Llywydd, can I thank Darren Millar for those very important follow-up questions? Fatalities in north Wales in September have been very distressing, and I know that he's been directly concerned with some of them. I wanted to thank him for the letter that he sent in to the Minister at the end of August, and I know he's received a reply from Ken Skates specifically regarding road safety on the A494, measures that the Welsh Government has already taken and which need to be monitored now for their effectiveness, but to give him an assurance, as the letter did, that, if those measures are not effective, then other measures will be considered of the sort that he has set out, so that we can do everything we can together to make sure that lives, and young lives, are not lost on roads in north Wales.
