Dr. Declan Bedford:

I presume it comes down to the practicalities. As I mentioned before, highly visible enforcement is the key. We do not get stopped very often on our roads. I first started driving and got my car in 1979, which was an interesting year in the sense that 650 people were killed on the road. That was the environment I was entering. Highly visible enforcement is key. Despite the amount of driving we do, we are very rarely stopped. The more times people are stopped, the safer our roads will become whether they are stopped for speeding, drinking or seat belts. Some 25% of those who die on the roads are not wearing seat belts. That is extraordinary.
