Nope, i saw a mythbusters episode on it. the penny in the mouth doesn't even work. However, those machines can be faulty, so it is always recommended to refuse the test because if you take it and fail, you are guilty no matter what

There are a lot of things that impact the accuracy of a testing device like that, especially when it is in an uncontrolled environment. Start with the test subject:
1. What kind of beer?
2. How much did the subject eat while drinking?
3. What medical conditions does the subject have?

The testing machine"
1. How is it stored?
2. How old is it?
3. Exposed to anything harsh like high humidity? Temp?
4. What environment was it used in? Cold Hot?
The only real way to know is to test it against another testing instrument or use a known solution of alcohol and water

What is a breathalyzer?

A breathalyzer "is a device for estimating blood alcohol content (BAC) from a breath sample" (Wikipedia)
It is sometimes carried around by officers for law enforcement purposes.

The Breathalyzer was wrong and i was kept an hour waiting

Did you use any alcoholic mouthwash? Sometimes the breathalyzer detects alcohol in the breath that has nothing to do with alveolar air. Instead of detecting the alcohol that comes up with air from the lungs, after having been absorbed through stomac and intestines and carried around through blood, the breathalyzer detects the alcohol that sits in the aesofagus or in the throat and mouth, either brought up with a burp or deposited from a mouthwash. Therefore the level of alcohol in these two instances is much higher than if an alcoholic drink were ingested, and therefore the officers have to make sure to keep an eye on the suspect to understand if there is in fact too much alcohol in his or her system or if it's a mistake made by their tool.

Can i buy a breathalyzer to keep track of my drinking when i have to drive?

Yes and No. You can buy your own breathalyzer but it's not a good idea to rely on it.
Breathalyzers can be bought for personal use but these and the ones used for law enforcement do not provide the same accuracy. While the ones that the officers use are approved by the National Highway Traffic Safety Administration and can be faulty sometimes, but provide a more accurate result to BAC (blood alcohol content), the ones that are sold to the public are approved by the FDA and are much less accurate. It is not a good idea to rely on their results as they might lead you to thinking you can drive while instead you drank too much.

What is the legal tolerance on the breathalyzer for someone under 21?

in most states now it is zero tolerance, which means less than .01. one beer in one hour is too much, no matter how much you weigh

What is an interlock button on a 1956 nissian pickup located on right side in dash

It is like a breathalyzer. a safety mechanism design to anayze the alcohol concentration of the driver's breath before he/she can start the car. If the Blood Alcohol Concentration is higher tha 0.4 the engine will be prevented from running and the the driver under the influenced of an alcohol will be prevented from driving. This will save lives.

Most of the mechanism can be re-set so the anyone not undr the alcohol could drive your car.
