Tesco has begun rolling out a traffic light system at store entrances to help maintain distancing.
The lights control the number shoppers inside based on the store’s capacity and two-metre social distancing guidelines.
Tesco began rolling out the system last week but said it would take a few months to install across its whole estate.
Aldi became the first retailer to begin putting traffic lights at its store entrances in May, as a way of limiting shopper numbers.
In September, Home Bargains revealed plans to install lights at all 550 of its stores across the country.
Some Co-op and M&S Simply Food forecourt stores have also installed traffic lights at entrances.
“The safety of our customers and colleagues is our top priority. To help with social distancing, we are introducing a new traffic light system at store entrances which will tell customers when they can safely enter,” said a Tesco spokeswoman.
