Final answer:
The number of points for speeding 46 mph above the speed limit or in a construction zone varies by location, with this level of offense typically incurring significant points. Local DMV or relevant authorities provide specific details.
Step-by-step explanation:
The penalties for speeding, including the number of points added to a driver's license, can vary by state and locality. In many places, the points associated with speeding 46 mph and above more than a speed zone or construction zone can be quite significant due to the increased safety risks involved. Typically, this level of speeding is considered a serious offense and would likely result in more points compared to lower levels of speeding. To get the exact number of points for such an offense, it's important to refer to the local Department of Motor Vehicles (DMV) or the relevant authority in your area. Concerning the examples provided in the question, exceeding a speed limit by a small margin, such as driving 31 mph in a 30 mph zone, might not always result in a ticket due to speedometer inaccuracies and enforcement leeway, but more significant speed limit breaches such as driving 46 mph and above can lead to serious consequences. Law enforcement uses various methods to determine speeds, including radar and the examination of skid marks in the event of sudden stops.
