    on with slightest pressure on the brake pedal. Turn signals may flash, however stop
    signals may not flash except when the vehicle is equipped with a brake warning system
    or device which will cause the brake lights to flash when the vehicle is in motion but
    committed to an emergency or panic stop;
  • 4. Motor vehicle was manufactured after January 1, 1955, and is not equipped with
    approved signaling devices (SAE-I);
  • 5. Vehicle is not equipped with a turn signal if such signal is not working properly or does
    not continue to function in the same manner as when it was originally manufactured.
    (The turn signal switch shall lock in place when positioned for a left turn or a right turn,
    and the turn signal indicators must function. Do not reject a vehicle if the self-cancelling
    mechanism in the switch does not function when the steering wheel is rotated.);
  • 6. Switch is not convenient to the driver and not of an approved type;
  • 7. Any vehicle so constructed so as to prevent the operator from making a hand and arm
    signal, if such vehicle is not equipped with an approved type signaling device;
  • 8. Turn signal lens is not clear or amber to the front, or red or amber to the rear. Lens or
    bulb color has been altered or modified. If the turn signal lens is clear, then the bulb shall
    be amber.
    NOTE: The pink color lens found on 1998 and 1999 Honda Accords emit the proper
    color light (amber) when the lamp is activated. There may be other manufacturers using
    the same configuration and are not in violation of the Federal Motor Vehicle Safety
    Standards;
  • 9. Wiring or electrical connections are defective or filaments do not burn.
    NOTE: LED light-emitting diode) lights with a clear lens are acceptable if of an approved

  • 10. Lens has a piece broken from it. The lens may have one or more cracks provided an
    off-color light does not project through the crack(s).
    NOTE: Tapping or gluing cracks or pieces is not permitted.
  • 11. The hazard warning signal operating unit does not operate independently of the
    ignition or equivalent switch and when activated cause all turn signals to flash

  • 12. Device is not mounted near the rear for rear signals or near the front for front signals
    (except supplemental turn signals) or if the signal is hidden by a bolster or other part of
    body chassis;
  • 13. All “Class A” signals are not mounted at least three feet apart. (This does not apply
