A set of temporary traffic lights outside a supermarket in Sudbury are causing chaos for drivers. 

The three-way signals outside Sainsbury's in Cornard Road have been causing traffic issues since they were put in place on December 29. 

The AA Traffic Map is showing heavy traffic in the area with some people reporting queues of 20 minutes. 

The lights have also caused issues with drivers trying to get in and out of Sainsbury's. 

The traffic lights are expected to be in place until Monday, January 9.
