A senior police officer says a ban on motorcycles from national parks in Wales might be one idea to cut the number of road deaths.

Chief Supt Geraint Anwyl Williams was speaking following two deaths in two separate crashes in Gwynedd on Sunday.
He said there was a "significant core" of bikers who ignored speed limits.
Chief Supt Williams of North Wales Police said a ban at particular times until the message got through was one idea which could be looked at.
Police are appealing for witnesses after two men died and another was injured in two separate motorcycle crashes near Trawsfynydd.
The first incident, involving two bikes, happened on the Bala to Trawsfynydd road at 1530 GMT on Sunday.
Later on the same road, a motorcyclist was airlifted to hospital after another crash.
North Wales Police said those involved were from the Maidenhead, Berkshire, and Stoke-on-Trent areas.
However, they could not confirm which rider was from where.
The A4212 was closed for a short period for police to conduct an initial investigation at Blaen Cwm but was later reopened.
The injured biker from the second crash is in a stable condition in Ysbyty Gwynedd hospital at Bangor with shoulder and chest injuries.
Chief Supt Williams described the deaths as "more unnecessary waste of life, tragic."
He said police had put an awful lot of resources into reducing the number of motorcycle deaths, but there was still a small group of riders who were not taking the safety message on board.
This coupled with an increase in the number of motorcycles on the roads meant the police had now "reached a point where we really have to start thinking outside the box" he said.
Although various education programmes targeted responsible motorcyclists, there was "sadly a significant core" who visited north Wales and other areas, intent on speeding.
Tactics used by the police would have to change, he added, with covert means used to trap speeding motorcyclists who were "blighting" the weekends of other road users.
