As well as the calls that function in tandem or in place of signals, here are others that rely solely on clear vocal communication.
Used when attempting to join the flow of traffic from a junction to indicate that the road is clear and the group can begin to move through the junction without stopping but, crucially, after slowing to check for traffic. As a result, this call should only be used when the junction offers a clear line of sight in both directions.
The absence of this call indicates the default position that a vehicle is approaching, and that it’s unsafe to pull out of the junction or across the split road. Some riders also use a “car left/right” call to emphasise the presence of traffic in this situation, but make the call loud and understandable so not to confuse “car” with “clear”.
“On your left/right”
For use between cyclists, this warns a rider in front of you where you are in relation to them on approach. For example, calling “on your right” as you approach a slower cyclist from their right flank, and vice versa.
Used to warn of a car approaching the front of the Peloton, usually actively travelling towards the group. This is sometimes referred to as up the road, hence ‘Car Up’ is often used, but for simplicity Car Front is preferred.
This call is used when the road is narrower than a dual-direction single carriageway ie there might not be enough space for vehicles to pass each other without avoiding action (taking into consideration the formation of the Peloton)
Warns of a car approaching from the rear of the group, which means it’s also the only call which originates from the rear of the group. As a result, it’s vital to call clearly so that other group members hear and pass it up the line as your voice won’t travel as far forward against the flow of the bunch
Note: “Car” should be used consistently, with no requirement to modify the call for the type of vehicle approaching (as this can lead to confusion).
