Previous speakers referred to speeding trucks. This is a problem and anyone who says otherwise is wrong. As I drove from Enfield to Dublin this week, trucks were travelling at 70 mph rather than 50 mph. One can only drive at 70 mph on the motorway but trucks were travelling at that speed on ordinary roads. Senator Ryan commented on the varying damage that can be done by vehicles travelling at different speeds and also referred to the length of time it takes to bring a vehicle to a halt. Given the speed at which some of the trucks to which I refer were travelling, they would have almost reached Lucan before they could have stopped.
