Where:
At the beginning of and at the entrances to any carriageway, lane, bridge, path, or tunnel where the use of pedal cycles is not permitted.
This sign is commonly placed on freeways, high-speed roads, or restricted areas designed exclusively for motor vehicles.

Purpose:
To prohibit cyclists from using that section of the road or path where their presence could pose a danger to themselves and other road users.
Roads with fast-moving or heavy traffic are not suitable for pedal cycles, as cyclists are more vulnerable and may obstruct the smooth flow of vehicles.

Action:
Cyclists must not proceed beyond this sign and should instead use alternative routes that are safer or specifically designated for bicycle use.
Motorists should remain cautious and vigilant, as some cyclists may ignore the prohibition and continue along the restricted route.
Ensure that you reduce speed and keep a safe distance if you happen to encounter a cyclist in a prohibited area.
