Arrest someone, fight with them, throw them in jail and see them through to penalty in criminal court seems to be business as usual for the police, but write someone a traffic ticket and it's like you've called their mother a bad name. Very few drivers hang their heads, apologize for their mistake and said hand over my ticket, I'll do better next time. Those people do exist and probably receive the benefit of a doubt more often but those that don't wind up asking me for dispute advice in the DriveSmartBC discussion forums.
Drivers who admit to an error are willing to pay the price of the ticket as long as they don't get any penalty points. This is often heard prior to the commencement of traffic court if the issuing officer makes inquiries among the disputants. The trouble is, if you plead not guilty and are found to be, the justice presiding has no control over penalty points. They are assessed by ICBC in response to the conviction.
