If you’ve been injured in a truck accident, you may hear the term MCS-90 endorsement. Although it sounds technical, this federal insurance endorsement can play an important role when questions arise about a trucking company’s insurance coverage after a crash.
While an MCS-90 endorsement does not guarantee compensation, it may help protect people injured by certain commercial motor vehicles. Understanding how it works can help you protect your legal rights after a truck accident.
What Is an MCS-90 Endorsement?
An MCS-90 endorsement is a federally required provision added to certain commercial motor vehicle liability insurance policies. It helps ensure that interstate motor carriers can be held financially responsible for injuries or property damage they cause, even if the insurance policy might not otherwise cover the accident.
An MCS-90 endorsement is not a separate insurance policy. Instead, it is attached to a qualifying commercial auto policy and may require the insurer to pay certain judgments against the motor carrier.
When Does the MCS-90 Matter?
Many truck accident claims are resolved without ever raising issues involving an MCS-90 endorsement. However, the endorsement may become important when the trucking company’s insurance carrier argues that the accident falls outside the policy’s normal coverage.
For example, coverage disputes sometimes arise because:
- The truck involved was not specifically listed on the insurance policy
- The driver was operating a different vehicle than expected
- The policy contains exclusions that the insurer believes apply
- The trucking company violated certain policy conditions
- Questions exist about the ownership or use of the commercial vehicle
In some cases, an MCS-90 endorsement may require the insurer to pay certain judgments even when the insurance policy would not otherwise provide coverage.
Does Every Truck Have an MCS-90 Endorsement?
No. Not every commercial truck operating on Washington roads is required to have an MCS-90 endorsement. Generally, the endorsement applies to certain interstate motor carriers that are subject to federal financial responsibility requirements.
Whether an MCS-90 endorsement applies depends on several factors, including:
- Whether the trucking company operates in interstate commerce
- The type of cargo being transported
- The size and classification of the commercial vehicle
- Federal regulatory requirements
- The motor carrier’s operations
Some trucking companies operate solely within one state. This type of operation may be governed primarily by state insurance requirements.
Determining whether an MCS-90 endorsement applies often requires reviewing the trucking company’s operations, insurance policy, and applicable federal regulations.
How Can an MCS-90 Affect a Truck Accident Case?
The existence of an MCS-90 endorsement can make a significant difference when insurance coverage becomes disputed.
Imagine a situation where a trucking company’s insurer denies coverage because it believes a policy exclusion applies. Without an MCS-90 endorsement, recovering compensation may be more difficult if the trucking company lacks enough assets to satisfy a judgment.
With an MCS-90 endorsement, the insurer may still have an obligation to satisfy judgments for public liability. This can help provide injured victims with another potential source of compensation.
How a Truck Accident Lawyer Can Help
Truck accident cases are usually more complicated than other personal injury claims. They may involve complex federal regulations, insurance policies, and MCS-90 considerations.
A personal injury lawyer can help by:
- Conducting detailed investigations
- Preserving important evidence
- Reviewing insurance policies
- Reviewing applicable federal regulations
- Identifying potentially liable parties
- Pursuing fair compensation for economic and non-economic damages
If insurance coverage is disputed, an attorney can evaluate whether an MCS-90 endorsement affects your case.
