance is insufficient.

Personal Assets

Defendants’ personal assets become accessible (though bankruptcy may eliminate this).

Structured Settlement

Insurance may pay limits over time rather than lump sum.

Settlement Implications

Within Policy Limits

Insurance company typically settles for available limits when:

• Liability is clear
• Damages exceed policy limits
• Plaintiff is willing to release insured beyond policy

Bad Faith Insurance Practices

Insurance companies have legal duties to:

• Investigate claims promptly
• Settle within policy limits when reasonable
• Communicate offers in good faith

Failure to do these can result in “bad faith” liability — insurance company may be liable beyond policy limits for damages caused by their bad faith conduct. Substantial additional recovery possible in bad faith cases.

Excess Carrier Strategies

Excess carriers monitor primary case and:

• May contribute to settlement when primary limits approach
• May require trial to expose excess liability
• Often delegate authority to primary or take over case

Discovery of Insurance

In most states, insurance information must be disclosed in discovery. However, this happens after suit is filed. Pre-litigation, insurance details may not be disclosed.

Your attorney can:

• Subpoena insurance information
• Use court-ordered insurance disclosure
• Request all available insurance through discovery process

Common Defense Insurance Tactics

Reservation of Rights Letters

Insurance company defends but reserves right to deny coverage. This can affect settlement leverage.

Coverage Disputes

Disputes about whether specific policy applies (was driver acting within scope of employment? was vehicle covered?). Can complicate cases.

Policy Limit Concerns

Insurance company protecting policy limits from over-policy settlement. Negotiating tactic.

Multiple Defendant Allocation

When multiple insurers involved, allocation disputes can delay settlement.

Frequently Asked Questions

How do I find out the trucking company’s insurance limits?

Through legal discovery. Most states require disclosure. Pre-litigation, insurance company may not disclose voluntarily.

Can I get more than the insurance policy limit?

Possible through:

• Multiple defendants (each with own insurance)
• Bad faith claims against insurance company
• Personal assets of defendant (limited practical recovery)
• Your own UIM coverage

What’s the MCS-90 endorsement?

A federal requirement guaranteeing insurance payment even when policy exclusions might apply. Protects victims of catastrophic crashes.

How much insurance does a typical truck carry?

Federal minimum: $750K. Most carriers exceed this. National carriers often carry $5M-$100M+ in combined coverage.

What if multiple plaintiffs share one policy?

Policy limits divided among plaintiffs based on injury severity and other factors. Court may oversee distribution in complex cases.
