Published on: July 24, 2025

Exempt mileage title indicates that mileage data is unavailable for specific reasons, which means that you purchase it at a lower price and enjoy other benefits while stepping into unfamiliar territory. Since the reasons for this title status vary, each case is individual. However, it is unarguable that mileage data plays a crucial role for all potential vehicle buyers; hence, verifying a genuine mileage is always the number one priority.

In the US, federal and state laws require car owners to disclose their current odometer readings when selling their cars. The law aims to increase buyers’ trust and protect them from potential odometer fraud. This is where exceptions appear. It’s not mandatory for all vehicles. Additionally, it is beneficial for buyers if they diligently research the automobile before purchasing.

In the blog below, we will define federal and state laws, explain when this status is assigned, discuss its impact on resale value, identify situations that may lead to buyer untrustworthiness, and outline circumstances that may indicate odometer fraud.

What is exempt mileage?

Exempt mileage refers to the vehicle title, which indicates that it reaches its mechanical limits and the odometer no longer displays genuine data. The concept comes from Federal Odometer Act (FOA), enacted in 1972, as it aimed to protect consumers from fraud. Department of Motor Vehicles (DMV) requires sellers to disclose odometer readings except for the owners of the vehicles, who are exempt from disclosing. Firstly, it was 10-year-old or older vehicles that were exempt, however , since January 1, 2021, NHTSA slightly changed the rule, vehicles became exempt from disclosure after 20 years of their life, and this only applies to models produced in 2011 or newer. In other words, today, 2010 or older models are automatically free from disclosing, and 2011 or newer models become exempt, each after 20 years. Let’s illustrate in examples:

Model year Will become exempt and remain for a lifetime
2011 2031
2012 2032
2013 2033
2014 2034

So, the pattern continues the same for all consecutive years. Most US states follow the federal rule and they enforce the law accordingly. States as Texas, Florida, California, Colorado, Missouri, and Alabama assign an exempt mileage status to the automobiles that are entitled to this status according to federal law. However, there is a slight difference in the enforcement of this rule. For example, some of them have stricter rules, request disclosures anyway, implement their own electronic odometer disclosure systems, and have very strict penalties for odometer fraud. In short, each state has additional requirements that don’t exist in Federal laws.

When does it apply?

The title can be assigned to the automobile in several situations. Some of them may become reasons all at once, or each one individually. Here they are:

  • The car odometer reaches its mechanical limits. 99,999 miles is the limit it can reach and then it no longer display accurately.
    The automobile falls into special categories, such as HDA, RV, diplomatic, trailer, or antique.
  • Speedometer/Odometer replacement may lead to an inappropriate mileage reading and may be exempt due to incorrectness. Additionally, a broken odometer that doesn’t work properly is unable to show genuine data.
  • Odometer rollback makes it unable to get the correct mileage information, which may lead to this title.
  • Vehicle age: An aged vehicle automatically falls into the category that makes it free from odometer disclosure.

Is the lack of mileage data a red flag for used car buyers?

No, it is not always like this. Buying a car with exempt mileage status can be beneficial at some level, but it also includes potential risks. It depends on the buyer’s goal, budget and what they expect from the purchase. For some individuals, the goal is to purchase a classic car or a buyer is a collector; in this scenario, it’s quite acceptable and not surprising if odometer data is not available. Moreover, it would be strange if it were the other way. To be more precise, let’s write down the pros and cons of purchasing such a vehicle:

Pros

  1. Affordable price:those cars are unarguably cheaper. Affordability is the most attractive characteristic of cars that don’t have verified mileage. If you have a restricted budget and don’t care about the car’s age it’s a high chance that non-disclosed mileage is no longer a problem.
  2. Slowed depreciation: it’s an “unwritten rule “of depreciation that a newer car will depreciate slower than old cars with high mileage.
  3. Classic car: Classic cars have their historic values, and they are outstanding for their reliability and longer lifespan. Classic car lovers and enthusiasts can freely enjoy their automobiles, and they also have the benefit of being free from odometer reporting. There are a lot of rankings where older cars are highly appreciated, and they have recorded unbelievable miles throughout their lifetime. TopSpeed. Com delivers a list of overlooked American cars built for longevity. Some of the impressive models are:
  • 2015 Chevrolet Malibu with highest 189,765 miles
  • 2003 Buick LeSabre with 216,000 miles
  • 2010 Ford Taurus with 205,000 miles

