Regarding the question "Can you directly test the driver's license without driving school training?", The Transportation Administration of the Ministry of Public Security responded that China's laws and regulations do not require driving school training to apply for a driver's license, but they must learn driving skills on the road. According to the relevant provisions of Article 20 of the Implementation Regulations of the Road Traffic Safety Law, learning to drive on the road should follow the route and time specified by the traffic management department of the public security organ. To learn the driving skills of motor vehicles on the road, a coach car should be used. The coach is carried under the coach's guidance. Persons not related to teaching are not allowed to ride the coach. Based on the above information, which of the following cannot be derived? ['You can learn to drive on the road if you have a coach coach.', "Can't learn driving skills on the road without coaching guidance.", 'If a coach is only available at a driving school, you must first apply for a driving license.', 'If you have already applied for a driving license, you must have learned driving skills on the road.']
