from Alberta transportation website. Demerit points last 2 yrs, not 3.
"When two years have elapsed from the date of a conviction, the number of points assessed for that conviction are removed from your record. Remember, the date of conviction is the date that you actually pay your fine or are found guilty in absence, not the date that you received the fine."
그리고 속도위반으로 걸리면 3점 벌점을 먹게 되는데, 벌점에 따른 보험료 영향은 보험회사마다 모두 규정이 달라서 직접 회사에 문의하셔야 해요. 어떤 경우는 한번만 속도위반해도 보험료 오느는 회사도 있다고 합니다.
