Rydw i wedi trafod y mater hwn gyda phedwar Prif Gwnstabl yr Heddlu yng Nghymru ac rwyf ar ddeall nad oes patrwm penodol i'r digwyddiadau trasig hyn. Fodd bynnag, mae'r heddlu yn parhau i gadw llygad barcud ac yn mynd i weithio gyda'r holl awdurdodau priffyrdd ledled Cymru i graffu ar y data. Drwy hyn, bydd modd gweld sut y gellir targedu'r ymyriadau yn fwy effeithiol.
I have discussed this issue with the four Police Chief Constables who have advised that there does not appear to be a particular pattern to these tragic incidents. However, the police are continuing to be vigilant and will work with the all highway authorities across Wales to scrutinise the data for indications of where interventions can be more effectively targeted.
