There is heavy traffic in north Watford this morning, after a lorry stopped on the roundabout at the top of town.

Hertfordshire police were called to the junction of Rickmansworth Road and Beechen Grove at 9.20am, where a lorry was parked.

The driver revealed his "tachograph" device, which logs the number of hours driven, had run out due to heavy traffic.

The number of hours a lorry driver can spend behind the wheel is strictly governed by the EU.

The blockage is expected to be cleared by 9.40am.
