What do 261, 145, and 520 mean in Subject One?
2 Answers
Subject One's 261, 145, and 520 are mnemonic techniques using numbers. The specific explanations are as follows: 1. Number mnemonic 261: When visibility on the highway is less than 200 meters, the speed must not exceed 60 km/h, and the following distance must not be less than 100 meters. 2. Number mnemonic 145: When visibility on the highway is less than 100 meters, the speed must not exceed 40 km/h, and the following distance must not be less than 50 meters. 3. Number mnemonic 520: And for visibility less than 50 meters, the speed must not exceed 20 km/h, and the vehicle should exit the highway at the nearest exit as soon as possible. Additional information is as follows: 1. Number mnemonics: Follow the memory principles of modern psychology, mainly utilizing imaginative association and object imagery memory techniques. 2. Imaginative association is the foundation of number mnemonics: The secret of number mnemonics lies in transforming numbers from abstract symbols into vivid imagery.
When preparing for the written test (Subject 1), I was most afraid of mixing up the numerical questions. '261' specifically refers to the speed limit of 30 km/h when crossing railway crossings, which must be strictly adhered to, otherwise, the sudden arrival of a train can be extremely dangerous. I was once fined for speeding at a crossing, so now I always slow down and ensure safety before crossing. Railway traffic rules are fundamental for protecting lives, and when getting a driver's license, you must engrave these details in your mind—no laziness allowed. '145' is about checking traffic lights and yielding to straight-moving vehicles when making a U-turn. Turning recklessly can easily lead to scratches or hitting pedestrians, so in daily driving, you must patiently wait for signal changes to ensure safety. '520' refers to reducing speed in rainy conditions, such as lowering the limit from 40 km/h to 30 km/h, increasing braking distance to prevent skidding or rear-end collisions. These small knowledge points may seem trivial but can save lives—don’t underestimate them. Failing Subject 1 is no fun, so practice more to get familiar with them.
