Looking at the front plate number to judge the safe distance on the highway is the simplest way.
When driving on highways, it is important to keep a safe distance from the front vehicle. As a rule, the minimum safe distance between two vehicles on the highway must be 100 m if traveling at a speed of 120 km / h in dry road conditions. There are many ways for the driver to estimate how much distance is between the vehicle and the vehicle in front (feeling). I want to share a simpler way:
The principle of 5 seconds, select a fixed point on the road (Point A), the front vehicle is skimming across point A, the driver behind recalls counting from 1 to 5 (counting slowly so that each number equals one second). Count to the 5th second that your vehicle has not arrived or is just near the point A is a safe distance.
Based on the sample distance sign on the right side to identify the actual distance between the two vehicles. In my experience, we only need to look at the license plate of the previous car (only applied during the day and normal weather conditions). This method is intuitive and easy to understand, reflecting a more accurate distance estimation.
Reading the number on the front plate means that the distance is not safe at this time.
Unreadable numbers on the license plates running in front are relatively safe distances.
The license plate in the front is blurred, completely unreadable, meaning a safe distance.
In addition to the side lane, we should also maintain a minimum distance of 100 m (absolutely should not run parallel or close). Because when the car in the next lane is in trouble our car will definitely be affected by the chain.
I wish you a safe driver.
