Safety apparatus for use in vehicles traveling on roadways. The apparatus including a vehicle with a computer having accelerometers and gyroscopes coupled to provide signals compensating for acceleration, velocity, and centripetal forces produced by movement of the vehicle. A color coded slope map stored in the computer. A simulated color wheel overlying a level bubble matrix within the computer with a fixed orientation relative to the vehicle. The matrix including a simulated bubble floating within the matrix, and the signals applied to the simulated bubble so that the position of the bubble and the color of the bubble is only dependent upon the orientation of the vehicle. The computer comparing or mixing the color of the slope map to the color of the bubble at each location along the slope map and providing a warning when the color of the slope map and the color of the bubble are compliments.
