What is the standard dimension for a 90-degree turn in the C1 driving test?
2 Answers
The standard dimension for a 90-degree turn is the wheelbase plus 1 meter. For training vehicles (typically Santana models), the C1 test vehicle dimension follows the same rule: wheelbase +1m. Santana specifications: length 4546mm, width 1710mm, height 1427mm, wheelbase 2548mm. The C1 driver's license permits operation of: small and micro passenger vehicles; light and micro cargo trucks; light/small/micro special purpose vehicles; passenger vehicles seating ≤9 persons. Vehicles excluded from C1 license: large buses, tractors, city buses, medium buses, heavy trucks, regular trikes/motorcycles, mopeds, wheeled machinery, trolleybuses, trams. Additionally, C1 prohibits vehicles with >9 seats or trucks exceeding 6m total length.
I just got my C1 driver's license and remember the dimensions of the right-angle turn section very clearly. The lane width is 3.5 meters, equivalent to the standard width of urban alleys, and the entrance straight section is about 15 meters long, providing enough space for a smooth start when driving in. During the test, if the speed is too fast or the steering wheel is turned too late, it's easy to cross the line. The dimensions are ingeniously designed to simulate real driving challenges. When practicing, I used the lane width as a reference point—when the front of the car covered the corner, I turned the wheel sharply. The dimensions aren't arbitrary; national standards require consistency to avoid difficulty variations. I crossed the line a few times at first, but after getting familiar with the dimensions, I passed. Remembering this width and length can improve the pass rate. After passing, I realized this practice is very useful for daily narrow-road turns.
