Loaner Vehicle Agreement: What to Know During Your Repair

When your vehicle is in the shop after an accident, mechanical issue, or warranty repair, life doesn’t pause. You still need to get to work, pick up kids, run errands, and keep appointments. That’s why many repair facilities offer a loaner or courtesy vehicle—but before you drive off, you’ll almost always be asked to sign a loaner vehicle agreement.

From a customer perspective, the paperwork can feel like “standard stuff” you should sign quickly so you can get moving. But a loaner car contract can shift real financial risk to you if something goes wrong—especially around insurance coverage, responsibility for damage, prohibited uses, and return conditions.

This guide explains what a loaner vehicle agreement customer should know before accepting a courtesy car, what clauses matter most, and how to protect yourself while staying compliant with the shop’s rules.

What is a loaner vehicle agreement (and why is it required)?

A loaner vehicle agreement is a contract between you (the customer/driver) and the business providing the vehicle (typically a body shop, dealership, or specialty repair facility). It sets the terms for borrowing their vehicle while your car is being repaired.

A typical body shop loaner car contract covers:

• Who is allowed to drive the vehicle
• How long you can keep it
• Where and how it can be used (mileage, geographic limits, prohibited uses)
• Who pays for fuel, tolls, tickets, and cleaning
• Insurance requirements and what happens in an accident
• What counts as “damage” and how it’s assessed
• What fees apply for late return, lost keys, smoking, pets, or excessive cleaning
• The shop’s right to charge your credit card for certain costs

Even if the vehicle is offered as a “courtesy,” it’s still a valuable asset—so the shop needs written proof that you accepted responsibility under specific courtesy vehicle agreement terms.

Loaner vs. rental: why the difference matters

Customers often assume a loaner is basically the same as a rental car. It isn’t—at least not legally.

Key differences you may see

• Different insurance structures: Rental companies often offer optional coverages (LDW/CDW, liability options). Loaners may require you to rely on your own insurance first.
• Different policies and enforcement: A shop may have stricter limits on drivers, mileage, and return times because loaners are limited in number.
• Different damage standards: Some agreements require you to return the vehicle in the same condition, subject to a strict inspection.

Bottom line: treat a loaner with the same seriousness as signing for a rental—sometimes more.

The most important clauses in a loaner car contract (customer checklist)

Below are the provisions that most often create surprise costs or disputes. If you’re signing a loaner vehicle agreement customer form, scan for these items and ask questions before you leave the lot.

1) Authorized drivers: who can actually drive?

Many loaner agreements allow only the signer (and sometimes only drivers listed on the agreement). Others allow additional drivers only if they meet criteria like:

• Minimum age (often 21 or 25)
• Valid driver’s license
• Proof of insurance
• Clean driving record (sometimes)

Customer tip: If a spouse, roommate, employee, or teen might drive, get them approved in writing. If an unauthorized driver causes an accident, you may be personally responsible for the entire loss.

---

2) Insurance requirements: whose policy pays first?

This is the single most important part of most courtesy vehicle agreement terms.

Common approaches include:

• Your insurance is primary: Your personal auto policy pays first for collision/comprehensive and liability (subject to your deductible and coverage limits).
• Shop insurance is secondary or limited: The shop may carry coverage that applies only after your policy, or only in certain situations.
• You must carry certain limits: The agreement may require minimum liability limits or comprehensive/collision coverage.

Customer tip: Before you sign, confirm:

• Do you have collision and comprehensive on your policy?
• Does your policy extend to temporary substitute vehicles or non-owned vehicles?
• What deductible applies if the loaner is damaged?
• Will a claim affect your premium?

If you’re unsure, call your insurer while you’re at the shop. A two-minute call can prevent a costly misunderstanding later.

---

3) Responsibility for damage—even if it wasn’t your fault

Many customers are surprised to learn that a loaner car contract may make you responsible for:

• Any damage occurring while the vehicle is in your possession (even if parked)
• Diminished value (less common, but possible)
• Towing and storage charges after an incident
• Administrative fees related to processing claims

Even if another driver hits you, you may still have duties under the agreement (reporting, cooperating with insurance, getting a police report).

Customer tip: Ask what happens if the car is damaged while parked and the responsible party can’t be identified. That’s a common real-world scenario.

---

4) Mileage limits and geographic restrictions

Some loaners are truly “local use only.” Others include a set daily mileage (e.g., 50–150 miles/day) or a total cap.

You may see:

• A per-mile charge if you exceed the limit
• Restrictions on leaving the state
• Prohibition on certain roads or off-road use

Customer tip: If you commute far or have a planned trip, disclose it upfront and get written confirmation that it’s allowed.

---

5) Term, return date, and what counts as “late”

The agreement should specify:

• Start date/time and return date/time
• What happens if repairs take longer than expected
• When you must return it once your vehicle is ready
• Late fees (per day or per hour)

Some agreements require return within X hours of notice that repairs are complete.

Customer tip: Ask how you’ll be notified (text/email/call) and whether weekends or holidays affect deadlines. If you’ll be unavailable, communicate early.

---

6) Fuel policy: “same as received” is common

Many shops provide the loaner with a partial tank and require you to return it at the same level.

Customer tip: Take a photo of the fuel gauge at pickup and return. If the shop charges a refueling fee, those photos can help resolve disputes quickly.

