CAN CHILDREN CYCLE ON PAVEMENTS?
According to the Department for Transport (DfT), the maximum fine for ‘cycling on the pavement’ (ie footways) from the courts is £500. However it is more usually enforced by way of the Fixed Penalty Notice procedure (FPN) which carries a £30 fine if pleading guilty. However, there is a view that the FPN can only be issued to those over 16.
“The DfT view, from discussions with Home Office, is that the law applies to all but the police can show discretion to younger children cycling on the pavement for whom cycling on the road would not be a safe option.”
The age of criminal responsibility is 10 so, technically, only children below this age can cycle on footways without fear of redress.
While adults are not allowed to cycle on ‘footways’ (see definition above), children up to the age of 16 cannot be prosecuted for doing so
Tell them that if the police can exercise discretion so should they.
