Delayed Braking on Uphill or Downhill?
2 Answers
In the Subject 4 exam, braking on an uphill slope is delayed. Related information: 1. Introduction: Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. After the implementation of the "Ministry of Public Security Order No. 139 of the People's Republic of China", the Subject 3 exam was divided into two parts: the road test and an additional safety and civilization knowledge test, commonly referred to as "Subject 4", which assesses "driving ethics". 2. Expansion: Since this test is conducted after Subject 3, it is commonly referred to as the Subject 4 exam. Officially, there is no Subject 4. The test consists of 50 questions, presented in the form of case studies, images, animations, etc., with a full score of 100 and a passing score of 90.
As a long-time automatic transmission driver, I frequently encounter response issues on slopes, with uphill delays being more noticeable. Since climbing requires greater torque output from the engine, the automatic transmission sometimes delays gear shifts, especially when starting from a stop on a slope - the vehicle feels sluggish, as if lacking power. In contrast, downhill delays are less common, with more emphasis on speed control issues like delayed brake response or insufficient engine braking, which can lead to rolling. From personal experience, regular checks of transmission fluid and engine condition can improve such delays. For safety during hill starts, it's important to apply steady throttle input rather than sudden acceleration, and the anti-slip system plays a crucial role too. During mountain trips, I pay extra attention to engine sound and acceleration feel to prevent dangerous situations caused by delayed response.