---

7) Fees that can be charged to your card

Loaner agreements often authorize the shop to charge your card for certain items, such as:

• Fuel
• Cleaning (smoke, pet hair, stains)
• Lost key/fob replacement
• Toll charges or toll processing fees
• Parking tickets, moving violations
• Late fees
• Damage not covered by insurance

Customer tip: Read the authorization language carefully. If the agreement allows charges without additional approval, be sure you understand what triggers them.

---

8) Prohibited uses (these can void coverage)

Many body shop loaner car contract forms prohibit:

• Smoking/vaping in the vehicle
• Pets (or pets without protective measures)
• Ride-share or delivery driving (Uber/Lyft/DoorDash)
• Towing, hauling, or transporting heavy items
• Off-road driving or jobsite use
• Driving under the influence
• Using the vehicle for illegal activities

Customer tip: If you rely on gig work or use your vehicle for tools/materials, disclose that you need a vehicle suitable for that purpose—or confirm the loaner is allowed for your use.

What to inspect and document before you drive away

A few minutes of documentation can prevent a “he said/she said” later.

At pickup

• Walk around the vehicle and note all existing dents, scratches, cracks, and wheel rash.
• Take photos and a short video including:
  • Front, rear, both sides
  • Close-ups of any damage
  • Wheels/tires
  • Interior seats, dash, and trunk area
  • Odometer and fuel gauge
• Confirm that warning lights aren’t on and that the spare tire/jack are present if applicable.
• Make sure you receive emergency numbers and accident instructions.

At return

• Repeat the photos (same angles).
• Ask for a return receipt or written confirmation that the vehicle was returned in acceptable condition.

This step is especially helpful if the loaner is in a high-traffic shop environment where minor damage can occur in lots.

What to do if you get into an accident in the loaner

Most agreements require you to take specific steps. Even if the accident seems minor, follow the contract.

Typical requirements:

1. Call 911 if anyone is injured or if required by law.
2. Notify the shop immediately (they may have preferred towing or reporting steps).
3. Exchange information with the other driver and take photos.
4. File a police report if the agreement requires it (or if damage is significant).
5. Do not admit fault; provide factual statements only.
6. Cooperate with insurance and provide claim details promptly.

Customer tip: Keep the agreement in your glovebox or saved as a PDF on your phone so you can reference reporting obligations quickly.

---

Can a shop charge you for “normal wear and tear”?

This depends on the contract’s wording and the shop’s policies. A well-drafted agreement typically distinguishes between:

• Normal wear and tear (minor, unavoidable use) and
• Damage (scrapes, dents, stains, smoke odor, curb rash, cracked windshield)

However, “wear and tear” is subjective. A scratch might be treated as damage if it wasn’t present at checkout.

Customer tip: The more detailed the pre-inspection photos, the less room there is for disagreement.

---

Common customer pain points (and how to avoid them)

“My insurance didn’t cover the loaner like I thought.”

This happens when customers:

• Only have liability coverage
• Have high deductibles
• Have exclusions for non-owned vehicles (less common, but possible)
• Let an unauthorized driver operate the vehicle

Avoid it: Confirm coverage with your insurer and comply with driver restrictions.

“I returned it late because my car wasn’t ready.”

Sometimes the shop expects you to return the loaner when your car is ready, not when it’s convenient.

Avoid it: Ask for the exact trigger for return obligations and whether an extension is possible.

“I got charged for cleaning.”

Smoking, vaping, and pet hair are common triggers. Some shops also charge for excessive sand, stains, or food spills.

Avoid it: Treat the loaner like a “no food/no smoke” vehicle and use seat covers if transporting pets is allowed.

---

How to negotiate or clarify terms (yes, you can ask)

Even if the agreement is standardized, you can still ask clarifying questions and request written notes.

Consider asking:

• “Can you confirm my spouse is an approved driver?”
• “Is there a mileage cap? What happens if I exceed it?”
• “What insurance coverage is required, and do you have a copy of my insurance card on file?”
• “If repairs run longer, will the return date automatically extend?”
• “What is the late fee, exactly, and when does it start?”
• “What counts as chargeable damage vs. normal wear?”

If something is unclear, request that the staff member annotate the agreement or provide an email confirming the detail.

What a fair loaner vehicle agreement usually includes

While contracts vary by state and by business, a balanced loaner car contract typically includes:

• Clear identification of vehicle, VIN/plate, mileage, fuel level
• Condition checklist at check-out and return
• Reasonable driver eligibility requirements
• Clear accident reporting procedures
• Transparent fee schedule (late, cleaning, fuel, lost key, tolls)
• Insurance responsibilities described in plain language
• Privacy and data handling disclosure if the vehicle has telematics or GPS (increasingly common)

If your agreement is vague on key topics—especially insurance and damage responsibility—ask for clarification before signing.

FAQs: Loaner vehicle agreement customer questions

Is a courtesy car really “free”?

Often it’s free in the sense that there’s no daily rental rate, but you can still be responsible for fuel, tolls, tickets, cleaning, late fees, and damage—depending on the courtesy vehicle agreement terms.

Can the body shop run my license or require a credit card?

Yes. Many shops verify license validity, collect insurance info, and place a card on file to cover potential fees or damage.

What if I don’t have full coverage insurance?

The shop may deny the loaner, require additional deposits, or require you to purchase coverage through another channel (if available). Policies vary.

Can I take the loaner out of state?

Only if the agreement allows it. Many body shop loaner car contract forms restrict travel distance or crossing state lines.

What happens if my repair takes longer than expected?

Ask whether the loan period extends automatically or if you must sign an extension. Get it in writing to avoid late fees.
