Eighteen vehicles collapsed on the Meida Expressway, killing 24 people and injuring 30 others. What is the reaction time of a person when driving at high speed at night in an accident?
Although accidents occur at night, tragedy can be avoided if drivers can concentrate and react quickly and brake in time when they notice a road problem.
The reaction time of an accident is different for each person, and is related to the individual's reaction speed, emotional state, concentration level, driving skills, and vehicle speed. The normal rapid reaction time is 0.5-1.5 seconds.
If driving at a speed of 100 kilometers per hour, the vehicle can advance 13.8-41.5 meters in a reaction time of 0.5-1.5 seconds. When the brain reacts quickly, the braking system operates, and the reaction time of the braking system is generally between 0.2-0.5 seconds. So, the overall reaction time is between 0.7-2 seconds. Vehicles can advance between 19.4-55.4 meters.
When driving at night, the driver's visibility distance is limited by the range of car lighting, street lighting, driver's eyesight, climatic conditions, etc., and the visibility range is generally about tens of meters to more than 100 meters.
Therefore, if the driver is alert enough to concentrate on driving at night, when an accident is found ahead, emergency braking is carried out, and driving at a speed of 100 kilometers per hour can mostly be effectively braked to avoid accidents.
When driving at night, you should pay attention to keep a clear head, avoid staying up late and excessive fatigue, pay attention, use high beams, and the driving speed is best controlled within 100 kilometers to be safer. #梅大高速失联五人不在医院收治名单#
