If the police get a tip that I was drinking and driving and they show up at my door, I answer, and I'm clearly intoxicated, can the police administer a breathalyzer then? What if I say I haven't left my house all day?
I’ll preface by saying that this answer is not affected by the new laws- it applies equally before and after. So:
Sort of / yes / but...
If you’re clearly intoxicated, an on scene Approved Screening Device shouldn’t be the way to go; someone clearly drunk is already past that and you generally go right to arrest if you have the rest of the pieces of the puzzle. But that aside, I infer that the bigger ‘so what?’ is more whether police can detain or arrest you. Police can do that without a breath sample on scene; the intent of a drunk driving arrest is generally to get a breath sample from a better instrument at the station.
Whether an ASD sample on scene, or going right to arrest, police have to be convinced that the person was in fact operating a motor vehicle. A credible enough witness can give them that even in the face of denials or claims to the contrary. Startlingly, some drunk drivers actually lie to police. A positive ID from a witness versus a denial by a suspect becomes a judgement call by the investigating officer.
But, without continuity of the driver, police will struggle to be able to articulate reasonable grounds to say that they have evidence showing conclusively that the driver was intoxicated while behind the wheel. Recency comes into this too. Is there a lengthy delay? Or do you arrive to find the tail pipe still warm?
Some people absolutely come to the door just after drunk driving. Usually in this case police are investigating a hit and run or some egregiously dangerous driving, or they generally wouldn’t bother once they see the car made it home.
The one difference the new law makes is that if a person should be reasonably expecting to be investigated - hit and run is the best example by far - then the ‘within two hours’ provision can apply for charges. But that has zero impact on the ability of police to get samples, and gives no powers to go into a house that didn’t otherwise exist.
