Human protection in cars has been the primary area of study in the past few years. A significant issue for groups of researchers and industrialists around the world is -crash-. Car users often overcome problems related to trapping in a car of car causing suffocation kind of problems, where immediate communication is very much essential. Similarly a problem often arises when it comes to the collision of vehicles from back side. This paper proposes a smart car personal assistant system that provides an efficient solution for the problems like collision detection, being trapped inside a car and also provides a necessary support by using IoT and Creation of an android application consisting of critical characteristics such as contact in the above potential problems, renewal of PUC, periodic expenditure of vehicle-related items, regular check-ups and maintenance, car database and user information of the car, which will minimize user efforts.
