Bicycles are very unstable vehicles. If we sound the horn near a cyclist, they may be startled, causing sudden movements and possible loss of balance. That is why you should avoid acoustic signals.
Remember that to overtake cyclists, both outside and inside built-up areas, we must maintain a lateral clearance of no less than 1.50 metres.
