Which of the following can contribute to accumulating demerit points?

Driving under the influence of alcohol is a serious offense that contributes to accumulating demerit points because it poses a significant risk to public safety. The legal framework surrounding impaired driving is designed to deter such behavior due to the heightened danger it presents to the driver and others on the road. When a driver is caught operating a vehicle while impaired by alcohol, they face legal penalties that include not just fines but also the addition of demerit points to their driving record. This graduated system of penalties aims to promote responsible driving behavior and ultimately reduce incidents of road accidents caused by impaired drivers.

In contrast, parking legally, using turn signals carefully, and driving under the speed limit all demonstrate responsible driving behavior and do not contribute to accumulating demerit points. These actions are encouraged as part of safe driving practices that help maintain road safety for everyone.
