Share a topic about car driving safety - interval speed measurement.
To correct a misunderstanding, many people think that interval speed measurement is to measure the speed at the beginning and end points separately, which is wrong. By the time you receive the penalty notice, it's already too late.
Everyone understands the working principle of interval speed measurement and avoids fines for violations.
The basic principle of interval speed measurement is to take pictures of the vehicle at the start and end points respectively to record the time. When the vehicle reaches the end point of the interval speed measurement, the time is recorded again, and the average speed of the vehicle on this distance is calculated by comparing the time when the vehicle enters the starting point and the end point. If the average speed exceeds the speed limit, it is considered speeding.
For example, let's say there is an 8-kilometer stretch with a speed limit of 80 mph, and it takes 6 minutes to drive normally. If you reach the finish line within 4 minutes, then your average speed is 120 mph, which is over the speed limit.
At this point, the speed system will determine that you are speeding, and you will be deducted points and fined on your driver's license.
To avoid this, I recommend that you always pay attention to the speed limit signs on the side of the road while driving to make sure that your speed is in accordance with the regulations.
You can also understand the road conditions in advance through navigation software and plan the driving route reasonably.
