MCS-90: Endorsement, Form, Filing & More

What is The History Of The MCS90 And Why Was It Enforced?

To understand MCS90, we must first take a look at how it came to be and why it was enforced in the first place. 

The United States once heavily regulated trucking businesses in 1887 through the Interstate Commerce Act, which controlled the cost of transporting products and aimed to ensure fair rates. 

Following the years after President Grover Cleveland signed it, the Interstate Commerce Act of 1887 underwent a series of amendments, so that it could keep up with the emerging trends in the trucking, railroad, and airline industries. 

The Motor Carrier Act, which President Jimmy Carter signed into law in 1980, is the 9th of such amendments that preceded the abolition of the Interstate Commerce Act. 

Provisions of the Motor Carrier Act of 1980 targeted motor carriers. Aside from ensuring fair competition and making it easier to do business, it has another prominent feature. It required interstate and for-hire motor carriers to carry the FMCSA minimum insurance to take care of damage and casualties arising from the accidents caused by their vehicles

The amount of liability coverage required is hefty. And the commercial auto insurance of most motor carriers can’t meet this. To solve this problem, the motor carriers do an MCS 90 filing to comply with the Motor Carrier Act of 1980 minimum insurance requirements.

Common Terms Used In The Language of MCS 90

  • MCS 90 provides a minimum $750,000 liability coverage for motor carriers that transport non-hazardous properties in interstate or foreign commerce

  • Motor carriers in the public transportation sector using vehicles with a 14-person capacity can get a minimum $1 million coverage from MCS 90

How Does MCS90 Work?

To understand how MCS 90 works, let’s take a look at a series of paragraphs written in the “Definitions” section of the MC 90 form. 

Paragraph 1

“The insurance policy to which this endorsement is attached provides automobile liability insurance and is amended to assure compliance by the insured, within the limits stated herein, as a motor carrier of property, with Sections 29 and 30 of the Motor Carrier Act of 1980 and the rules and regulations of the Federal Motor Carrier Safety Administration (FMCSA)”

The first paragraph in the “Definitions” section tells us that MCS 90 grants an additional layer of coverage and ensures that the commercial auto insurance to which it is endorsed complies with the minimum MCS 90 requirements imposed by the FMCSA and the Motor Carrier Act of 1980. 

Paragraph 2 (Clauses 1, 2, 3, And 4)

“In consideration of the premium stated in the policy to which this endorsement is attached, the insurer (the company) agrees to pay, within the limits of liability described herein, any final judgment recovered against the insured for public liability resulting from negligence in the operation, maintenance or use of motor vehicles subject to the financial responsibility requirements of Sections 29 and 30 of the Motor Carrier Act of 1980 regardless of whether or not each motor vehicle is specifically described in the policy and whether or not such negligence occurs on any route or in any territory authorized to be served by the insured or elsewhere”

The first clause of MCS90’s second paragraph gives an idea about the scope of the coverage. As stated, the insurance company, through the MCS90 endorsement, can cover costs when there’s a judgment that requires you to compensate third party bodily injuries, property damage, or environmental restoration. Also, MCS90 provides protection when liability results from negligence which occurred in any route or territory when you’re trucking. 

“Such insurance as is afforded, for public liability, does not apply to injury to or death of the insured’s employees while engaged in the course of their employment, or property transported by the insured, designated as cargo.”

The third clause states that MCS90 endorsement doesn’t extend its protection to the injury or death of your commercial vehicle’s driver and passengers. Also, you can’t use it to cover losses if your business property got damaged or lost during the trip.

“However, all terms, conditions, and limitations in the policy to which the endorsement is attached shall remain in full force and effect as binding between the insured and the company”

This third clause states that the terms and conditions of the insurance policy also apply to the MCS90 endorsement. And that any violations of the MCS90’s public liability coverage between both parties can be a ground for gaining compensation or filing a lawsuit. 

“The insured agrees to reimburse the company for any payment made by the company on account of any accident, claim, or suit involving a breach of the terms of the policy, and for any payment that the company would not have been obligated to make under the provisions of the policy except for the agreement contained in this endorsement.”

The fourth clause of the MCS90’s second paragraph states that the insurance company can demand reimbursement from you if it provided indemnification when it shouldn’t have otherwise. Here are some situations where this can happen:

  • The MCS90 provided coverage for an accident caused by a commercial vehicle you didn’t name on its terms

  • Insurance fraud 

Paragraph 3

“It is further understood and agreed that, upon failure of the company to pay any final judgment recovered against the insured as provided herein, the judgment creditor may maintain an action in any court of competent jurisdiction against the company to compel such payment.”

The third paragraph paves the way for legal recourse in case you can’t get covered without justifiable reason. If there’s MCS 90 and the insurance company denies coverage even though the peril is 100% covered, you have all the right to contest in a court of law and demand the insurance company to do its job. 

Paragraph 4

“The limits of the company’s liability for the amounts prescribed in this endorsement apply separately to each accident and any payment under the policy because of any one accident shall not operate to reduce the liability of the company for the payment of final judgments resulting from any other accident.”

The fourth paragraph of the “Definitions” section tells us that the public liability coverage of MCS90 applies on a per accident basis. 

In Practice, When Does MCS90 Provide Coverage?

You must remember that the coverage of MCS 90 doesn’t override the coverage of your commercial auto insurance. In this section, we’ll discuss the conditions that trigger MCS 90. 

The first condition is that your commercial vehicle must have caused an accident while engaged in interstate, intrastate, or foreign commerce while carrying a specific property specified in the provisions of the Motor Carrier Act of 1980. 

Moreover, the court must have released a final judgment of negligence regarding the accident to which you’re liable. Also, the lawsuit must have been filed by a third party who is a victim. This is the second condition. 

The third condition is that your commercial auto insurance must fail to cover the judgments, and you have no other means of taking care of the costs. 

If all of these conditions are met, then you can ask the insurance company to grant coverage through MCS 90.

Again, remember that you can dispute in a court of law if the insurance company refuses to help you out. 

How To File Your MCS90 Endorsement?

First off, know that you don’t do the MC 90 filing at FMCSA’s office or website. Instead, the documents you need to submit to the agency are the BMC-91 or BMC-91X, which proves the endorsement has been introduced to your commercial auto insurance. 

So who will help you file the MCS90 endorsement? The one who will do the work will be the insurance company. All you have to do is provide a filled-up copy of the MCS 90 form 2020-2024.

MCS-82 filing is what’s commonly known as motor carrier public liability surety bond. This agreement ensures that the principal has the minimum insurance requirements imposed by the FMCSA. 

As for self-insurance, this is the act of setting aside specific amounts of money for the purposes of paying the responsibilities to the public in case your commercial vehicle causes an accident.
