Mae\u2019r terfyn cyflymder rhagosodedig o 20mya ar ffyrdd preswyl yng Nghymru yn rhan o gyfres o fesurau i hybu cymunedau \u2018hawdd byw ynddynt\u2019. Mae cyfyngiadau 20mya wedi\u2019u gweithredu mewn sawl lle yn y DU, ond byth ar raddfa genedlaethol. Bydd angen newid sylweddol mewn ymddygiad gyrwyr er mwyn i\u2019r cyfyngiad gael yr effaith ddymunol.<\/p>\n

Noda\u2019r adroddiad bod y rhan fwyaf o yrwyr yn honni eu bod yn cefnogi syniad y cyfyngiadau cyflymder 20mya, ond nid yw llawer yn cydymffurfio mewn gwirionedd.
