Roadside alcohol breath testing during COVID

Convicted Driver Insurance
Good afternoon, are you able to give me any "general" insight into the attitude of police forces regarding road side breath testing during the COVID pandemic with respect to drivers causing serious injury to a cyclist especially in the early days - March/April 2020? Did it vary by police force? What was the view regarding safety of using breathalysers? We were told by the police that the driver who seriously injured our son was not tested because of COVID. I have searched for guidance but have not been able to find any apart from Scotland.
