MOTORISTS using the M4 had to avoid an unusual traffic hazard yesterday a broken down tank.

The Warrior armoured personnel carrier blocked a lane at the top of the exit slip road, eastbound, at junction 26 for around an hour yesterday morning.

Traffic backed up for a short while as cars leaving the motorway were forced to slow down and pull out to avoid it.

Traffic Wales officers attended and managed the scene, and South Wales Fire Service also attended.

No-one from the Ministry of Defence was available to comment.
