Government coming up with new laws main purpose isn't to make the roads safer. It's more income, especially when the Canadian Government are owing billions in debts.
The 40km/h or 50km/h over law doesn't makes sense at all.
Example:
Traveling 150km/h in a 100km/h zone (who hasn't done it?); that's 50% over the limit
VS.
Traveling 90km/h in a 40km/h zone (Never done so in my life); 125% over the limit.
If caught in either situation, you are violating the same law.
The law is like, you killed someone; you get the chair. You stole a loaf of bread to feed your family; you also get the chair.
Penalties for 50km/h over:
Towing charge: $250.00
Impound for 7 days: $700.00 ($100.00 a day)
6 demit points: max. $10K fine
Insurance: priceless.
