The new speed limit is set to be enforced after a three-and-a-half month "bedding in period".

The new 20mph default speed limit in built-up areas in Wales will start to be enforced this month.

The Welsh government has confirmed the £34m law, which came into effect last September, will be enforced in January after the “initial bedding in period”.

But ministers have said not all drivers breaking the 20mph (32km/h) limit will initially be prosecuted, just the most dangerous offenders.