Cons

  • High risk of odometer fraud: unverifiable mileage includes the risk of odometer fraud, as you have no guarantee that the owner hadn’t rolled back the odometer before the exemption. Exempt mileage is a comfortable solution for most individuals to hide this manipulation.
  • Unknown mileage information: Unknown mileage makes it unable to have a clear understanding of the existing condition of the car components. It makes it impossible to calculate the right time for scheduled maintenance. Hence, you missed the time for maintenance and replacement which leads to potential breakdown of the automobile.
  • Potential mechanical issues ahead: The danger of unforeseen mechanical issues is real. When you can’t asses the condition of the automobile, you are unable to determine potential upcoming problems.
  • Problematic resale/ hard to value it: Unless you find a person who prioritizes such cars and completely accepts it, it becomes a problem to “get rid of “this car. On the other hand it’s very hard to evaluate it and put the price. Without mileage data, it is not possible to make comparisions on the website like Kelley Blue Book or Edmunds.

How can the buyer’s trust be secured even this time?

Buyers will trust you if you share information honestly and particularly follow these tips:

  1. Mileage status. (as far as you know);
  2. Offer Vehicle History Report (like Carfax);
  3. Provide a complete service log from a trusted mechanic;
  4. Recommend/encourage an independent third-party inspection;
  5. Don’t hesitate to share ownership history;
  6. Provide all the necessary documentation;

So, when you don’t offer clear mileage data, you can compensate for it by providing and offering everything you can to build and secure trust. In this case, the buyer will be eager to make a purchase confidently.

Is vehicle resale value always affected by the ultimate high mileage?

The short answer is – Yes. Vehicle resale value is highly affected. We found some picks for comparison on KBB (an American vehicle valuation and automotive research company) , and we selected the same maker and model with a difference in years and miles. The comparison displays several trends:

  1. Even new models depreciate significantly due to mileage for a short period. Older cars with significantly high mileage keep their value.
    Toyota Prius LE 2024 – 25,040 miles – $ 27,500
    Toyota Prius Limited 2024 – 39 miles – $37 091
    Toyota Prius Four 2015 – 88,819 miles – $16,500
    Consider that the 2025 Toyota Prius MSRP is $29,485–$37,900.
  2. There is a big price gap between models before 2010 and after 2020.
    2009 Ford Edge SEL 74,663 miles – $7,499
    2024 Ford Edge SEL 17,119 miles – $32,837
    Consider that the 2024 Ford Edge MSRP is $39,960- $48,700.

Those are particular numbers and estimated prices; We consider mileage and years factors only to illustrate gaps. Surely, the automobile is estimated to have a lot of components, but it is unarguable that mileage data is crucial. The absence of this data can be an alert of potential odometer fraud.

The danger of odometer fraud is Real

Odometer fraud is not only a hidden danger behind exempt mileage, but it is also a common form of consumer fraud that costs billions of dollars annually. According to the definition of NHTSA, it is the disconnection, resetting, or alteration of a vehicle’s odometer with the intent to change the number of miles indicated. It is often called “busting miles” or “clocking”. This illegal practice is damaging for consumers as it’s quite hard to reveal when purchasing the car. Protecting yourself from odometer fraud begins with detecting it in a timely manner, when you are evaluating the condition of the automobile before making a purchase. Requesting the car title, requesting maintenance and service records, assessing the condition of components, examining the tires, and requesting a vehicle history report – all of these are essential steps that help reveal potential odometer tampering.

Test the newly purchased vehicle with an advanced tool

Purchasing a car with exempt mileage means you have a lack of mileage information. Hence, you don’t have one of the major criteria that would help to plan maintenance and pre-determine upcoming mechanical issues. In this situation, the best solution is to test and detect possible issues yourself or take your car to the mechanic routinely. Visiting mechanic often is quite tiring and time consuming, instead of this, you can pick advance testing tools, that is safe and reliable to use. One of the best quality testing devices is the Mileage Blocker.
