Modified vehicle.

Car insurance may sometimes seem like a mystery. Your premium is determined based on a variety of factors, including: the type of car you drive, your personal driving record and where you live.

As one of the most important factors is the type of car you drive, it should come as no surprise that your insurance company is quite interested if you modify your car. So, it’s very important to contact your broker or your insurance provider before you make any modifications to your vehicle.

If you’ve made a modification to your car without consulting with a broker or informing your insurance company, it’s possible that these modifications will impact your insurance policy and you may actually be driving uninsured.

Before hitting the road, stick around and learn more about car insurance specifically designed for your modified vehicle.

The Pros and Cons of Modifying Your Car

Customizing a car is an alluring prospect for anyone who wants to stand out in the crowd. Modifications can range from aesthetic changes, such as body kits, to performance enhancers, such as turbochargers. When expertly handled, some modifications can enhance the performance and market value of the vehicle.

Even when carried out by experts, performance modifications may void the warranty of your engine and could land you in legal trouble. Some mods, such as nitrous injection kits, are illegal in Canada. In some provinces, officers can pull a modified vehicle off the road if they doubt its roadworthiness and safety. If they do, they will ask for a certificate of inspection covering the modification.

Mods can also cause malfunctions in the vehicle and damage parts, which can ruin your vehicle or cause an accident. Based on the nature of the ‘cons’, there may either be no vehicle insurance coverage or premiums may be very high. If the modifications are done without your insurance company’s knowledge, it may be considered a violation of the policy conditions, and any claims you make may be denied.

Before having any customizations done to your vehicle, think hard about what you stand to gain and lose, and have a discussion with your insurance broker.

Why vehicle modifications impact insurance

There are two key reasons why modifying your vehicle can impact your auto insurance:

  1. It can affect the safety and performance of your car
  2. It can affect the overall value of your vehicle

When applying for insurance, you are required to provide details about the make and model of your vehicle. This information helps the insurance provider determine your coverage price.

Any modifications will impact the insurance company’s appraisal of your vehicle, which can influence your insurance policy. In some cases, the effect might be to increase your insurance premiums, but in the worst-case scenario, it could mean termination of your insurance policy.

Modifications impacting vehicle safety

If you plan to make any modifications to your vehicle to change how it performs, it’s vital to contact your insurance broker beforehand to understand how this could impact your policy. Changes that might impact performance and safety include:

  • Modifications to the engine
  • Modifications to the car suspension
  • Modifications to the brakes or braking system
  • Modifications to the vehicle’s transmission
  • Increasing or decreasing the tire size
  • Tinting the windows

Modifications such as lowering the suspension and altering the size and/or power of the engine are considered to increase the risk of the vehicle being in an accident. Most of the modifications listed will require you to seek a new insurance policy with an insurance provider that is willing to insure a modified vehicle – hence the need to speak with your insurance broker.

Modifications impacting the vehicle’s value

Unless explicitly stated in the policy, most standard auto insurance policies either do not cover aftermarket parts or only offer minor coverage for certain aftermarket modifications. This means that if you want to add a feature to your vehicle to increase its value -- such as an expensive aftermarket stereo, special exhaust system, custom paint job or fancy rims -- these additions may not be covered under your insurance policy and in some cases, they may even void your insurance policy.

If you’re planning to modify your car with aftermarket parts and want them to be covered, you may need to look for a new policy. Contact your insurance broker to discuss the details and find out what coverage is available for vehicles with the types of modifications you want to make.

Always notify your insurance broker about modifications

When modifying your vehicle or purchasing a modified vehicle, it’s imperative that you inform your insurance broker and the insurance provider about the modifications. This is a responsibility placed entirely on you; it’s not the duty of the insurance provider to inquire about or investigate modifications.

If you are in an accident in your vehicle and later it is determined by the insurance company that your vehicle was modified and you failed to inform them, your insurance claim could be denied, and your policy could be revoked, leaving you liable for the damages and the cost of the accident.

For customized vehicles with extensive modifications, it may be necessary to look for an insurance provider that offers specialized insurance coverage for modified vehicles, as standard insurance coverage will not cover the vehicle.

Car insurance for modified vehicles in Canada

Regardless of whether you've made upgrades to your car, having custom car insurance tailored to your unique needs as a driver and car modifications is essential to keeping you safe while behind the wheel.

How can I save on modified car insurance?

While driving modified vehicles can affect how much you pay for coverage, there are still a couple of methods you can use that could potentially help you save on some costs. When purchasing your coverage, keep the following tips in mind:

Bundle your policies

If by chance you already have another type of coverage in place, for example, pet insurance or home insurance, you can bundle your coverage for your modified cars with your existing coverage. Insurance providers often provide a bit of a discount to customers who have more than one type of policy with them.

Ask about discounts

Drivers, regardless of whether they have modified cars or not, can still qualify for certain discounts. Whether it be for replacing their tires in the winter or installing security features, there are, in fact, numerous savings you may be eligible for. So, don't hesitate to ask about these so you can cut down on your expenses.

Increase your deductible

While car modifications will likely require a higher deductible regardless, you may still be able to get a bit of a discount by increasing your deductible amount even further. Remember, the deductible is the amount you agree to pay at the time you file a claim. So, make sure that you are able to comfortably afford a deductible increase before doing this.

Pay for your coverage upfront

Drivers can also get a bit of a discount when paying for their insurance upfront rather than monthly. Insurance providers typically add a fee to those who pay monthly, as they need to process payments throughout the year. However, by paying for your policy in one go, you can remove these fees.

These modifications, in addition to the standard rate for young drivers insurance, could yield higher rates, which you'll need to take into account at the time you purchase coverage. The best thing you can do in this scenario is work with a broker and shop around for different quotes from various providers.

As such, if you make changes to your car in order to make it more accessible to your needs, there is a chance that your provider will take this into account while calculating your insurance costs.

The best cars for students really depend on your unique needs as a driver. That being said, because students and young drivers, in general, are more of a risk while on the road, purchasing cars that are reliable and inexpensive to repair is probably your best bet, rather than driving a car that has an after-market modification. Again, this is completely up to you. We recommend speaking with your parents or guardians and an insurer for more information on what you can expect to pay.
