In the simplest terms, single vehicle collisions are motor vehicle accidents that occur without the involvement of another car.

How Auto Insurance Companies Respond to Single-Vehicle Collisions

If you are at fault in the single-vehicle collision — for example, you lose control of your vehicle in icy conditions and hit a utility pole — then you’ll want to make sure you have collision coveragesaid Vartanian.

If you don’t, you’ll pay for the damage out of pocket. Liability cover may also cover some of your claim costs, but since you would be deemed at fault, you would want collision coverage in place to handle the rest.

Unlike liability or accident benefits, collision damage waiver is not mandatory coverage, with the exception of Manitoba and Saskatchewan. These provinces have public auto insurance, which includes collision coverage as part of the basic policy.

If your car is damaged by a flying object, however, full coverage would be your best protection, says Vartanian. In this case, you would not be at fault since the accident was beyond your control.

Be prepared for a premium increase in the event of a collision involving a single vehicle

The cost of your premium will depend on whether or not you are at fault in a single vehicle collision.

“As a rule, insurance companies will not increase your premium if [a single-vehicle collision] was the result of a tire flying off a truck and hitting you,” says Vartanian. “However, if you are driving and fall asleep at the wheel and hit a guardrail, your premium will increase.”

How much your premium increases will depend on your insurance company, as each has its own pricing formula, he adds. However, if you get a traffic ticket on top of the collision, it will likely increase your premium even further.

An at-fault collision can remain on your record for up to six years.

“With each passing year, the bounty blow would decrease. So if you are in the fifth year after the incident, your premium will not be as high as the first year after the incident,” says Vartanian.

Drivers can protect themselves against a premium increase, however, with Accident Cancellation Cover – an optional policy add-on that can ensure your premium isn’t affected after your first at-fault collision with that insurance provider. Other than that, there are practical steps drivers can take to reduce the risk of single-vehicle collisions, Vartanian says.

For example, drivers might want to avoid highway travel during rush hour when there are more trucks on the road and a higher risk of flying objects. Drivers should also try to avoid poorly lit roads at night if it is difficult to get a clear and full view of the road ahead. is a free, independent rate comparison website that allows Canadians to compare rates from over 75 providers for various financial products, such as home and auto insurance, mortgages and credit cards.
