A single minor speeding conviction can cause car insurance premiums to spike by as much as 50 per cent, according to a Windsor insurance broker. The warning comes amid rising concerns over the financial impact of traffic violations on drivers in Ontario.
Broker's warning based on industry data
Speaking to local media, the broker explained that even a minor infraction, such as driving 10 to 15 km/h over the limit, can lead to a significant rate increase. The 50 per cent figure reflects the average hike observed among clients with a first-time speeding conviction, though increases can vary depending on the insurer and the driver's history.
“Many drivers don't realize that a single ticket can double their insurance costs,” the broker said. “It's not just about the fine – the long-term impact on premiums can be far more expensive.”
How speeding affects premiums
Insurance companies classify speeding tickets as a sign of increased risk, leading to higher premiums for three to six years. In Ontario, insurers are allowed to consider convictions for minor traffic violations when setting rates. The broker noted that a conviction for driving 16 to 29 km/h over the limit typically results in a 15 to 25 per cent increase, but in some cases, the hike reaches 50 per cent.
Drivers with a clean record may see a smaller increase, while those with previous violations could face steeper penalties. The broker advised motorists to consider fighting tickets in court or taking a defensive driving course to mitigate the impact.
Broader context of rising insurance costs
Car insurance rates in Ontario have been climbing steadily, with average premiums exceeding $1,800 per year in 2025. Speeding tickets are one of the most common factors driving increases, alongside accidents and claims. The broker urged drivers to be cautious, especially in areas with frequent police enforcement.
“A moment of impatience can cost you hundreds of dollars a year for half a decade,” the broker added. “It's worth slowing down, not just for safety but for your wallet.”
