How can you tell if you are over the legal speed limit?

Observing speed limit signs and checking your speedometer is the most reliable way to determine if you are driving over the legal speed limit. Speed limit signs provide clear and legally binding information about the maximum speed allowed on the road you are traveling. Your speedometer is an instrument in your vehicle that accurately displays your current speed, allowing you to compare it against the posted speed limit.

Tracking the mileage of your vehicle does not provide information about your current speed relative to the speed limit, while judging the speed of other vehicles can be misleading and does not account for the posted limits unique to each road. Similarly, the sound of your engine may vary depending on many factors but does not give a precise measure of speed. Together, observing signage and monitoring your speedometer offer the most straightforward and accurate method to ensure compliance with speed regulations.
