Which driving behavior is not penalized with demerit points?

Driving with a broken tail light is not penalized with demerit points because demerit points are typically associated with driving behaviors that directly impact road safety and are regulated under the Highway Traffic Act. The focus of demerit points is primarily on actions that demonstrate a disregard for traffic laws and can lead to accidents or unsafe driving conditions.

While having a broken tail light is certainly a violation and can result in fines or other penalties, it does not fall into the category of actions that affect the driver's ability to operate the vehicle safely in the same way that behaviors like speeding, unnecessary slow driving, or distracted driving through phone use do. The latter actions indicate a direct risk to both the driver and other road users, which is why they are assigned demerit points.
