Mounties have impounded two new luxury vehicles for racing at twice the legal speed limit on the Sea-to-Sky Highway near Squamish, B.C.

A concerned driver called Squamish RCMP around 11 a.m. Monday after reporting seeing the high-end cars “blowing by.”

Cpl. Robert McDonald said a 2014 grey Maserati and a 2012 black Ferrari were spotted speeding and following each other closely northbound on Highway 99.

McDonald said the drivers, both repeat offenders, were warming up their tires in preparation for racing by weaving in and out of the fast lane.

“It was like they were on a racetrack,” he told CTV News. “It’s just like how racers zigzag on the track to lubricate the tires to give them more traction for racing.”

Traffic services say the luxury sports cars were clocked going 140 kilometres an hour in a 70 zone.

Both drivers slammed on their brakes and slowed to 80 kilometres an hour after being spotted by Mounties, McDonald said.

The male drivers, both in their mid-20s, were ticketed for excessive speeding, which is punishable by a fine of up to $500. Both cars were impounded for 15 days.

McDonald says the punishments don’t reflect their previous history of driving infractions.

“Unfortunately there’s no escalation on that scale of fines,” he said.

McDonald said RCMP will continue to impound vehicles when drivers are caught speeding.

“Speeding anywhere is dangerous, especially that kind of speed. It won’t be tolerated,” he said.

Auto publication Motortrend says a 2014 Maserati retails for between $102,000 and $140,000 and a 2012 Ferrari can sell for up to $257,000.
