Sounds a bit draconian, Gareth! Dont drive if you are...

Ill?
Tired?
Hungry?
Pregnant?
Wearing new shoes?

Just where do you draw the line?

I will try to explain again. Perhaps it is me not putting my point across very well...

I support any legislation that makes our roads a safer place. What I am getting is, after all these years, there must be a better way of determining if you are fit to drive or not. Testing the blood for alcohol will NOT show up any of the above. More importantly It will not show if you have recently taken drugs either and, apparantly, by the time they get round to a drugs test some drugs (cocaine for instance) could have left your system!

I am left feeling that alcohol testing is being used simply because it is easy and it is what the authorities are used to.

From what I am reading about testing of pupil reaction time this seems like a possibility. Your eyes react to light far more slowly if you are under the influence of drink, drugs or simply under the weather! Surely this would address at least some of the points we have been discussing.

Anyone out there from the medical or law enforcement field care to comment? Could it work? Could it be automated so, for instance, your car would not start unless you pass the test?

Worth investigation surely.
