Delayed microphone keying and calling order results in confusion on resource roads

Location: 
Princeton, BC area
Date of Incident / Close Call: 
2012-02-08
Company Name: 
Gorman Bros.
Details of Incident / Close Call: 

A logging truck driver was calling kilometres in the following manner:

Kilometre - Direction (i.e. Up or Down )- Road Name

The driver delayed in pressing the microphone key so that what was audible on the radio was:

Direction (i.e. Up or Down) - Road Name*

This resulted in confusion to other drivers as the kilometer called was not heard over the radio.

This problem has been observed on other roads when there is a delay in keying the microphone and the kilometre is called first.

*Due to the high truck usage the radio use procedure in place specified that the ‘Road name’ be dropped temporarily to minimize chatter and increase safety. This practice was being followed.

Learnings and Suggestions: 

Calling km’s first seems to be a common practice but is no longer recommended. Following recommended guidelines for radio use on forest service roads is recommended. The provincial Forest Road Radio Protocol recommendation is to call km’s in the following manner:

Road Name – Direction (i.e. Up or Down) - Kilometre -– Vehicle Type and number (Optional)

A similar practice is recommended within the Okanagan TSA:

Road Name –- Kilometre -– Direction (i.e. Up or Down) -Vehicle Type and number (Optional)

If there is a delay in pressing the microphone key the kilometre number and direction are more likely to be heard using either recommended practice than if the km is called first as has been the historical practice.
