How wide does a 4.7-meter sedan need for a 90-degree turn?

[JulianRose]

The width of a one-way road should not be less than 3.5 meters. Below is relevant information about right-angle turns: 1. Overview: A right-angle turn is an assessment point in Subject 2 of the driver's test, evaluating the driver's ability to correctly operate the steering and accurately judge the inner and outer wheel differences when driving through abrupt road changes. Engage first gear, release the handbrake, slowly lift the clutch to maintain semi-linkage and move forward at a steady speed. Keep the left wiper's left dot (the first rivet) on the car aligned with the yellow line on the right edge of the road at a 20 cm distance while moving forward. Then, focus on a point slightly ahead of the middle door lock on the left front door of the car. 2. Deduction points: If the wheels touch the protruding point, it results in failure; each time the wheels touch the road edge line, 20 points are deducted; if reversing is used to complete the task, 10 points are deducted; failure to use the turn signal or incorrect use of the turn signal results in a 10-point deduction.
