Carrec

The carrec.img file stores path information used by the mission script for San Andreas only. The information it stores are location of vehicle, rotation of vehicle, and rotation of wheels. Not much is known about this file. These paths are predefined and look unnatural during gameplay because the movement of the vehicle is very rigid. The paths ignore many stuff in the game including gravity and obstacles.

Mission Script

You can use the following opcodes to do stuff to your paths.
07C0 - Loads the path
07C1 - Checks if the path has been loaded
0873 - Releases the path from memory
05EB - Assigns a vehicle to the path
0705 - Assigns a vehicle to the path

05ED - Freezes the vehicle along the path
05EE - Unfreezes the vehicle along the path
06FD - Sets the speed of the vehicle along the path
0706 - Advances the vehicle along the path
060E - Checks if a path is assigned to the vehicle
If you load a non-existant path to a vehicle, path 1 will be loaded instead.
