Strategy Behind the Standard
Traffic signals are typically installed at busier junctions where facilities that separate and protect cyclists from motor vehicles will normally be required.
A standard traffic signal head can be used to control traffic consisting solely of pedal cycles. This signal includes green and amber cycle aspects and, following the publication of TSRGD (2016), can incorporate either a full red aspect or a red cycle symbol aspect. Signals can be either high level or low level.

How the Standard Should be Applied
High-level cycle signals (HLCS) may only be used to control a cyclist-only movement on a segregated cycle track or approach to a junction.
A low-level cycle signal (LLCS) may be used:
- On their own to signal segregated cycle movements.
- As repeater signals mounted on the same post as traffic signals to TSRGD diagram 3000.
- As repeater signals mounted on the same post as full size cycle signals to TSRGD diagram 3000.2; or
- As an early release function mounted on the same post as full-size cycle signals to TSRGD diagram 3000.
Where the use of LLCS is proposed, any existing signal equipment will need to be checked to ensure it is using Extra Low Voltage (ELV) and that the signal aspects are LEDs. Older installations may require equipment upgrades.
