your issue dated February 20, and that from Michael Joyce of February 27, there appears to be a certain degree of confusion about the procedure to be adopted when two vehicles approach a gap wide enough for only one vehicle to pass.
There are obviously two schools of thought; the first —headlights on and off, meaning "I am coming through ", and the second—headlights on and off. meaning "After you, Claude!" Personally, I am a member of the first school. In my previous letter on the code I pointed out that the trunker's signal for stop is the oil and on flashing of the tail light. In most wagons the tail light and the side lights are controlled by the same switch, so the signal to approaching traffic meaning " I am stopping" is the on and off blinking of the side lights.
In my opinion the use of the headlight seems to denote generally onward movement. Thus, "1 wish to overtake ", headlight flash; " You may overtake ", headlight flash; "Come on and keep going" brings in the use of headlight again. Therefore, to me, the flash of the headlight opposite an obstruction means " I am coming through ". I think that most trunkers will agree that this is the procedure on main roads at night. The confusion appears to arise only in daylight.
