Y frawddeg yw:
The local authority (also known as the Highway Authority) have a duty 'to
assert and protect the public's
right to the use and enjoyment of
any highway for which they are the highway authority'
Beth yw 'assert' ac 'enjoy' yn y cyd-destun hwn, ogydd? A fyddai
'sicrhau' a 'mwynhau' yn gwneud y tro?
Diolch
