A new law brought onto force on Monday means people who risk spreading coronavirus can be fined up to £10,000.
Police officers, PCSOs, council marshalls and others can hand out the fixed penalty notices for a number of offences.
The main offence is breaking self-isolation rules - leaving the house when you have been told not to by a member of NHS Test and Trace or another authorised person.
People will be told to self-isolate if they have Covid symptoms or have been in contact with someone who does.
But there are other rules within the new law that also come with a heft fine.
That includes lying about someone else potentially having coronavirus.
The Health Protection (Coronavirus, Restrictions) (Self-Isolation) (England) Regulations 2020 rules introduced on Monday, September 28, states: "A person who knowingly— (a)gives false information pursuant to regulation 2(2)(a)(ii), (b), (c)(ii) or (d); or (b)falsely states, when asked by a person specified for the purpose of regulation 2(4), to that person that someone is a close contact of a person who has tested positive for coronavirus, commits an offence."
In short, that means that if you say you have been in contact with someone and could have infected them with coronavirus, when you haven't, you can be slapped with a fine - starting at £4,000.
If you refuse to pay the fine you can be taken to court - and end up with a criminal record.
It is also an offence to 'recklessly' put someone at risk of catching coronavirus through close contact.
And it is an offence to obstruct anyone trying to enforce the new coronavirus law.
The new law also says an employer must not allow an employee to leave the place they are self-isolating for the purpose of work - but they can work from home.
If you break self-isolation police can use reasonable force to return you to your home,
