Ban for lorry drivers on motorways and A roads? Oh, we wouldn't be able to do that would we.
Why not just give people a minimum 5 year sentence for death by dangerous driving?
5 years would not be far from the average sentence for death by dangerous. You have to give the courts a bit of discretion - some death by dangerous cases are examples of people making gross errors of judgement rather than choosing to drive badly and endanger others.
