Michael McLaughlin of BC Highway Patrol."The vehicle successfully demonstrated that it can speed and that it fits on the back of a tow truck."The driver was issued a $483 excessive speeding ticket under Section 148(1) of British Columbia's Motor Vehicle Act for travelling more than 60 km/h over the speed limit.In addition to the fine, the vehicle was towed and impounded for seven days. While the driver is responsible for the towing costs, the registered owner is responsible for the impound fees.Police said the driver will also face at least three years of high-risk driver insurance premiums, bringing the total financial impact of the incident to nearly $2,500.The BC Highway Patrol said it did not know whether the driver ultimately decided to purchase the Toyota.
