Signaling Your Maneuvers Clearly: Indicator Regulations for Motorcycles at Ausmec Mobile RWC & Mechanics

At Ausmec Mobile RWC & Mechanics, we understand the importance of clear communication while riding your motorcycle. Properly functioning and compliant turn signals (indicators) are essential for informing other motorists of your intended direction changes, preventing accidents. Here's a breakdown of key Queensland Department of Transport and Main Roads (TMR) regulations ( regarding motorcycle indicators:

Indicator Requirements Based on Manufacturing Date:

  • Pre-ADR 19 Compliant Motorcycles (Manufactured Before July 1, 1975): These motorcycles are not required to have indicators.
  • Motorcycles Manufactured Between July 1, 1975 and October 1, 1991: Indicators are mandatory, but they don't need to comply with ADR 19 specifications.
  • Motorcycles Manufactured After October 1, 1991: Indicators must comply with Australian Design Rule (ADR) 19 regulations. Older motorcycles can be modified to meet ADR 19 standards, but all ADR 19 requirements must be fulfilled. Partial upgrades are not permitted.

Pre-ADR 19 Indicator Requirements:

  • Minimum Separation: Indicator lights on each side of the motorcycle must be at least 300mm apart for optimal visibility.
  • Height from Ground: Each indicator must be positioned at least 350mm above the ground level.
  • Flashing Pattern: When activated, the indicators must produce regular flashes at a rate between 45 and 120 flashes per minute.
  • Activation Signal: The indicator system must be wired to an audible or visible device that alerts the rider when the indicators are engaged.
  • Color and Synchronization: Front-facing indicators must be white or yellow, while rear indicators must be yellow or yellow and red (if pre-1973). Indicators on the same side of the motorcycle must flash simultaneously and at the same rate.

ADR 19/00 Compliant Indicators:

  • Front Indicator Placement: These indicators must be at least 300mm apart and positioned at least 100mm away from the headlight for proper light distribution.
  • Rear Indicator Placement: Rear indicators on ADR 19/00 compliant motorcycles must be at least 240mm apart.
  • Height Allowance: ADR 19/00 indicators can be mounted between 350mm and 1200mm above the ground level.
  • Color Requirement: All ADR 19/00 compliant indicators must be amber in color for clear visibility.
  • Flashing Rate and Compliance Markings: The flashing rate must be between 60 and 120 flashes per minute. The indicators must also display compliance markings (e-mark) as shown in the example below. 
  • E-mark on a motorcycle
  • Tell-Tale Indicator: The system must incorporate either a green operating tell-tale light, an audible warning sound, or both, to inform the rider when the indicators are activated.

ADR 19/02 Compliant Indicators:

  • Variations on Front Indicator Placement: ADR 19/02 allows for a minimum separation of 240mm between front indicators. The minimum distance from the headlight depends on the indicator intensity as outlined in the table below:
Minimum indicator intensity (cd) Minimum separation (mm)
≥ 90 75
≥ 40 175
≥ 20 250
≤ 20 400
  • Rear Indicator Placement: Similar to ADR 19/00, the minimum separation for rear indicators is 180mm.
