Abstract: An automobile protection system with road information indication mainly comprises a road information indicator installed in a car and a road information integration system linked to the road information indicator by a wireless communication means. The road information integration system is managed by a system manager, whereby the car driver can acquire road and car information at once. At the same time, the driver can pass the road information to other drivers. Thereby, the car driver and others can dodge traffic jams and reach a destination quickly, saving time and fuel. Further, an anti-theft interface of the road information indicator can detect the car conditions and report to the car owner's controller via the road information integration system.
