Stage 2 Lesson 6
~ Human Capabilities and Driving ~
1. Keeping Clearance to the Sides
When the brake is applied in response to danger, there is about 1 second of reaction time until the brake begins to take effect, so drivers must take this into consideration when driving.
Drivers cannot drive safely if they do not have a reliable awareness of information about road and traffic conditions. Most information can be obtained through observation, so sight is the most important of all human senses when driving.
If you move your eyes to look around while driving, you will not be able to focus your attention. For this reason, it is better to drive while staring at one point as much as possible.
Close objects become more difficult to see when driving at 60 km/h than when driving at 30 km/h.
Eyesight deteriorates when suddenly entering a dark place from a bright place, but does not change when entering a bright place from a dark place.
When you suddenly go from a bright place to a dark place, you can't see anything for a while, but eventually you can see little by little, which is called light adaptation.
Even at the same distance, small vehicles appear closer and large vehicles appear further away than they actually are. Even traveling at the same speed, objects appear faster at night than during the day.
2. Factors Affecting Recognition, Judgement and Operation
If driving for a long period, a driver should stop driving once every two hours and have a rest.
If drivers feel even slightly sleepy while driving at night, they should stop the vehicle in a safe location and take a nap or rest for a short time, resuming driving after they feel refreshed.
