The people who wont be breaking the law already abide by this law already.. dont drink and drive.. This law just controls the controlled. Drunk drivers will drive drunk no matter what.

I know LOTS of people who drink just a few drinks and then drive home, which is ok so long as they aren't buzzing much. But I think the idea here is to make people think twice before having the 3 beers and jumping behind the wheel. Not fall on your face drunk but buzzed enough to impair driving somewhat.

Control the controlled... lol. Do you own a tinfoil hat?

I dont know about that,

most people will drive because they think they only had a beer or 2 and they are ok to drive not knowing if they are over the limit or not, but they will assume it's ok and they can stand on 1 foot if the opp asks them to.

if everyone knows that the limit is 0 then they will think twice before driving even after having 1 beer..

people use their own judgement in their own favour

oh yeah just wanted to add my own opinion to my own thread:

while its a step in the right direction what does this realisticaly still say?

-drive in a state of stupification: licene 3days
-drive crisp sober & alert at 50 over, chirp tires, etc: licence 7days.

conclusion ontario prefers u driving buzzed & stupid at teh speed limit, peasant

Trucks are supposed to be limited to 110km now... hmmm ya right trucks are still doing 120km +

no smoking with someone under the age of 16 in the car.. I still see people doing while driving down the highway.

speed limit is 100km... gee who goes that speed.

New cell phone law coming in place soon.. who is really going to stop using it???


these laws only deter people who already abide by the law. Doers will contiune doing.

Control over the controlled.

soooo true. 150 kmh cop will sieze your car? ahahahah I still have people flying by me faster than that on the 401. Now that the summer is in full swing these laws aren't stopping anyone.

Software Problems with a Breath Alcohol Detector

Quote:
Software Problems with a Breath Alcohol Detector
This is an excellent lesson in the security problems inherent in trusting proprietary software:

After two years of attempting to get the computer based source code for the Alcotest 7110 MKIII-C, defense counsel in State v. Chun were successful in obtaining the code, and had it analyzed by Base One Technologies, Inc.
Draeger, the manufacturer maintained that the system was perfect, and that revealing the source code would be damaging to its business. They were right about the second part, of course, because it turned out that the code was terrible.

2. Readings are Not Averaged Correctly: When the software takes a series of readings, it first averages the first two readings. Then, it averages the third reading with the average just computed. Then the fourth reading is averaged with the new average, and so on. There is no comment or note detailing a reason for this calculation, which would cause the first reading to have more weight than successive readings. Nonetheless, the comments say that the values should be averaged, and they are not.
3. Results Limited to Small, Discrete Values: The A/D converters measuring the IR readings and the fuel cell readings can produce values between 0 and 4095. However, the software divides the final average(s) by 256, meaning the final result can only have 16 values to represent the five-volt range (or less), or, represent the range of alcohol readings possible. This is a loss of precision in the data; of a possible twelve bits of information, only four bits are used. Further, because of an attribute in the IR calculations, the result value is further divided in half. This means that only 8 values are possible for the IR detection, and this is compared against the 16 values of the fuel cell.

4. Catastrophic Error Detection Is Disabled: An interrupt that detects that the microprocessor is trying to execute an illegal instruction is disabled, meaning that the Alcotest software could appear to run correctly while executing wild branches or invalid code for a period of time. Other interrupts ignored are the Computer Operating Property (a watchdog timer), and the Software Interrupt.


Basically, the system was designed to return some sort of result regardless.

This is important
. As we become more and more dependent on software for evidentiary and other legal applications, we need to be able to carefully examine that software for accuracy, reliability, etc. Every government contract for breath alcohol detectors needs to include the requirement for public source code. "You can't look at our code because we don't want you to" simply isn't good enough.

I hope the departments that bought these things sue the pants off the manufacturer. I'm not the type to encourage lawsuits but these idiots are obviously negligent.

wonder how many convictions & plea's this system was responsible for?

wonder how many didn't even know of the new rules?

New driving law sees at least 600 people given three-day suspensions since May 1

TORONTO - Police are reporting fewer crashes related to alcohol on provincial roads this holiday long weekend.

But they say it's too early to determine whether Ontario's new drinking and driving penalties are playing a role in the downturn.

Const. Dave Woodford says fatalities involving liquor are down overall.

While he won't have a weekend tally until Tuesday, he said since May 1 there's been at least 600 people given three-day suspensions for driving while in the warn range.

Previously, motorists only received a 12-hour licence suspension for blowing in the warn range, which means driving with a blood alcohol level between 0.05 and 0.08.

Woodford says two people have also been caught a second time, receiving seven-day suspensions of their licences.

As of May 1, drivers caught with a blood alcohol level between 0.05 to 0.08 will have their licence suspended for three days for their first offence, with penalties that increase for every offence.

The third time a driver is caught, their licence is suspended for 30 days, and the motorist will have to complete a remedial alcohol treatment program.

Under the old rules, drivers' licences were only suspended for 12 hours for driving in the warn range, no matter how many times they were caught
