The Monarch Mark IA hand driving control incorporates the most popular method of operation, and undoubtedly the least fatiguing available. Through mechanical linkage, the brakes are applied by the forward motion away from the driver toward the brake pedal or dashboard. Again with mechanical linkage, the gas or accelerator is applied by a downward movement toward the driver’s lap and at a right angle to the brake. This quality hand control is our best seller and carries a 5 year limited warranty.
