Which distance is not included in the stopping sight distance?

Stopping distance does not include the starting distance. The following is an extended introduction: 1. Introduction to stopping sight distance: Stopping sight distance refers to the shortest driving distance required for a vehicle to stop when encountering an obstacle ahead while driving on the same lane. Stopping sight distance can be broken down into three parts for study: reaction distance, braking distance, and safety distance. Simply put, stopping sight distance is the shortest distance required for the driver to stop before discovering an obstacle. 2. Composition of stopping sight distance: Stopping sight distance consists of three parts: the distance S₁ traveled during the driver's reaction time, the distance S₂ traveled from the start of braking to the complete stop of the vehicle (braking distance), plus a safety distance S₀ (5~10m).

The stopping sight distance is primarily the minimum distance required for you to come to a complete stop in an emergency situation. It includes the perception-reaction distance from the moment you see an obstacle to when you react and press the brake, as well as the braking distance before the vehicle actually stops. However, it does not include the acceleration distance, as that pertains to the part where the vehicle accelerates from zero to driving speed during startup, which is entirely irrelevant in an emergency stopping scenario. Remember, this distance is calculated based on your speed, reaction time, and road conditions, and ignoring the acceleration part allows you to focus more on the essence of safe driving. It is advisable to leave extra space when driving on highways or in rainy or foggy weather to compensate for this omission, just in case. During regular driving practice, simulating emergency scenarios can help you better grasp this distance.

Stopping sight distance refers to the distance you can stop your car after spotting a hazard while driving, which includes the reaction time from seeing the danger to applying the brakes plus the actual braking distance. However, it doesn't account for the safety margin distance - that extra space you leave as a buffer. Because stopping sight distance is the theoretical minimum, while the safety margin provides additional cushion for slower reactions or slippery roads. I always make it a habit to leave extra distance when driving, especially on wet surfaces - never rely solely on that minimum calculated value. Regular maintenance of your braking system also helps prevent issues. After all, emergencies come fast, so safety should always come first.

Stopping sight distance refers to the total distance from reaction to complete stop during an emergency braking, consisting of perception-reaction distance and braking distance. However, it doesn't include acceleration distance, such as the vehicle's speed-up phase when starting, which isn't factored into the calculation. Novice drivers often overlook this point, mistakenly assuming the stopping distance covers the entire process, when in fact it only applies to stopping at the current speed. Remember that the faster the speed, the longer the stopping distance, and rainy conditions make it even more hazardous. During driving lessons, practice more brake tests to understand practical applications.
