A training simulation system and method for detection of hazardous materials simulates real-world hazardous environments to provide a trainee with hazardous material training. The system provides a hazardous material detection simulator that displays simulated readings to indicate presence thereof. The detection simulator automatically generates the simulated readings, based on its relative position to the hazard point, and based on preprogrammed hazard points in the area. A host trainer, through a trainer communication device, remotely generates and adjusts the simulated readings while tracking vehicle's position. A vehicle integrally contains the hazardous material detection simulator. A trainee controls the vehicle while also observing and reacting to the simulated readings. Once the hazard point is determined, based on simulated readings, the trainee can form a decision on the readings and react accordingly. The simulated readings can be adjusted based on the reaction of the trainee and position of vehicle relative to hazard point.
