There is no full-time limit for subject 2, but some projects have time limits. The completion time of reversing and warehousing shall not exceed 2 10 seconds (counting from the reverse gear), otherwise it will be considered as unqualified in the exam. The completion time of lateral parking shall not exceed 90 seconds, otherwise it will be considered as unqualified. When the ramp is fixed to start, it must start climbing within 30 seconds after stopping.
