Crystal Owen, mum of Harvey, is campaigning to introduce graduated driving licenses, which would place restrictions on new drivers aged between 17 and 19.
Senior coroner for north west Wales Kate Robertson said she would also be writing to the Department for Transport about the issue.
Mrs Owen told BBC Breakfast she was happy with the outcome from the coroner, but the government still needed to act.
If introduced, there would be a minimum six-month learning period and 17 to 19 year olds would be prohibited from carrying passengers under the age of 25, with some exemptions.
“Every young person will still be able to drive, it’s not stopping them from going anywhere, it’s just making sure they do it safely, and not being responsible for people’s lives when they’re at most risk,” she said.
