Police have issued a stark warning telling people not to travel by car to walk their dog or to exercise outdoors.
Officers have been stopping people to issue strong advice and hand out information in a bid to enforce the lockdown rules.
The rules, which came into force on Monday, state that you may only leave your home for four reasons.
As well as medical errands, essential shopping and absolutely essential work you can leave your home once a day to exercise.
Your one trip outside includes walking your dog, the government has said.
Now police are making it clear that exercise has to be done close to your home – you are not allowed to drive to another location to either exercise or walk your dog.
Avon and Somerset Police have been handing out information after stopping drivers at popular dog-walking spots.
It reads: “The government restrictions currently in place do not permit you to use your vehicle to travel to this location to exercise.
“Each and every one of us has been instructed to avoid all unnecessary travel.
You are entitled to exercise once daily. This should be by walking, running or cycling from your home address.
“You should not be driving to a location away from home to carry this out.”
It is unclear whether local authority rules across coastal parts of the country which ban dog walking on beaches from May will be changed to facilitate the new regulations.
Avon and Somerset Police have been approached for comment.
Meanwhile, North Yorkshire Police said it will use checkpoints to stop vehicles and ask drivers if their journey is essential.
Officers will ask motorists where they are going, why they are going there, and reminding them of the message to stay at home, protect the NHS and save lives.
Assistant chief constable Mike Walker said: “The new and significant restrictions announced by the Prime Minister on Monday evening spell out very clearly what each and every one of us must do to save lives. The message is clear and the warning stark. Stay at home, save lives.
“These are the lives of the people we know and love. Our partners, mothers, fathers, sisters, brothers, children, grandparents.
You may never be in such a position again where your simple actions will lead directly to saving lives.”
The force said the checkpoints will be unannounced and could appear anywhere any time.
Devon and Cornwall Police have been manning checkpoints on the main route to Dartmoor.
