Abstract: The driver training aid comprises a base, a steering wheel and steering gear of the type found in actual motor vehicles and a variable resistance spring assembly providing simulated resistance of the type encountered over the travel of an actual steering assembly. The variable resistance spring assembly comprises the spring arm fastened at one of its terminal ends to the worm gear shaft of the steering gear, an arcuately spring carringing rod fastened at its terminal ends to the gear housing with the geometrical center thereof being congruent with the center line of the worm gear shaft, and a spring slidably carried on and having its terminal ends secured to the spring carrying rod. As the steering gear reaches the extreme of its travel, the spring assembly is operable to apply increasing pressure to simulate pressures and resistance found in operational steering gears.
