Tachographs are used in vehicles for keeping track of driver's hours and for other purposes of fraud detection, over speeding and accident investigation. Their usage and benefits are in danger because of increasing levels of frauds and manipulation. Tachograph fraud and tampering has become very common due to which the driver's hours and speed regulation are spurned on a large level. Most of these frauds are stimulated by economic pressure on vehicle operators and can be reduced if improved tachograph systems are introduced. Tachographs are used in vehicular environments. Vehicular communication networking is a promising approach to facilitate traffic management, road safety and infotainment dissemination for drivers and passengers. With the advancements in vehicular ad hoc networks, transportation safety and efficiency are at stake.
