In the event of a car accident should police be able to check your cellphone for activity (but not the content) leading up to the incident?

Consider we can't even get these fools to wear a body cam when they are shooting people I don't see any sign whatsoever that they should be trusted with people's data. They can already find out if a phone was used during that time by contacting the provider and asking a simple yes or no question. If anything police consistently prove they cannot be trusted with anything more then that.

Maybe with a search warrant depending on severity of accident/potential criminal accountability.
In most cases for basic traffic accidents checking the phone isn't needed.
It is often clear who is at fault and it dosent matter if they were picking their nose or texting. They are in the wrong.
So my basic response is No

Yes, but only if it's not on a discretionary basis.

I hate the thought of my rights being violated yet, I don't text and drive. And, if I was in an accident with someone who did text and drive, I'd want the police to be able to put it on the incident report. A person should be held accountable with cell phone misuse as they are with DUIs. I suspect the laws will eventually be changed to cover cellphones the way alcohol is covered. People can say no to a check but, then, their conduct comes into question.

Cell phone records can be pulled later, it is not the pigs job to rummage through somebody cell phone.

IMO

That would require a search warrant.

No different than a LEO asking to "Search your car" during a routine traffic stop.

As I have explained... "I have nothing to hide but my civil rights and nothing to do today so I don't mind waiting on your dog."

No. Leave that up to the Courts.

If there's a lawsuit, records can always be subpoenaed from the cell phone company to see if the person was on a phone call at the time of the accident.

They will anyway.

Have done in the UK for a long time.

That's a small price to pay if a person's life is in danger.

I think yes but tbh I am not really sure

No. I don't consent to any police activity involving my property.
