Police in Victoria have impounded a motorcycle and issued hefty fines after a rider was caught speeding at nearly three times the posted speed limit earlier this week.

At around 8 p.m. PT Monday, traffic officers stopped a motorcycle driving at 140 km/h in the 2300-block of Blanshard Street, where the speed limit is 50 km/h, according to a police statement Tuesday.

The rider did not have a licence, and the motorcycle was not insured.

More than $1,300 in fines were issued and the motorcycle was impounded for a seven-day period.

Victoria police are reminding the public to obey the posted speed limits, despite there being fewer vehicles on the roads during the public health emergency.
