What is the driver's field of vision when the vehicle is stationary?
1 Answers
When the vehicle is stationary, the driver's static field of vision is approximately 200 degrees. The relationship between vehicle speed and field of vision is as follows: When the speed increases from zero to 40km/h, the dynamic field of vision is about 100 degrees. When the speed increases to 80km/h, the dynamic field of vision is about 60 degrees. When the speed increases to 120km/h, the dynamic field of vision is only about 30 degrees. Generally, when the speed is below 50km/h, drivers can still clearly distinguish objects in front and on both sides. Generally speaking, as the speed increases, the dynamic field of vision narrows, and the clear observation distance shortens and moves forward. Therefore, it is advisable not to speed. Precautions for safe driving: Do not press the accelerator pedal forcefully before the engine coolant low-temperature warning light goes off. Insufficient heating can lead to abnormal combustion of unburned gases and damage the three-way catalytic converter. Before driving, always ensure all doors are closed, as unclosed doors may suddenly open during driving, causing serious accidents. If any door is not properly closed, a door ajar warning will appear on the dashboard. When snow or fallen leaves accumulate at the air intake under the front windshield, remove them promptly. Otherwise, fresh air cannot be drawn in, leading to insufficient ventilation inside the vehicle. During rain, the temperature inside the car rises, causing fog to form on the windows, which can impair the driver's vision.
