I thought the police only used cameras these days?

If your senses are not impaired and your ability to drive is not impaired whats the issue? Are we assuming that someone who has taken drugs is unfit to drive and why should we make that assumption? What about all the people who take prescription drugs? Are we only talking about recreational drugs here? Theres plenty of people out there who dont take drugs but manage to drive badly and from the article above Im getting the impression that theres another bunch out there who do take drugs, who drive badly and yet who appear to have all of their motor and reaction functions working well. Im willing to bet that these people drive like prats with or without drugs.
"drugs can affect your driving" Yes so what, lots of things can affect your driving, the weather, your emotional state, the kids yelling in the back

What happened to the sweat test kits that were announced to great fanfare a few years back?

Alex, Youre telling us that drug abusers spend pounds & pounds on a fix and it doesn't affect them in any way??????
Maybe your dealer is selling you smarties.
I'd ask for my money back.

Grow up...cars kill innocent people at the best of times never mind when drink or drugs are involved.

Why do people drive when intoxicated? Come to that, why do they abuse drugs and alcohol when they know this will do them harm? Why do they drive too close to the car in front while clamping a phone to their ear with one hand?

Surely the answer to all such questions is they think 'It won't happen to me'. Most of us believe this to some extent. It can be useful - to soldiers going into battle, for instance - but on the roads it's a killer.

Because of it, most drivers remain unaware of the hazards about them. Hazard perception is now part of the driving test, but this is not enough. It's taught in advanced driving courses, but the people who sign up for these already have the right attitude, are already safer than most.

The rest think 'hazard' means 'other drivers', so they buy an armoured car, such as a 'Chelsea tractor'. That's a pity. If they thought a bit further, they might find the most dangerous thing near them when they're out and about is themselves.

People who understand the dangers of driving do not drive under the influence. We must give all drivers this perception - but how? By making advanced driving courses compulsory? By pushing crashed cars onto the verge and leaving them there as a reminder? By erecting large posters of the dead and injured?

As to the immediate problem of drug-driving: yes, there should be more patrols; but the police cannot be everywhere, so drivers must mostly police themselves. Yes, we must set legal limits for drugs in the body. If there is a reliable breathalyser, put one in every traffic car. If it's only partly reliable, then take those who fail it for a blood test.

No David Im not saying that at all. What I am saying is that there seems to be enough evidence to indicate that "drugs" dont necessarily affect your ability to drive. So its not just a simple case of saying you took drugs therefore you should not drive. We know for sure and without doubt that alcohol impairs the ability to walk never mind drive, but we cannot be so confident that all drugs do the same. The aim should be to remove motorists who present increased risks to themselves and others from the using the roads, and not just arbitrarily punishing someone because they took a drug of some kind.
For your further information I dont have a dealer. Ive never taken a non prescribed drug in my life and I dont eat chocolate whether its in smartie form or not. Maybe you thought that remark was amusing but it was actually tasteless and rather childish and theres you suggesting that I grow up?

Alex, precisely what illegal drugs don't affect your driving?
I think it would be argued that the majority of the most popular illegal drugs would have an effect.
Cannabis - slows reaction time (much like alcohol)
Amphetimines - likely to cause speeding, and also a cause of sleep deprivation which has similar effects to alcohol
Cocaine - similar to amphetimines
MDMA - as Amphetimines and cocaine
LSD/Psybocilin - hallicinogens and driving, really?

Drug breathalysers as drugs impair driving skills? Ok fair cop.

I also want old age breathalysers, mobile phone breathalysers, screaming kids in the back seat breathalysers, poor eyesight breathalysers, being lost breathalysers, changing the sounds on the radio breathalysers..............ach what p*sh eh?

Total nonsense Dave.
Apart from the being lost one, there is already evidence in the car should the police stop a driver for your other reasons. Not so with being under the influence of drugs.

Nobody questions the legitimacy of using alcohol breathalysers, it's only common sense to have some form of roadside test for being under the influence of drugs.

However, I'm sure you know far more than the police on the subject as you too probably attend accident scenes on a daily basis.
Thought not.

Anon

I suppose you are an expert too? Thought not.

Anon for good reason too probably

Funny how you fail to refute any of the points I made and had to resort to insults.

ANON ....WOULD THAT BE THE SAME ANON FROM THE ..ERI.....THAT DUDE IS AS THICK AS MINCE....WITH A PASTRY ON TOP....HI THICKO..
