The same commercial auto policy add-ons from the explorer above, listed out. Form names and availability vary by carrier.
Endorsement
Adds a person or organization to liability when a contract demands it.
Job sites and landlords ask to be additional insured on commercial auto, not just general liability. The certificate of insurance is not the coverage. Blanket additional-insured endorsements are easier than naming every GC — if the carrier files one that matches the contract.
Endorsement
One liability limit instead of split bodily injury / property damage.
Contracts and certificates often specify CSL rather than split limits. An endorsement or a different declarations setup can put the auto liability on a combined single limit. We match the number to the contract, not just to a personal-auto habit.
Endorsement
Covers a business owner who has a company car but no personal auto.
Drive-other-car coverage can protect someone furnished a company vehicle who does not keep a personal auto policy, when they drive a car they do not own. Borrowing a friend’s car without DOC is a classic gap. It is not a substitute for listing household drivers on a personal auto.
Endorsement
Customers’ vehicles in your care — if you park or service them.
If you valet, service, or store customers’ autos, garagekeepers is the bailee coverage. It is often a commercial auto or garage endorsement, not CGL. Dealers and shops need a dedicated conversation; a plain business auto form may not be enough.
Endorsement
Liability — and sometimes physical damage — on vehicles you rent.
Hired auto covers autos you lease, hire, or borrow (not employee-owned). Illinois contractors and sales teams who grab a Hertz van for a job need this symbol set correctly. Physical damage on rented units is a separate yes/no from liability.
Endorsement
A federal endorsement for certain motor carriers — public liability.
MCS-90 is not optional window dressing. Qualifying interstate (and some intrastate) motor carriers must have it. It is a surety-like public liability endorsement, not extra physical damage. Filings and BMC-91X go with it. Radius and commodity change whether you need it.
Endorsement
Liability when employees use their own cars on company business.
Non-owned auto is for the business’s liability if an employee runs an errand in a personal vehicle. It does not repair the employee’s car. Pizza shops, real-estate teams, and service companies trip this one. Personal auto still needs to be in force for the driver.
Optional coverage
A substitute commercial vehicle while yours is repaired.
A downed work van is lost jobs, not just inconvenience. Rental reimbursement on commercial auto helps pay for a substitute unit after a covered comprehensive or collision loss. Limits are daily and total caps. Downtime beyond the rental is a different coverage conversation.
Optional coverage
Tow limits for a disabled scheduled auto.
Commercial towing bills on a box truck are not sedan prices. Optional towing coverage sets a per-disablement cap. It does not replace hired auto if you rent a replacement, and it does not cover cargo.
Endorsement
Physical damage for trailers you hook that you do not own.
If you pull someone else’s trailer under an interchange agreement, trailer interchange covers that trailer for collision and comprehensive-type losses while in your care. Motor carriers and some local haulers need it. It is not motor truck cargo.
Endorsement
Stops your insurer from chasing another party after a claim.
Construction and vendor contracts often require a waiver of subrogation on auto as well as GL. Without the endorsement, the carrier may still pursue the other party. Primary and noncontributory wording is a related, separate request.
