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
