(A) When TSPS is being used by an emergency vehicle responding to an emergency situation, standard light and siren operation should be followed in accordance with department policy.
(B) When TSPS is being used in an emergency situation where the use of sirens is not appropriate, standard emergency light operations should still be used. Increased caution and reduced speeds, particularly at intersections, are then required.
(C) Emergency personnel must be aware that TSPS may fail to provide right-of-way at all signalized intersections due to the following:
(1) The intersection may not be TSPS equipped;
(2) One or more TSPS components may be inoperative;
(3) The speed of the emergency vehicle may cause the emergency vehicle to arrive at the intersection too soon for TSPS to cycle the signal to green;
(4) Another emergency vehicle using TSPS may be coming from a cross-flow direction and may already have seized command of the intersection signal;
(5) Severe weather conditions may disrupt the detection of the emitted signal, thereby preventing TSPS from recognizing the signal preemption request;
(6) Other conditions may exist which prevent TSPS from operating as designed.
(D) Upon reaching the emergency destination, TSPS emitter shall be turned off immediately to insure that it does not inadvertently seize control of surrounding signalized intersections.
(E) Whenever TSPS appears not to be functioning properly, it is the driver’s responsibility to immediately report the defect and the location of the defective signal to Apple Valley Police Dispatch.
